why Would You want to remove Immobilizer
In that note let me point out some reasons why you might want to remove 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 it 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 and advanced auto security system not to work is a dead key fob battery. Your key fob is used to send 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 case you can just easily change the key fob battery and continue using your car or you can still remove engine immobilizer. In the case where the system is an old fashion and you will want it upgraded, you can option for the removal of the old security system too.
What causes Immobilizer problem?
The major and most common cause of immobilizer problem is in the car key fob. The key fob is used to send 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 along to start the car. The key fob depends greatly on the battery to be able to send small wave signal to the system transponder. If the battery it 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 have problems, in 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. The wiring harness can as well get damaged due to accidents or so. If this is the case you your car, the best option is to remove engine immobilizer, if not your car won’t start.
- 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. This signs are the same as the symptoms that the system puts up to tell you 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 engine immobilizer from your car….
- Difficulty in starting the car Generally, when vehicle security systems starts 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 surfer major damage due to corrosion as a result of water and moisture if finds it 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 a professional help to trace the problem. Whatever the cause may be please weigh the consequences before you take actions.
- 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 check your key fob battery to be sure it is correctly installed and okay. If it passes that check and the door is till been difficult to open and close, then consider visiting a professional auto lock smit 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 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.

The researchers at the Chaos Communication Congress presented a paper about the reliability of modern vehicle inmobilization systems. In the Netherlands vehicle theft dropped by up to 80 percent between 1995 and 2008.
However, immobilizers are as easily cracked as any other relatively complex technology. Cybersecurity researcher Wouter Bokslag chooses this as the topic of his Master’s thesis and presents his results at the36th Chaos Comm ciprs. They have been compiled by researchers Jan C. van Ours and Ben Vollaard.
