Lost spare key for Buick Escalade

First, the chip in the spare key can be disabled, but if someone else picks up the key, without starting the car, they can use the key to open the door or trunk, and can steal something from your car. But if you are a professional, you can still start the engine if you unlock it with a connection to the trip computer.

Secondly, the 4S store was able to recode the car without those two things being present, requiring the car to be present.

Third, the 4S store will not be easy to your key code random matching, you are the owner of the car, but also have to ask you out to show the appropriate documents in order to re-match the key, you can rest assured that this point, and match the key and the car computer locks should be the need for the key and the car at the same time present.

Fourth, if you lock the car with the remote control key, and then use the key without a chip to open the door (while the vehicle will sound an alarm), but can not start the car. Because there is a sensor inside the keyhole, if there is no chip on the key, it will not be able to unlock the electronic lock and thus start the vehicle. But if you are using the key to twist to lock the door, instead of using the remote control, then the trouble is big.
