Frequently Asked Questions – BMW 640i GT 6 Series

How much does a BMW 640i GT 6 Series key replacement cost in San Antonio?

What type of key does the BMW 640i GT 6 Series use?

The BMW 640i GT 6 Series uses a key fob that communicates with the vehicle’s CAS4 immobilizer system. The key must be properly cut and electronically programmed to match your vehicle’s security module before it will start the engine.
