Any type of automotive repair can be costly. If your automatic car door lock isn’t working, here are four easy steps to repair it.
Step 1 – Check the Least Obvious First
It should be the most obvious, but most of the time we simply don’t think of the auto key lock on our keychains. Called a key fob, it’s operated by a battery that does wear out after several years of use. Replace the battery, then check it to see if it is in working order again.
Step 2 – Check Other Door Locks
Before rushing to rip off the door panel, and replacing wires and parts, check the other locks. Do they work? If not, then you may have a blown fuse. If they do work, the problem is most likely in the door lock solenoid.
Step 3 – Work the Lock Manually
While the key is in, work the door lock manually up and down while using the auto lock at the same time. If the lock tries to move, then it is a frozen lock mechanism.
Step 4 – Move Door Back and Forth
Hold the lock button down while you slowly open and close the door. If the lock works, then you have a broken or frayed wire that needs to be changed or repaired.
Try these tips for a quick way to repair car door lock. If these tips do not work and you can’t find the problem, you’ll need to see a mechanic.
