Pick what suits your setup: electric locks that secure the handle or manual locks that secure the tailgate to the truck. Some let you set the cylinder to your ignition key for one-key convenience. Installation is straightforward with video guidance; plan extra time if a power kit requires routing wiring up to the firewall.
Some locks allow setting the cylinder to match your ignition key. Follow the key setting steps in the kit to pair it. For lost keys, use the number stamped on the face of the lock cylinder to request a replacement key from the lock's manufacturer. If that's not possible, a locksmith can open it so you can swap in a replacement cylinder.
Installation is typically straightforward and can be done in under an hour. Video guides make it easier when printed instructions are minimal or use small font. Be ready for tight electrical connectors; carefully release latches with a small screwdriver. Routing wiring to the firewall takes the most time on power kits. If a bracket hole is slightly off, a light ream can help with fitment.
Pick a power lock if you want the tailgate to lock with your vehicle's power locks or remote. Manual options include a keyed handle or a device that locks the tailgate to the truck. Decide whether you want the handle itself secured or just the gate secured shut. Check your vehicle's access to wiring if you're considering power; some applications use power for the handle lock.
Start by checking the linkage and lock tab move freely. If a screw on the locking tab loosens, apply blue thread locker during reassembly to help prevent it backing out. Inspect riveted joints in the linkage; they should pivot smoothly without binding. If a power lock buzzes but won't throw, check the spring on the lock bolt assembly before assuming the actuator failed.
Power tailgate locks can tie into your vehicle's lock circuit so the tailgate locks with your remote. Plan time to locate the correct wires; instructions for older models may not match newer wire colors. Verify wire location and color with the latest guide before splicing. If vehicle power is lost, applying an external 12V source at the harness can operate the lock to open the gate.
