Finding the right 2017 silverado locking fuel door solution can be harder than it sounds because listings often mix locking fuel caps, decorative filler-door covers, gasoline applications, and diesel applications. The safest choice depends on your Silverado’s exact model, engine, fuel type, and the part number printed on the original cap.
My first choice is Koerlam 12495845 Locking Fuel Cap Replacement. It is specifically positioned for the 2012–2017 Silverado 1500, and its installation instructions address common problems such as starting with the key in the wrong position or failing to turn the cap fully to lock.
My second choice is SEEBOO Locking Gas Cap. My alternative is the SEEBOO Locking Gas Cap for Chevy and GMC vehicles. Its broad compatibility list may suit a buyer who wants one replacement for a 2017 Silverado 1500 or several vehicles, while the reinforced ABS construction and sealing rubber are aimed at everyday weather exposure.
This comparison explains where each product fits, why the first two rank above the others, and which limitations deserve attention before ordering. You will also find practical guidance on matching the part, installing it correctly, avoiding common mistakes, and caring for a locking fuel cap.
5 Best 2017 Silverado Locking Fuel Door
I selected these products by weighing direct Silverado relevance, the clarity of the stated fitment information, useful installation or ownership details, and customer-feedback evidence where available. Brand variety was included when an alternative offered a meaningfully different use case, but products with an obvious vehicle or fuel-type mismatch were ranked lower.

Koerlam 12495845 Locking Fuel Cap Replacement
The Koerlam cap earns the top position because its stated application is unusually close to the target vehicle: Chevrolet Silverado 1500 models from 2012 through 2017. That direct fitment focus is more helpful than a huge compatibility list when the buyer owns a 2017 half-ton Silverado and wants a straightforward replacement rather than a universal-looking part.
The installation guidance is another practical strength. Koerlam specifically says to turn the key to “OPEN/UNLOCK” before installing or removing the cap. After tightening, the key should be turned to “LOCK” and removed. Those details matter because a locking cap can appear defective when it was simply installed with the cylinder in the wrong position.
There is also guidance for a cap that will not align with the filler-neck threads: remove it, reseat it flat, and rotate it clockwise until it locks fully. This makes the part friendlier for a first-time installer who may not recognize that cross-threading or uneven seating is the real problem.
The main limitation is that Koerlam clearly identifies this as an aftermarket replacement, not an original-equipment part. Fitment should therefore be confirmed against the old cap, photos, and model information before ordering. It is best suited to a Silverado 1500 owner who values direct year coverage and simple setup instructions.
Pros
- Directly listed for 2012–2017 Chevrolet Silverado 1500 models
- Clear key-position instructions for installation and removal
- Explains how to correct thread alignment and locking problems
- Focused application is easier to evaluate than an extremely broad list
Cons
- Aftermarket rather than an original-equipment part
- Fitment still needs confirmation before purchase
- Not presented as a complete decorative fuel-door assembly
My Opinion
This is the most sensible starting point for a 2017 Silverado 1500 owner who wants a locking replacement cap and does not need a full exterior fuel-door cover. The direct model-year focus and useful setup advice give it the clearest buyer path, provided the original cap and vehicle details match.
SEEBOO Locking Gas Cap
The SEEBOO locking gas cap ranks second because it combines strong Silverado coverage with a much wider vehicle list. Its Chevrolet fitment information includes Silverado 1500 models from 2012–2017, along with various Silverado 2500 and 3500 applications and other Chevy vehicles. That breadth can be useful for households or fleets with more than one compatible vehicle.
Its stated construction also speaks to ordinary ownership concerns. Reinforced ABS plastic and sealing rubber are described as being more resistant to cold and heat, with the goal of maintaining a tight seal in changing weather. A properly sealing fuel cap helps prevent dirt and moisture from reaching the filler system, although buyers should still verify that the cap is intended for their specific fuel system.
