More details:
My friend is running car rental company and he need some device which would be able to lock/unlock car using mobile phone (GSM module/BT module/whatever wireless). My idea is use Arduino Uno (or sth similar) and copy the key fob.
Car owner would use his key fob to teach the device and then place it in car.
I'd like to avoid buying programmed key and teaching car the new key. That would be way too complicated for car owners.

Auto locksmiths have those devices and they can charge nominal fee to program car key.
