This post is confusing, correct me if i am wrong please i am a newbie.
There is two types of programming.
1. For the key to lock and unlock the doors.
2. For the key to start the car.

so from what i understand, you can reprogram any key to unlock/lock the doors for any vehicle, but once a key has been programmed once to a car in order for it to start, it can not be reprogrammed to another vehicle.

Is this correct?
