Transponder Key Programming
The transponder is a vehicle security idea born in 1995 and has since then overtaken the concept of identification in personal and commercial vehicles. If you own a car manufactured after the 1990s, it is most likely equipped with a transponder key and a receiver in the car too.
If any other key but this transponder key is inserted in the ignition of your car, it will fail to start. This is because only that key can disarm the immobilizer in your vehicle. However duplicates can be made. Without disarming your immobilizer, your car will not move. So, it doesn’t make sense to have only one of such powerful keys.
How then do you program a transponder key if you just got one? Or maybe you bought a new transponder key and got it cut, how do you program it to be used in your car?
