Transponder Chips Transponder chips are used in a lot of modern cars to guard against theft of vehicles. These are small computer microchips which emit radio signals of low-level. They have a unique serial number which authenticates your key when you connect it to the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down.

It is more complicated and requires an in-depth understanding of how electronic systems operate. This is why it should be left to a professional who has a lot of experience working on these types of systems. Onboard programming is the fastest method for locksmiths to program a new key. It can take less than an hour if everything is completed correctly. However, if the key isn't in the correct situation or the procedure isn't strictly followed, it could take up to an hour. There are many different key programmer scanners that support different models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both very popular amongst locksmiths because they can be used with a variety of vehicles. No system can program every vehicle.
