Learn how to remove engine immobilizer. To remove the engine immobilizer, first, unscrew the steering wheel cover under the dashboard and trace it to the ignition switch and remove it. Once removed the car would start without needing to worry about the immobilizer causing any difficulty. 

An engine immobilizer is an electronic security system used in most modern-day cars to reduce the rate of theft. It prevents the vehicle from being “hot wired” after entry has been achieved and thus reduces motor vehicle theft. The primary function of an immobilizer is to prevent the engine from starting without using the vehicle’s authorized key.

 

How to Remove Engine Immobilizer

 

To remove the immobilizer, Insert the key into the ignition and turn it to the on position, which activates your accessories but not the engine. Leave the key in position for about 10 – 15 minutes. Check the anti-theft light again. If it’s no longer blinking, turn the key back to the Off position and allow it to sit for a minute or two.

Immobilizers add an extra layer of security to you in such a way that only the original key will be able to start the car. In some advanced vehicle security systems, the system will put up an emergency lock if attempted to bypass.

How to Remove Immobilizer from Ecu

 

The engine control unit (ECU) also called the brainbox, controls the ignition and also oversees the activities going on in the car’s engine. An immobilizer is designed to cut communication between the immobilizer and the car ignition.

To remove the immobilizer from the ECU, open the steering wheel cover under the dashboard. Now look for the immobilizer LED light, trace the wire to the ignition switch wire dongle that leads to the ECU, and cut off the two wires connecting the immobilizer to the system.

Tracing the wire can be difficult sometimes because it might have been rapped in plenty of duct tape in an effort to disguise and keep it hidden. Just take all the time you need and carefully unwrap the tape until you can reach the wires.

Reasons to Remove Immobilizers From Your Car

 

On that note let me point out some reasons why you might want to remove the engine immobilizer from your car. Over the years and due to vehicular usage, the system could get damaged due to moisture or water.

  • Corrosion will be the result if moisture or water finds its way into the system and corrosion is not good for the connectors and wire harness. When wires and connections get corroded current fails to flow which can lead to the immobilizer system from working.
  • Another thing that can cause an advanced auto security system not to work is a dead key fob battery. Your key fob is used to send the dedicated key token to the transponder in your car, if the battery is dead or depleted it will not be able to send the signal correctly.

 

 

In such a case, you can just easily change the key fob battery and continue using your car or you can still remove the engine immobilizer. In the case where the system is an old fashion and you will want it upgraded, you can opt for the removal of the old security system too.

 

What causes Immobilizer problem?

 

The major and most common cause of immobilizer problems is in the car key fob. The key fob is used to send a signal to the car security transponder which in turn temporarily disables the system.

Dead key fob battery:- If you have tried all your can and your car would not still start then you should check the key fob’s battery. The battery could be dead and it could be the reason why your car is not recognizing the key let alone starting the car.

The key fob depends greatly on the battery to be able to send a small wave signal to the system transponder. If the battery is dead then the key fob will not be able to send the required signal to the transponder to disarm the system.

Damaged or corroded wire connection:- The immobilizer system itself barely has problems, in a worst-case scenario, the system wires can get corroded due to water damage. Due to day to day activities, the immobilizer wiring connection can become corroded.

If the actual immobilizer system in the vehicle is to blame, then it could be due to the wires being corroded or damaged. Perhaps the engine control unit or its sensors are malfunctioning or faulty.

 

How to Boost Performance With Immobiliser

 

We all want our car to run at optimal levels, but what you might not know is that there are a few simple things you can do to make sure your car is running at its best.

In the present era, the right immobilizer has been introduced to make sure that cars are secure from theft. They vary from keyless entry systems in which a keypad with a numerical code is used instead of a physical key.

Immobilizers in cars have been in use for decades and have proven to be an excellent deterrent against car theft.

The main advantage of an immobilizer is that it cannot be accessed by another person without the permission of the owner.

Common Symptoms of bad engine Immobilizer

 

Just like most other parts of your car, the engine immobilizer does not just stop working once. The system starts to show some signs of malfunctions that indicates that something is wrong really.

 

 

These signs are the same as the symptoms that the system puts up to tell the car owner or driver that something is wrong and needs to be checked. Some of these signs and symptoms would determine whether or not to remove the engine immobilizer from your car.

  • Difficulty in starting the car

Generally, when vehicle security systems start to develop problems difficulty in starting is a common challenge. This issue can be localized to the engine immobilizer in most cases.

The immobilizer can suffer major damage due to corrosion as a result of water and moisture if finds its way through the wiring. This can cause the immobilizer to malfunction thereby making it difficult and sometimes impossible to start the car.

If you find yourself in this shoe, the options are either you remove the immobilizer, or you call for professional help to trace the problem. Whatever the cause may be please weigh the consequences before you take action.

  • Door Locking and unlocking Problems

This is another problem that could be some times traced to auto security systems. The door is said to become unstable and difficult to open and lock at a go.

If you are experiencing this, you might want to want to check your key fob battery to be sure it is correctly installed and okay. If it passes that check and the door is still been difficult to open and close, then consider visiting a professional auto locksmith for help.

  • Key in Ignition Does Not Turn

If your key fob has a physical key that you must insert into the ignition and turn and it doesn’t budge, you may have a problem with the transponder chip inside the key fob base. For some reason, it’s not sending the security code to the car immobilizer.

This is often due to water damage (water + electronics don’t mix) or actual breakage of the chip due to the fob falling or being crushed. Before ordering a replacement key, make sure you’re using the correct key fob for the car. Just because your spouse drives the same make of car doesn’t mean her key fob will work in yours.

  • Car Alarm Problems

The alarm system in your vehicle is associated with the same security feature as your immobilizer. If you have a bad immobilizer, then you’ll likely have a bad alarm system too.

Depending on the type of alarm system that you have installed, this means anyone breaking your windows or stepping near your vehicle will no longer cause the alarm to go off.

Conclusion

An engine immobilizer is an anti-theft system built in the engine ECU. It can better be seen as an electronic security device fitted to a motor vehicle that prevents the engine from running unless the correct key (transponder or smart key) is present.

This system has been a very good improvement in auto security ever since it was invented. However, the system has its shortcoming and causes difficulty in starting the car if it is faulty or unauthorized access have been attempted.
