Keys

The majority of modern vehicles require a transponder key in order to operate. This gives security and protection against theft. The keys are programmed by a locksmith or authorized dealer to function with your car's system and the specific model. They are expensive to replace if they are lost and it is recommended to keep spare keys in the car. 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 one you purchased is authentic? Do you know whether the unit has been programmed to work with a different vehicle, or if it can be programmed again?

If you want to program an entirely new key, the first step is to make sure that your car is running. Insert the key that you want to reprogramme into the ignition, but don't turn it. You only have a few seconds before the car key programmers's system resets commands and exits programming mode. For this reason, it is essential to be quick and not be able to wait between steps. Stop the engine to avoid this. You can check the system of your car by turning the key to the "on" position, then back to the "off" position.

It allows thieves to record and later duplicate the signal generated by the vehicle key fob to open the car.

The car then detects the signal and starts the engine if it matches 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 car thieves with no experience to hot wire a vehicle and then start it.

The key and the chip are connected via the circuit board which includes an induction coil. When the key is put in the ignition it creates a magnetic field generated around the transponder. This creates a signal which is received by the coil and then transmitted to the key's identification number. The key's ID number is sent back to the vehicle and if it is in line with the engine will start.
