As time went on and technology advanced, more and more car manufacturers began blending electronic and physical protocols to stop theft. automotive key programming near me like these also known as transponder keys or chips keys, are designed to make it more difficult for thieves to steal a vehicle.

This energy is absorbed by the chip and it transmits an audio frequency signal that contains an identification code that corresponds with the unique digital serial number that is stored in the car's computer system. This will prevent any unauthorised attempts to start the car as only the correct key will be able to do so.
This technology is believed to be more secure than traditional car keys because it makes it harder for a thief to "hot wire" a vehicle and get it started.
