As time went on and technology improved as it did, automobile manufacturers began to combine physical and electronic protocols to protect against theft. These key systems are called transponder keys or chip keys and they're designed to make it difficult for thieves to get into the vehicle.

The mobile key programming near me chips inside the keys have a specific serial number, which transmits a signal to the receiver inside of your car. When the signal is received it is compared to an existing code in the car's computer. If the codes match, then the car will start. If not, it will not start at all. This is one of the primary reasons you should keep a spare key in your vehicle, particularly if you have an electronic transponder.
