The BMW immobiliser system is very reliable from the time it has been introduced until this days. The most popular is CAS system covering most cars from 2004 - 2016.
We are offering BMW key replacement for all E and F series cars. Programming the remote fob is performed using highest quality tools in the market. Unlike most locksmith in London we not use china tools. Your new spare key will be made by Autohex 2 or Bmw Explorer most professional and expensive BMW tool in the UK market.
The CAS module is the little box which can be in white or black colour. Cas module response for the synchronisation between many modules in our BMW. First it recognise weather key is correct if so giving the authorisation signal to ECU or gearbox which let us start the car.
Basically if you replace the ECU or CAS or gerabox EGS control module car wont start again without special software synchronisation.
Very important is to update CAS/FEM software which make our BMWs nearly not possible to make the key afterwords.
