Transponder Chip Car Keys Cost More – What’s That All About?
Have you ever scratched your head, wondering why your car key replacement costs more than the regular locksmith job?
It’s for your car’s extra security.
Most car models in the market now use what we call transponder, or chip, keys that needs to be programmed. These car key transponders were implemented by car manufacturers to lessen the risk of car theft, which eventually became an issue with the insurance companies back in the 1990s. But the technology dates back to World War II, to identify friendly planes. And they
are also used in modern aviation.
Before the chip keys, carmakers and locksmiths only had to make sure the keys are cut to fit your locks and ignition. With transponder keys, not only does it have to fit, the keys have to be programmed to respond correctly to disarm the car’s immobilizer system in order to start it.
How does it work?
The head of the car key has a transponder chip that emits a low-level signal that will be detected by a receiver around the ignition cylinder. Once you turn the key, coded signals will be exchanged and the computer authenticates the response if it is the car’s real key. This significantly reduced the incidence of stealing cars by hot-wiring or using duplicate keys, as the car will not start if it doesn’t receive the correct response from the correct auto transponder key.
Programming the transponder key.
Without the proper programming, a transponder key will not be able to start your car. The key will still be able to open your car door and trunks though.
Each car model has its own programming method, so it can be pretty tricky. But it only takes a few minutes and it can be done with just the keys, or at the car itself. In some cases, the procedure is longer because some machines are built-in with authentication period or there is a waiting time.
For transponder car key replacements and programming, the key must be blank – no cuts and no programming done on it yet. Be careful of secondhand keys because it is almost impossible to recut it and you cannot reprogram it for another car.
