5 Main Reasons Why Your Keyless Remote Car Key Isn't Working

If your keyless remote car key isn't working, you might experience mixed feelings—from frustration to downright worry and disappointment.

Here are two reasons why your keyless remote might not be functioning properly, with tips on how to troubleshoot and fix the problem. So, if you constantly have trouble with your keyless entry remote system, read on for some helpful advice.

A Dead Key Fob Battery

A dead battery is one of the most common reasons why a key fob stops working. Over time, the battery will lose its charge and will eventually die. If you find that your key fob isn't working as consistently as it used to, it's probably time to replace the battery.

Key fobs often differ, depending on the car model. But for most types, you can easily replace the battery yourself—just follow these steps.

First, locate the screw that secures the back cover of the key fob. Remove the screw with a small Phillips head screwdriver and then pry open the back cover of the key fob.

Once you've opened the key fob, you should see the battery inside. Gently remove the old battery and replace it with a new coin cell battery. After you've replaced the battery, reassemble the key fob and test it out. If it still doesn't work, you might need to contact a locksmith for professional help.

Troubleshooting Tip: Not sure what kind of battery you need? Check the old battery to see what type it is and then buy a replacement from your local hardware store or online.

A Faulty Key Fob

In some cases, the key fob itself might be damaged or faulty. If you've replaced the battery and the key fob still isn't working, there might be an issue with the key fob itself.

One way to test if the key fob is working properly is to use a spare keyless remote for your car if you have one. If the other remote doesn't work either, then the problem is probably with your car's receiver and not the key fob. The receiver's job is to receive the signal from the key fob and then activate the car's locks.

But if you don't have a spare keyless remote, you can try to reset the key fob. Resetting the key fob will usually solve any minor issues and is a pretty simple process. To do this, remove the key fob's battery and then press and hold the unlock button for about a few seconds. After that, reassemble the key fob and test it out.

If you still have no luck, you can try to reprogram the key fob. But reprogramming a keyless remote system is a bit more complex and requires professional help from a qualified locksmith.
