This guide will walk you through the steps to troubleshoot a keyless entry system that isn’t working, including checking the battery in your key fob, programming your key fob to your car, and replacing the keyless entry module.

Why Volkswagen Keyless Entry Not Working

Dead or Weak Battery

The most common reason for a keyless entry system not working is a dead or weak battery in the key fob. If the battery is too low, the key fob will not be able to send a signal to the car, and the keyless entry system will not work. To check the battery, remove the key fob from the key ring and look for a small, round battery in the back. If the battery is bulging, leaking, or corroded, it needs to be replaced. You can usually find replacement batteries at most stores that sell batteries.

Incorrect Programming

If the key fob is not programmed correctly to the car, it will not be able to communicate with the car’s computer and the keyless entry system will not work. To program the key fob, you will need a Volkswagen dealer or a qualified automotive technician.

Damaged Key Fob

If the key fob is damaged, it may not be able to send a signal to the car, and the keyless entry system will not work. Common causes of damage to key fobs include dropping them, getting them wet, or exposing them to extreme heat or cold. If you think your key fob may be damaged, you can try replacing the battery or taking it to a Volkswagen dealer or a qualified automotive technician to have it checked.

Interference

Certain electronic devices, such as cell phones, can interfere with the keyless entry system. If you are having trouble with your keyless entry system, try turning off your cell phone and see if that fixes the problem.

Software Problems

In rare cases, a software problem in the car’s computer can cause the keyless entry system to not work. If you have tried all of the other solutions and your keyless entry system is still not working, you may need to have the car’s computer reprogrammed.