SEEBOO lists replacement references including 10504 and 77300-47020, but the wide application range means those numbers should not be treated as automatic proof of compatibility. The listing itself tells buyers to confirm suitability before ordering. That is particularly important because the same product family is shown for vehicles from Chevrolet, GMC, Toyota, Honda, Nissan, and many other brands.
This option may appeal more than the Koerlam to someone who values broad cross-vehicle coverage, a large body of available customer feedback, or the possibility of using the same style of cap on another compatible vehicle. The trade-off is that the buyer must do more careful fitment checking instead of relying on the product’s general Silverado mention.
Pros
- Lists 2012–2017 Silverado 1500 compatibility
- Broad Chevy and GMC coverage for multiple vehicle applications
- Reinforced ABS plastic and sealing rubber are intended for weather exposure
- Replacement reference numbers are provided for comparison
Cons
- Very broad fitment list can make selection confusing
- Compatibility must be confirmed for the exact vehicle
- Not specifically presented as a complete locking fuel-door cover
My Opinion
SEEBOO is a strong alternative when broad compatibility is useful, but it requires more homework than the Koerlam. I would favor it for a buyer who can verify the replacement number or vehicle application and wants a cap described for varied weather conditions.
MotoRad Locking Fuel Cap
MotoRad offers the broadest mainstream truck coverage among the higher-ranked choices. The supplied fitment information includes Chevrolet Silverado 1500 from 2008–2020, Silverado 2500 from 2012–2021, and Silverado 3500 from 2012–2020. It also lists GMC Sierra applications, including Sierra 1500 from 2012–2020, which makes this option relevant to buyers comparing closely related GM trucks.
Several associated part numbers are shown, including 20968135, 7D0201551C, 533201551C, 1H0201551, and 191201551D. These references can make cross-checking easier if one appears on the old cap or in a vehicle-parts catalog. However, the listing explicitly advises using Amazon ConfirmedFit, so the long fitment list should be treated as a starting point rather than a guarantee.
The product also extends beyond Silverado and Sierra to vehicles such as the Equinox, Cruze, Traverse, Terrain, Tahoe, and numerous other makes. That versatility may be valuable for a parts buyer who handles several applications, but it is less helpful for someone who simply wants a no-guesswork 2017 Silverado 1500 replacement.
MotoRad’s position reflects that balance. It has meaningful GM truck coverage and available customer-feedback evidence, but the information does not provide the same Silverado-specific installation tips supplied by Koerlam. Buyers should compare the original cap, confirm the engine and model details, and make sure they need a locking fuel cap rather than a complete fuel-door assembly.
Pros
- Broad Silverado and Sierra year coverage
- Includes several cross-reference part numbers
- Applies to multiple Chevrolet and GMC vehicle lines
- Useful choice for buyers handling several compatible applications
Cons
- Requires careful ConfirmedFit verification
- Large vehicle list may create unnecessary uncertainty
- Supplied data does not include detailed installation instructions
My Opinion
MotoRad is a credible-looking option for a buyer who wants wide GM coverage and can verify the part number. For a single 2017 Silverado 1500, however, I would place its versatility behind the more directly targeted Koerlam and the Silverado-inclusive SEEBOO.
Aunginsy Aluminum Locking Fuel-Tank Cap Cover
The Aunginsy product is not a direct match for a 2017 Chevrolet Silverado. It is listed for Toyota Tacoma models from 2016–2023, specifically trucks with a 5-foot bed. Its inclusion is useful mainly as a warning against confusing a decorative locking fuel-door cover with a replacement cap intended for a Silverado.
This product takes a different approach from the first three. It is described as a CNC aluminum-alloy cover with an anodized coating, a keyhole, and a trim-style design intended to fit the original vehicle design. The stated purpose is both visual protection and a lock-and-key mechanism for the fuel-tank area, rather than simply replacing a threaded cap inside the filler neck.
