The car transponder key first started being used in the 1990s. These keys are programmed to send electronic messages to your ignition. The Electronic Control Unit (ECU) in your car communicates with the transponder. When you put the key in the ignition, when programmed correctly, it sends a message letting the car know it is okay to start up.
Transponder key programming is a big deal for most people. Every car is different when it comes to programming a transponder chip, and unless it is programmed correctly, your car key will not be able to start your car.
That’s why in addition to cutting and replacing your key, our locksmiths will also program them for you. You can count on us to ensure that all you have to worry about is turning the key in the ignition and driving home.
Many manufacturers have started placing transponder chips in the plastic part of the car key. This technology has played a part in cutting down on auto theft. Many thieves rely on fake or “bump” keys to unlock cars and start the ignition, but because transponder chip keys need to be programmed, fake keys will not work.
Auto transponder keys are extremely common. If your car was made after 1995, you most likely have one. Usually, you can tell if you have one if the plastic portion of your key is thick. Also, if you wrap the plastic in foil and try to start your car, it should not start.
Transponder key cutting needs to be extremely precise. Also, these keys need to be programmed before they are able to start your engine. At Tucson Locksmith, we have employed numerous trained professionals to ensure that you will get a quality car key every time you count on us.
