It’s common for power locks on cars to act finicky from time to time. However, if you have an ongoing issue with getting your locks to function, you might need to troubleshoot the problem and head to an auto parts store for replacement parts. Here’s what you should know about solving this issue. 

What Causes Car Door Locks to Stop Working? 

Isolating the problem with malfunctioning locks can be tricky since there are many potential causes. Fortunately, almost any part that could be causing the issue is replaceable at an auto parts store.

Start by checking the battery in your remote key fob. If it’s dead, you won’t be able to use the fob. If a fresh battery doesn’t solve the problem, the key fob itself may be broken, and you’ll need to replace it.

If your key fob has power, but the locks don’t engage, it could be an electrical issue. Power locks require electricity to function. A blown fuse, faulty wiring, or a broken solenoid could prevent electricity from flowing to the locking mechanism. 

Lastly, there may be an issue with the locks themselves. If they aren’t seeding into place when you close the doors, there may be a missing or damaged component that’s preventing them from engaging. 

How Can You Fix Common Lock Problems? 

Most of the time, you can fix lock issues on your own with items from the auto parts store. 

If you suspect an electrical issue, start by getting new fuses or a replacement solenoid for the door. Swap these parts out individually so that you can keep track of what item may be causing the problem. If the issue is related to wiring, you may want professional help since electricity can be dangerous to work with.

You can also find kits for replacing the locks at the auto parts store. Replacing your own locks is more complex than swapping out fuses or a battery, but it’s still possible to do on your own.

The process involves removing the door cover and liner, pulling the lock tumbler out of its casing, inserting the new lock cylinder in its place, and reassembling the lock and door. It’s helpful to consult instruction manuals or video tutorials for this particular fix.