Installation is described as a direct process using the supplied screws, but the buyer must confirm the Tacoma bed configuration before purchase. Aunginsy also states that the screw size was modified, which makes checking the latest fitment information especially important if comparing this item with older photos or instructions.
The 24-month guarantee service is a positive ownership detail within the supplied information, especially for a product that depends on precise exterior fit. Still, that support does not overcome the vehicle mismatch for a Silverado owner. This belongs near the bottom because it demonstrates the type of locking fuel-door accessory some truck owners want, but it should not be ordered for a Chevrolet Silverado based on the locking function alone.
Pros
- Aluminum-alloy construction with an anodized coating
- Combines a locking mechanism with an exterior trim cover
- Listed as easy to install with supplied screws
- 24-month guarantee service is stated by the brand
Cons
- Designed for 2016–2023 Toyota Tacoma trucks
- Only listed for the 5-foot bed configuration
- Not a suitable direct choice for a 2017 Silverado
My Opinion
Aunginsy is included for category context, not as a Silverado recommendation. It may suit a Tacoma owner seeking a visible anti-theft trim cover, but the vehicle-specific design makes it a poor choice for anyone searching for a Chevrolet replacement cap.
ROVIKE 10591D Locking Diesel Fuel Cap
ROVIKE’s 10591D cap is aimed at diesel applications and heavy-duty trucks, including Chevrolet Silverado 2500 HD models from 2001–2020 and Silverado 3500 HD models from 2007–2020. It also lists a large collection of older Chevy, GMC, Ford, Dodge, Jeep, and other applications. That makes it relevant to certain heavy-duty owners, but not the typical 2017 Silverado 1500 gasoline buyer.
The most important distinction is the word “diesel.” A cap designed for a diesel fuel system should never be selected simply because the truck’s name appears in the compatibility list. Engine type, fuel type, model year, and the original cap’s specifications all need to agree before ordering.
The long compatibility list may help a parts professional or owner of an older work truck who already knows the 10591D reference is correct. It also includes Silverado 2500 HD and 3500 HD applications that overlap the 2017 model year. However, the supplied information does not establish that it fits a 2017 Silverado 1500, and it should not be treated as a universal GM locking cap.
ROVIKE ranks fifth because it fills a specialized need rather than the central 2017 Silverado 1500 search. Its 3.5-star customer-feedback figure and 61 listed ratings provide some buying context, but exact fitment and diesel compatibility matter more than the feedback count here. Heavy-duty owners should verify the truck configuration before installation.
Pros
- Lists Chevrolet Silverado 2500 HD and 3500 HD applications
- Also covers selected GMC, Ford, Dodge, and Jeep vehicles
- Useful reference for certain diesel fuel systems
- Clearly identifies the 10591D product number
Cons
- Diesel-focused rather than a general Silverado 1500 choice
- Not established as compatible with a 2017 Silverado 1500
- Extremely broad fitment list requires careful verification
My Opinion
ROVIKE is only worth considering when the truck is a listed heavy-duty diesel application and the original cap or part reference matches. For a standard 2017 Silverado 1500, it is the wrong direction and should be passed over in favor of a gasoline-cap option with direct 1500 coverage.
How I Selected These 2017 Silverado Locking Fuel Door Options
The central selection issue is separating a true locking fuel cap from a complete fuel-door cover. The products above do not all serve the same purpose: Koerlam, SEEBOO, MotoRad, and ROVIKE are presented primarily as replacement caps, while Aunginsy is an exterior locking cover for a Toyota Tacoma.
I gave the highest priority to direct relevance for the 2017 Silverado 1500, then considered the clarity of the fitment information and the practical details supplied for installation or ownership. A product with a huge application list was not automatically ranked above a product focused on the target truck.
Best match does not always mean the longest compatibility list. It means the vehicle, fuel type, body configuration, and replacement reference all agree.
