Immobiliser Repair - Replacement

Software Update


BMW's manufactured before 2009 which didn't have their immobiliser modules updated with the newest software can have a new car key programmed directly through the OBD Port which makes them easy to steal.


Software Updates is one of the ways you can reduce the risk of your BMW being stolen. With the latest update,To program a key to the vehicle where no keys are present it's not possible without taking out any modules. This drastically improves the security of your vehicle.

CAS Replacement

  • Vehicle not starting with an immobiliser warning light

  • Lack of communication with the immobiliser module

  • Water damage to the immobiliser unit

  • Vehicle not starting - Key not recognised

Most workshops or dealership are not capable of replacing the module with a second-hand donor unit and will advise to either get a new module or a complete immobiliser kit which can become very expensive.


However, some of the faults are easily repaired without the need of replacing the module. When a replacement is necessary, we are able to re-program a second-hand donor unit which will save you quite a lot of money, 

FEM Replacement


Unlike most workshops we're able to unlock and program a used second hand FEM or BDC Immobiliser module. We can accomplish this by transferring over data from the original module to the donor module. 

In the event of fire damage to the FEM or the BDC module where the data is impossible to extract or if the module was damaged by inexperienced locksmith during a key programming and the immobiliser data is corrupted. We are also able to program a second hand module into your vehicle by extracting the necessary data out of the car and synchronising all the modules.
