From the 80-90’s vehicles are equipped with anti-theft technologies. These technologies protect the car from being started without the proper key. Most of the time separate modules or ECUs are connected to the Engine control unit to be able to run the engine. These modules or ECUs can be unpleasant when building the engine into a boat, other car or race/track car.

Karreman Engineering offers a service to disable the functionality of the immobilizer. With the removal of its functionality it is no longer necessary to use the modules or ECUs attached to the Engine Control Unit to operate or start the engine.

Besides the deletation or disabling of your immobilizer Karreman Engineering offers new keys, replacement electronics inside the key and new push buttons to make your key like new. These items can be seen in the webshop.
An example is a new key for your BMW E46 3 series (1998-2005). A genuine key will cost €160,- (NL) ex. VAT.

Karreman Engineering can offer the same key for €100,- . How this is possible? Like other parts on a car can be made by different manufacturers keys can be made by other manufacturers. The chips inside are used among many other manufacturers and widely available. The same applies for the remote control for central door locking electronics. Eventually the shell and key blade have to be made which is possible with today’s techniques.
