Immobilizer car with a key warning light

Immobilizer car with a key warning light comes on if your anti-theft system doesn’t sense the car key being used, or if it’s registering low battery power.

This prevents the engine from starting, even if the key is turned. The light will usually come on when the key is first inserted into the ignition, and will go out after a few seconds. If it stays on, or comes on while the engine is running, it means that there is a problem with the immobilizer system.

What is an engine immobilizer?

An engine immobilizer is an electronic device fitted to a vehicle which prevents the engine from running unless the correct key is present. It’s a theft prevention measure which works by storing a key’s transponder information in the car’s computer, and only allowing the engine to start if it detects the right transponder signal.

Its function is to prevent a car from being hot-wired and stolen by a criminal who lacks the necessary keys to start the engine.

How does a car immobilizer operate?

The engine immobilizer is a security device that is fitted into the ignition system of a car. It works by storing a code in the car’s computer which corresponds to the transponder chip in the key. When the key is used to start the car, the code is read and if it matches, the car will start. If the code does not match, the car will not start.

Problems with locking a car

When you use a key to remotely lock your vehicle’s doors, you will notice that they do not lock. It’s a solid indicator that your car’s immobilizer isn’t working properly. Many modern automobiles lack outside keyholes, making it hard to unlock the doors manually with the key.

Difficulty to starting the car

Additionally, if your car does not start when you turn the key, or if it takes longer than usual for your car to start, these may also be signs of a bad immobilizer.

Problems with unlocking a car

Key does not turn when it is in ignition

If your key fob contains a physical key that you must place into the ignition and crank and it does not move, the transponder chip within the key fob base may be faulty. It is not delivering the security code to the auto immobilizer for some reason.

This is often due to water damage (water + electronics do not mix) or real chip failure as a result of the fob falling or being crushed.

Car alarm issues

If the car alarm goes off for no reason, it is a sign that your immobilizer system is not working properly. A car alarm going off intermittently or randomly is another sign of trouble.
