Cars these days are playing an essential role in our everyday life and modern cars these days are faster, safer, and have a much better security systems. Car key technology has also developed a lot since it first came out, far beyond the simple metal key we used to rely on. In this blog we’ll cover the most common reasons why your car key might stop working.
Power Issues
If your car key isn’t working right, then the first thing you should check is the car’s battery. This problem often appears when there are too many electronic accessories plugged into your car power system and draining the battery, or if the car’s battery has drained because it’s reached the end of its lifespan. First unplug any electronic device that’s connected to the car power system and see what happens. If it is still not working, then you need to replace the car’s battery.
Key Fob Dead Battery
Since car key fobs run on small batteries that can die over time, they require a replacement. It is a simple task, and you can absolutely do it yourself. But if changing the battery doesn’t solve the problem, then the issue might be with its programming or internal chip malfunction. In both cases, this is better handled by a professional automotive locksmith.
Damaged Car Keyless Remote
The most common reason is probably a dead battery and we’ve already discussed it. Other issues may include signal interference, damaged buttons or a problem with the car’s receiver. The most common solution is to reprogram the remote, and if that is not working then it needs to be replaced.
Car’s Computer Key Reading Errors
Sometimes the car’s computer may fail to read the transponder chip in your key correctly. It is a well-known issue, more common in older vehicles that use analog systems, while newer models rely on digital key readers. So if you’re driving an older car and the key isn’t being recognized, then you can lightly sand the metal part of the key to help the ignition’s electromagnet make better contact with the chip inside.
