Keys

The majority of modern vehicles require a transponder key in order to operate. This is a security feature and protection against theft. These keys are programmed by a locksmith or authorized dealer to work with your car's systems and specific model. They are expensive to replace in the event of loss, so you should keep extras handy. You can also find replacement keys fobs in various online stores and in many brick-and-mortar auto shops. How can you know that the key you purchased is genuine?

Transponder chips, which are used to prevent car theft, are a common feature of modern cars. The chip is a microcircuit that emits a radio frequency signal when the ignition key is inserted.

The car is also programmed to stop when it detects an incompatible frequency. This makes it difficult for thieves who aren't experienced to hot-wire a vehicle and then turn it on.

The key and the chip are linked by a circuit board that includes an induction coil. When the key is placed in the ignition it creates an electromagnetic field around the transponder. This creates a signal which is absorbed by the coil and sent to the key identification number. The key's identification number is returned to the car, and the engine starts when the identification number matches.
