A.Yes, here is a list of BMW ANTI THEFT (IMMOBILIZER) SYSTEMS 

EWS: "Driveaway Protection System"started as early as 1993.

CAS:"Car Access System"

FEM/BDC:"Front Electronic Module"

Above listed all BMW'S Anti-Theft systems, all of them have the same principal of operation but the programming procedure is different for each and every one.

*Principal of Operation:

A transponder chip is integrated in each of the vehicle keys. A ring coil is fitted about the ignition lock. The transponder chip is powered by this coil. This means that no battery is necessary in the key. The power supply and data transfer take place in the same way as a transformer between the loop antenna (coil) at the ignition lock and the transponder chip.
