Change the battery

The most common reason why your VW key fob is not functioning is its dead battery. You simply need to change the battery. Replacing the battery is very easy; but first, make sure you are getting the compatible one – the same size, voltage, and specification as the old one.

First, remove the cover of the key fob where its battery is located. Once open, you may use a thin object to pull out the battery. Next is to put in the new battery; make sure it is positioned properly. Once done, put the back cover of the key fob again and press it down until you hear a click sound which means it is locked already.

Reprogram your VW key fob

After changing the battery, you may need to reprogram your VW key fob to work again. The steps for reprogramming vary depending on the model of your Volkswagen.

For the 1997 and older models, you may follow the following steps.

  • Insert your VW key fob in the ignition and turn it on without starting the engine.
  • With the use of your spare key fob, lock the driver’s door. Close all the other doors too.
  • Press the unlock button on your spare key fob until you hear your car’s horn honks.
  • After 6 seconds, press the unlock button again to start the programming process.
  • Turn the ignition off and remove your key fob. Check if your fob will now work.

For the 1997 and newer models, you may follow the following steps.

  1. Insert your VW key fob in the ignition and turn it on without starting the engine.
  2. Close all the doors and lock the doors manually by pressing the lock button on the driver’s door.
  3. Using your spare key fob, press the unlock button 5 times with a second interval. This will make your car’s horn beep.
  4. After 6 seconds, press the unlock button again to delete the memory.
  5. Turn the ignition off and remove your key fob. Check if your fob will now work.

Reset your key fob

If the light in your key fob is flashing, it should be reset. You can only do this using the master key.

First, press and hold the lock or unlock button on your key fob for a second. Make sure your Volkswagen is locked. With the help of the master key, unlock and relock your car. This should reset the key fob by itself.

Check the battery contacts

You already changed the battery of your key fob, but it is still not working? Perhaps, the problem is the battery contacts which will complete the circuit of energy from your new battery.

If these contacts have issues, your key fob will not be powered up. Make sure your battery is firmly placed on it. Check if there is dust and damage in the contacts also which prevents it from functioning.

Check for water damage

Your VW key fob can tolerate some small splatters of water as it is water-resistant. However, it is not waterproof so if it gets soaked underwater, it is most likely to get damaged.

The first thing that you need to do is to remove the battery and dry your key fob immediately once it got submerged. You may use a clean towel to dry the battery and your key fob.

Avoid places where signals can interfere

Your key fob may not connect with your Volkswagen car if there are signal obstructions. If you are near radio towers or satellite systems, the signal can be obstructed.

Avoid going to places like these to prevent problems with your VW key fob.

Check the immobilizer system of your car

Some systems can prevent the connection between your key fob and your car. One is the anti-theft security system which prevents the use of an unknown key to start the car.

If your Volkswagen’s immobilizer system is at fault, it will not detect your key fob as the registered key for your car. You may confirm this when you see a key symbol on your car’s system which is a warning light.

Replace your key fob

If you think you have tried all possible solutions and even asked for the help of a professional but still nothing works, your key fob may be defective.

The simple solution to this is to get a new one. You can purchase a new key fob from your authorized dealer.
