The keys are programmed by a locksmith or an authorized dealer to work with the car's systems and reprogramming car keys the specific model. It's costly to replace them if they become lost, so it's a good idea to keep extras on hand. You can also find replacement keys fobs at various online stores and in many brick-and-mortar auto shops. How can you know that the key you purchased is authentic? Are you able to tell whether the unit has been programmed to work with a different vehicle or if it could be reprogrammed?

To program a new car key, you must first ensure that your vehicle is running. Insert the key you want to reprogram into the ignition without turning it. You have only a few seconds before the system will reset all commands and exits the programming mode. It is essential to be quick and don't be patient between each step. To prevent this from happening, turn off the engine. Change the key from "on" to "off" to test the system. You should hear a chime signalling that the procedure was successful.

Transponder chips

programing car keys keys with transponder chips require special reprogramming in order to function.

Transponder chips, used to prevent car theft are a standard feature of modern cars. The chip is a tiny microcircuit which transmits a radio-frequency signal when the ignition key is inserted. The car then detects the signal and begins the engine if it is in line with the original one that was programmed into the vehicle. The car is also programmed to stop when it detects an incompatible frequency. This makes it much harder for thieves who are not experienced to hot wire a vehicle and then start it.

A circuit board with an induction coil connects the key to the chip. When the key is placed in the ignition it creates an electric field around the transponder. This generates a signal that gets amplified by the coil which then transmits it to key's identification number. The key's identification code is returned to the car, and the engine starts when the identification number matches.