Customer-feedback evidence was considered when supplied, but it cannot replace fitment confirmation. The available figures vary across the listings, and none of them proves that a part will fit every Silverado configuration. Brand variety was retained to show useful alternatives, including a broad GM option, a specialized diesel cap, and an exterior cover that illustrates a different product category.
What the ranking means
Rank one is the most direct match for the stated search because Koerlam identifies the 2012–2017 Silverado 1500 and provides useful installation corrections. SEEBOO follows because it includes the target Silverado while offering broad Chevy and GMC coverage.
MotoRad is a strong cross-reference candidate but needs ConfirmedFit checking. Aunginsy and ROVIKE are lower because their intended vehicles or fuel systems do not align as closely with a typical 2017 Silverado 1500.
How to Choose a 2017 Silverado Locking Fuel Door
Before ordering, identify whether you need only the threaded fuel cap or a visible locking cover around the filler opening. Most Silverado owners searching for theft deterrence need a locking cap, but the correct answer still depends on the truck’s exact configuration and the shape of the original part.
- Confirm the model and bed configuration: A Silverado 1500 is not interchangeable with every Silverado 2500 or 3500 listing, and a Tacoma-specific cover is not a Silverado part.
- Match the fuel type: Do not use a diesel cap listing for a gasoline truck merely because the model name looks similar.
- Compare the original cap: Check its threads, shape, key position, tether or attachment arrangement, and any printed part number.
- Use fitment tools carefully: Amazon ConfirmedFit and manufacturer application lists are useful, but compare the result with the actual vehicle and original part.
- Decide whether you need a cap or cover: A cap seals the filler neck; a decorative cover changes the exterior appearance and may attach with screws.
Cap versus complete fuel-door cover
A replacement locking cap sits at the filler neck and is removed when refueling. It is usually the simpler solution when the goal is to add a lock or replace a damaged seal. A complete fuel-door cover is an exterior accessory that may require a particular body shape, mounting point, bed length, or screw pattern.
The phrase 2017 silverado locking fuel door can describe either product category in search results, which is why reading the actual application is essential. If a listing names a different truck or mentions a special bed length, treat that as a strong warning rather than a minor detail.
When a cross-reference number helps
Part numbers can narrow the search, especially when a listing provides several references such as MotoRad’s group of associated numbers or SEEBOO’s replacement references. Use them as comparison tools, not as permission to skip vehicle verification.
A matching number is most useful when it appears on the old cap, in a reliable parts catalog, or in a confirmed vehicle record. A number copied from a broad marketplace listing without matching the original component may lead to an incorrect order.
Installation and First Use Tips
Locking caps are simple parts, but the key cylinder and threads need to be handled in the right sequence. Work with the engine off, park on a level surface, and keep dirt away from the filler opening while the old cap is removed.
- Compare the new cap with the old one before removing anything. Check the diameter, thread pattern, sealing area, and key operation.
- Clean loose dirt around the filler neck without pushing debris into the opening.
- Set the new key to the manufacturer’s open or unlock position before installation when the instructions call for it.
- Place the cap flat and turn it clockwise by hand. Do not force it if the threads do not engage smoothly.
- Tighten the cap as instructed, then turn the key to the locked position and remove it.
- Test the cap gently by attempting to loosen it with the key removed. Do not use excessive force.
Koerlam’s instructions are especially clear about the key position and thread alignment. If the cap will not sit flat, remove it and start again rather than tightening against resistance. A crooked cap can damage threads or fail to seal correctly.
Compatibility Checks Before You Order
Fitment is the most important ownership issue with this type of part. Listings often combine several generations, engines, and body styles, so a vehicle name alone is not enough to establish compatibility.
Use this quick verification sequence
- Write down the exact year, make, model, trim, and engine.
- Identify whether the truck uses gasoline or diesel.
- Check whether it is a Silverado 1500, 2500 HD, or 3500 HD.
