Why Volkswagen Golf Key Not Working

Dead Battery

The most common reason for a Volkswagen Golf key not working is a dead battery. If the battery in your key fob is low, it may not be able to send a signal to the car’s computer, which will prevent the car from starting. To check the battery in your key fob, look for a small, round, black button on the back of the key. Press this button and the light on the key should come on. If the light does not come on, the battery is dead and needs to be replaced.

Damaged Key Fob

Another common reason for a Volkswagen Golf key not working is a damaged key fob. If the key fob is dropped, it may become damaged and the internal components may be damaged. This can prevent the key fob from sending a signal to the car’s computer. To check if your key fob is damaged, look for any cracks or damage to the case. If you see any damage, the key fob may need to be replaced.

Improper Programming

If your Volkswagen Golf key fob was not properly programmed, it may not be able to communicate with the car’s computer. This can happen if the key fob was not programmed by a qualified technician or if the key fob was damaged during programming. To check if your key fob is properly programmed, you can take it to a Volkswagen dealership or a qualified auto locksmith.

Interference

In some cases, a Volkswagen Golf key fob may not work due to interference from other electronic devices. This can happen if the key fob is near a strong magnetic field or if it is near a device that emits radio waves. To check if interference is causing your key fob to not work, try moving it away from other electronic devices and see if the problem resolves.
