RERPRO Locking Fuel Cap for Ford Bronco & F150 (2021–2025) Matte Black — Keyed Alloy Cylinder, 2 Keys

RERPRO locking gas cap replaces the factory filler plug on 2021–2025 Ford Bronco (2- and 4-door) and compatible F150 models, securing your fuel with a keyed alloy cylinder and two keys.

This locking fuel cap is designed as a direct-fit replacement to help prevent unauthorized access to the tank on select Ford Bronco and F150 trucks. Constructed with a metal lock cylinder, ABS housing, and copper keys, the unit installs without tools and operates as a simple plug-and-lock system. It’s sold as a single set with two identical keys and comes in a matte black finish to blend with factory trim.

Will this locking cap fit my Bronco or F150?

The RERPRO cap is made for 2021, 2022, 2023, 2024 and 2025 New Ford Bronco two-door and four-door models, and fits many F150 trims including Tremor and Limited variants. It is not compatible with Bronco Sport or Raptor models—check your OEM filler dimensions before ordering.

• Compatible: 2021–2025 Ford Bronco (2/4 door)
• Compatible: F150 series including Tremor/Limited where OEM filler matches
• Not compatible: Bronco Sport and Raptor
• Sold as: 1 locking cap + 2 keys

How secure is the RERPRO locking gas cap?

The lock uses a metal alloy cylinder and keys to reduce casual tampering and deter fuel theft. The ABS outer housing resists weather and road debris, while the copper key provides smooth operation. Keep in mind the product is a mechanical deterrent—not a guarantee against determined theft.

• Alloy lock cylinder for durability
• ABS housing resists impact and elements
• Copper key for reliable turning and wear resistance
• Requires key to open and locks into the filler opening

How easy is installation and removal?

Installation is plug-and-play: insert the cap into the fuel filler and turn the key to lock. No drilling, wiring or special tools are required, and the locking mechanism engages with the vehicle’s filler retention. Removing the cap without the key would damage the internal retention, so treat keys carefully.

• Tool-free installation—just plug and lock
• Quick access using the provided keys
• Removal without the key may permanently damage the cap
• Ideal for drivers who want a simple retrofit solution

What materials and components are included?

The set includes one locking fuel cap and two identical keys. Internal components blend a top-grade alloy lock cylinder with a reinforced ABS exterior shell for longevity. The cap is engineered to replace worn or non-locking OEM filler plugs while maintaining a low-profile appearance.

• Included: 1 locking gas cap, 2 keys
• Internal: alloy lock cylinder for strength
• Exterior: quality ABS housing for impact resistance
• Keys: copper construction for smooth operation

Who is this for? The RERPRO locking gas cap is aimed at Bronco and F150 owners who want a straightforward, mechanical way to secure their fuel filler. It’s a practical upgrade for parked vehicles in public or high-traffic areas, off-road rigs, and anyone replacing a loose or missing OEM cap. If you drive a Bronco Sport or Raptor, or require a vehicle-specific factory-coded cap, confirm compatibility before purchasing.
