Damaged Key Fob

Another common reason for a Volkswagen Tiguan key not working is a damaged key fob. If the key fob is dropped or damaged, it may be broken internally, which will prevent it from sending a signal to the car’s computer.

Improper Programming

If a Volkswagen Tiguan key fob is not properly programmed, it will not be able to start the car. This can happen if the key fob is not programmed by a Volkswagen dealer, or if the key fob is damaged and needs to be reprogrammed.

In some cases, a Volkswagen Tiguan key may not work because of a faulty ignition switch. If the ignition switch is damaged, it may not be able to properly communicate with the key fob, which will prevent the car from starting.
