There are two kinds of car locks, one is to replace the whole car lock, which will be more expensive, and it takes a long time, and the other is that you can not replace the whole car lock, you only need to change the door lock cylinder and ignition lock cylinder, which is the so-called tooth change, and the effect of replacing the whole car lock is the same, of course, it is much cheaper. Moreover, the car lock treasure should also be able to disable the remote control key used by the vehicle before, so that the previous key of the vehicle can not be used to open the door with the previous remote control.
