Why Volkswagen Keyless Ignition Not Working

Dead or Weak Battery

The most common reason for a keyless ignition not working is a dead or weak 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 LED light on the fob. If the light is not lit, or if it is dim, the battery needs to be replaced.

Faulty Key Fob

Another common cause of a keyless ignition not working is a faulty key fob. If the key fob is damaged, it may not be able to send a signal to the car’s computer, which will prevent the car from starting. To check if your key fob is faulty, try using it to lock and unlock the car doors. If the doors do not lock or unlock, the key fob is likely faulty and needs to be replaced.

Faulty Antenna

The antenna in your car is responsible for receiving the signal from your key fob. If the antenna is damaged, it may not be able to receive the signal from the key fob, which will prevent the car from starting. To check if the antenna is faulty, try moving the key fob closer to the car’s ignition. If the car starts when the key fob is close to the ignition, the antenna is likely faulty and needs to be replaced.

Faulty Ignition Switch

The ignition switch is responsible for sending the signal from the key fob to the car’s computer. If the ignition switch is faulty, it may not be able to send the signal, which will prevent the car from starting. To check if the ignition switch is faulty, try starting the car with a different key. If the car starts with a different key, the ignition switch is likely faulty and needs to be replaced.
