How to Repair Car Door Locks

If you hear a buzzing or an unexpected 'rat-atat-a -tat' locking or unlocking your car door, it might be time to replace the actuator. It may require some disassembly based on the model and make of your car.

Before attempting to fix it yourself, have an auto locksmith present a diagnosis so they can perform the repair quickly and without causing any further damage. Most of the time, the solution will be straightforward:





Locks that are not secure or damaged

If your door lock won't turn it could be caused by loose or disconnected rods in the latch mechanism. These rods can bind or rust and prevent the door handle from connecting to the latch, allowing the door to be opened by hand. Before replacing the rods it is important to thoroughly examine the connections and rods. You'll need access to one of your other car doors to check the linkage that connects the handle to the latch.

A jammed lock might just need to be lubricated. If the key won't turn or the handle is stiff to be touched, apply lubricant to the handle and then move it back and forward until it feels smooth. If this doesn't work try lubricating the key and sliding it into and out of the lock. This will loosen the tumblers.

Rust or debris may also prevent the key from turning inside the lock mechanism. Cleaning the lock mechanism and keyhole thoroughly can eliminate these obstructions which will allow your lock to function correctly again.

Another common hurdle in locking and unlocking cars is an overblown fuse that connects to the power lock system. Over time, high voltage can cause damage to these fuses and cause them to cease working. If you know what to do, it is easy to identify this problem and fix it.

Broken or missing parts are more serious issues that require a professional fix. If the latch or lock cylinder are damaged, they will require replacement. This requires removal of the door's panel and disconnecting the cables and rods. The lock actuator should be removed as well. This is a more difficult repair, but is still achievable by a novice mechanic.

Install the new lock cylinder once the replacement is complete. Test it to ensure that it works correctly. Follow the instructions given by the manufacturer to disconnect the deadlock before you use the door. If you're not sure about completing these steps, call your local Nissan service centre for assistance.
