How To Fix Immobiliser Issues In Your Volkswagen

What is an immobiliser?

An immobiliser is an electronic security system that prevents your car from being started without the correct key. It works by sending a unique signal from the key to the car’s engine control unit (ECU). If the ECU does not receive the correct signal, it will not allow the engine to start.

What are the signs of an immobiliser problem?

The most common sign of an immobiliser problem is that your car will not start. Other signs include:

  • The immobiliser warning light on your dashboard is flashing or on constantly.
  • Your car starts but then stalls immediately.
  • Your car starts but runs erratically.
  • You have difficulty unlocking or locking your car doors with your key fob.

How to fix immobiliser issues

There are a few things you can try to fix immobiliser issues yourself:

  • Check your key fob battery. A dead key fob battery is a common cause of immobiliser problems. Replace the battery and see if this fixes the problem.
  • Try your spare key. If your car still won’t start with your spare key, then the problem is likely with the immobiliser system itself.
  • Reset the immobiliser. Some Volkswagen models have a procedure for resetting the immobiliser. Consult your owner’s manual for instructions.

If you have tried all of the above and your car still won’t start, you will need to take it to a Volkswagen specialist for diagnosis and repair.

Common immobiliser problems in Volkswagen

Volkswagen Key Fob

Some of the most common immobiliser problems in Volkswagen cars include:

  • Faulty key fob. The key fob is the most common component of the immobiliser system to fail. This can be due to a number of factors, such as a dead battery, water damage, or wear and tear.
  • Faulty immobiliser unit. The immobiliser unit is the electronic control unit that controls the immobiliser system. It can fail due to a number of factors, such as a short circuit, water damage or a software glitch.
  • Faulty ignition ring. The ignition ring is a metal ring that surrounds the ignition lock cylinder. It contains a transponder chip that communicates with the key fob. The ignition ring can fail due to a number of factors, such as wear and tear, corrosion or damage.
  • Faulty ECU. The ECU is the main computer in your car. It controls all of the car’s electronic systems, including the immobiliser system. The ECU can fail due to a number of factors, such as a short circuit, water damage or a software glitch.

How to prevent immobiliser problems

There are a few things you can do to prevent immobiliser problems:

  • Keep your key fob batteries fresh. Replace the batteries in your key fob regularly, even if you don’t think they are dead.
  • Avoid getting your key fob wet. If you do get your key fob wet, dry it off immediately.
  • Don’t leave your key fob in direct sunlight or in hot environments. This can damage the battery and electronic components in the key fob.
  • Have your immobiliser system serviced regularly. A Volkswagen specialist can inspect your immobiliser system for any signs of wear or tear and they can fix any problems before they cause your car to break down.

If you have any concerns about your Volkswagen’s immobiliser system, please do not hesitate to contact Volksmaster. We will be able to diagnose and repair any problems quickly and efficiently.

  • If your car has a separate key for the ignition and the doors, try using the ignition key to unlock the doors. This can sometimes reset the immobiliser.
  • If you have a spare key fob, try programming it to your car. This can sometimes fix immobiliser problems caused by a faulty key fob.
  • If you have recently had your car serviced, check to make sure that the mechanic did not disconnect or damage any of the immobiliser system components.
  • If you are locked out of your car, you can use the key in the hidden keyhole in your car door to gain access manually. Remove the plastic cover carefully to access the keyhole.
