Why Volkswagen Jetta Keyless Entry Not Working

Dead Key Fob Battery

The most common reason for a Volkswagen Jetta keyless entry not working is a dead key fob battery. The key fob battery is a small, round, button cell battery that powers the key fob’s transmitter. When the battery dies, the key fob will no longer be able to send a signal to the car, and the keyless entry system will not work.

Faulty Key Fob Transmitter

In some cases, the key fob transmitter itself may be faulty. This can happen if the key fob is dropped or damaged, or if there is a problem with the internal circuitry. If the key fob transmitter is faulty, it will not be able to send a signal to the car, and the keyless entry system will not work.

Faulty Keyless Entry Receiver

The keyless entry receiver is a small, electronic module that is located in the car. The receiver receives the signal from the key fob transmitter and unlocks the doors. If the keyless entry receiver is faulty, it will not be able to receive the signal from the key fob, and the keyless entry system will not work.

Interference from Other Electronic Devices

In some cases, keyless entry systems can be affected by interference from other electronic devices. This can include devices such as cell phones, radios, and microwaves. If there is a lot of interference in the area, it can prevent the key fob from sending a signal to the car, and the keyless entry system will not work.

Software Problems

In some cases, keyless entry problems can be caused by software problems in the car’s computer. These problems can be caused by a corrupt software file, a software update that was not installed correctly, or a problem with the car’s computer itself. If there is a software problem, it can prevent the car from receiving the signal from the key fob, and the keyless entry system will not work.