- Photograph the old cap and its locking cylinder for comparison.
- Look for a molded or printed part number.
- Read the return and support information before installing an uncertain part.
Do not install a product if the listing says it fits a different vehicle but the part merely looks similar. Aunginsy’s Tacoma-specific bed requirement and ROVIKE’s diesel focus show why visual similarity is not a reliable fitment test.
If the replacement does not match the old part before installation, stop and verify it. Do not try to make an uncertain cap fit by force.
How to Keep a Locking Fuel Cap Working
Routine care is mostly about keeping the lock, seal, and threads clean. Fuel filler areas collect dust, road spray, and debris, especially on trucks used on gravel or in winter conditions.
- Wipe dirt from the cap before inserting the key.
- Keep the key dry and free of grit.
- Inspect the rubber sealing area for cuts, flattening, or accumulated debris.
- Check that the cap remains flat and tight after refueling.
- Do not hang a heavy key ring from the lock while the key is inserted.
- Replace a cap that develops cracks, leaks, or a cylinder that will not turn normally.
Do not apply an unknown lubricant near the fuel filler opening. If the lock becomes stiff, follow the product maker’s care guidance and keep any maintenance product away from fuel contamination and the sealing surface.
Common Mistakes to Avoid
Most problems come from buying by appearance or installing without checking the lock position. The following mistakes are easy to avoid with a short pause before ordering or refueling.
- Choosing by truck name alone: Silverado 1500, 2500 HD, and 3500 HD applications can differ.
- Ignoring fuel type: A diesel cap is not a safe default for a gasoline Silverado.
- Confusing a cover with a cap: Exterior trim accessories may require screws and vehicle-specific mounting points.
- Forcing misaligned threads: Remove the cap and reseat it flat if it does not turn smoothly.
- Leaving the key in the wrong position: Follow the open and lock sequence provided for the specific cap.
- Skipping the old-part comparison: A photo and part-number check can reveal a mismatch before installation.
Another common mistake is assuming that a broad fitment list is stronger evidence than a focused one. In practice, the best listing is the one that matches the complete vehicle details, not necessarily the one that names the most makes.
FAQ: 2017 Silverado Locking Fuel Door Questions
Does a 2017 Silverado usually need a locking cap or a full fuel-door cover?
That depends on the goal. A locking cap replaces the cap at the filler neck and is the simpler anti-tampering solution. A full fuel-door cover is an exterior accessory and must match the truck’s body and mounting design.
Is the Koerlam cap intended for a 2017 Silverado 1500?
Yes, the supplied application identifies the Koerlam 12495845 replacement for Chevrolet Silverado 1500 models from 2012 through 2017. Confirm the original cap and vehicle details before ordering because it is an aftermarket part.
Can a SEEBOO cap fit other Chevy and GMC trucks?
The supplied compatibility information lists many Chevy and GMC applications, including Silverado 1500 from 2012–2017 and several Sierra, Savana, and other vehicles. Buyers should confirm the exact vehicle and replacement reference before purchase.
Can the ROVIKE 10591D cap be used on a Silverado 1500?
The supplied information focuses on diesel applications and lists Silverado 2500 HD and 3500 HD vehicles, not a confirmed 2017 Silverado 1500 application. It should not be selected for a 1500 without authoritative fitment confirmation.
Why might a new locking cap fail to lock after installation?
The key may not be in the required open position during installation, or the cap may not be seated flat on the threads. Remove it, reset the key position, align the cap carefully, and follow the product-specific locking sequence.
Final Thoughts
For the target 2017 silverado locking fuel door search, the Koerlam 12495845 Locking Fuel Cap Replacement for Chevrolet Silverado 1500 is the clearest first choice because its stated year range directly covers the truck and its instructions address common installation errors. The SEEBOO Locking Gas Cap for Chevy GMC Silverado is the better alternative for buyers who want broader vehicle coverage and can verify the fitment details carefully.
