Reprogramming Car Keys

Transponder keys are believed to be more secure for cars and are more difficult to copy by thieves. However, a key might require reprogramming when it becomes damaged or lost.

Keys

Most modern cars require a transponder key to operate. This is a security feature and protection against theft. The keys have to be programmed to the specific vehicle and its features by a licensed locksmith or dealer. They are costly to replace if lost and it is recommended to keep spare keys in the car key programming and cutting. You can find replacement key fobs in online stores, as well as numerous brick-and-mortar auto shops. How can you ensure that the one you purchased is authentic? Can you tell if it has been programmed for a different vehicle or if it is able to be reprogrammed for yours?

If you're looking to program an entirely new key the first step is to ensure that your vehicle is operating. Insert the key you wish to program into the ignition without turning it. There are only a few seconds left before the system will reset all commands and then exits the programming mode. It is crucial to move quickly and do not delay between each step. To avoid this happening, turn off the engine. You can check the car's security system by turning the key to the "on" position, then back to the "off" position. The door locks should cycle and you will hear a chime to indicate that the process has been successful.

Some newer cars use a rolling key technology that stops thieves from using stolen cars' key to open it. This feature is still vulnerable to a technique dubbed a replay attack, which allows thieves to record the signal of the key fob of the car and then replicate it to open the car. To combat this, manufacturers have added the security feature known as the CAN bus protocols to prevent hacking.

Some manufacturers use a special encryption on their keys that cannot be decoded by an ordinary program. You should only try this process if your experience is in electronic devices.

The vehicle is also programmed to stop when it detects an incorrect frequency. This makes it much harder for thieves who are not experienced to connect a vehicle with hot wires and start it.

The chip and the key are connected via an electronic circuit board that contains an induction coil. When the key is put in the ignition, a magnetic field is generated around the transponder. This creates a signal that gets taken up by the coil, which transmits it to the key's identification number. The key's ID number is then sent back to the vehicle and if it is in line with the engine will begin to run.
