Car keys with transponders are thought to keep vehicles safer and are harder for thieves to duplicate. The key could need to be reprogrammed in the event that it is damaged or lost.

Keys

Most modern cars require a transponder keys to operate. This gives security and protection against theft. The keys must be programmed to the specific vehicle and its features by a licensed dealer or locksmith. They are costly to replace if lost therefore, you should keep extras handy. You will also find replacement key fobs at various online stores and in many brick-and-mortar auto shops. How can you know that the key you purchased is genuine? Do you know if the unit has been programmed to work with another vehicle, or if it can be reprogrammed?

If you want to program an entirely new key first, you need to ensure that your vehicle is operating. Insert the key that you want to reprogramme into the ignition, but do not turn it. There are only a few seconds before the car's system resets the commands and leaves programming mode. Therefore, it is important to move quickly and not wait between steps. Turn off the engine to stop this. Switch the key from "on" to "off" to test the system. You should hear a chime to indicate that the process was successful. The door locks will cycle.

Some newer cars use a rolling key technology, which keeps thieves from using a stolen vehicle's key to open it. The technology is still susceptible to a technique known as replay attack that allows thieves to record the signal of the key fob on the vehicle and reproduce it later to unlock the car. To combat this, manufacturers have added security features known as the CAN bus protocols to ward off hacking.

Certain manufacturers also have special encryption on their key fobs, which cannot be decoded by an easy program. You should only try this process if your experience is in electronics. Refer to the manual for your car or visit the website of the manufacturer to find out how to program it. The steps to follow will differ according to the type of vehicle.

Transponder chips

Any hardware store can give you an entirely new car key, but the real challenge is in integrating it with your vehicle. The key must be programmed to match the exact identification number on your vehicle, or else it won't be able to start.

Transponder chips, which are used to stop theft of cars are a standard feature of modern automobiles. The chip is a microcircuit that transmits a radio-frequency signal when the ignition key is put in. The car then scans for the signal and starts the engine if it matches the original signal that was programmed into the vehicle. The car is also programmed so that it will stop if it detects an invalid frequency. This makes it harder for thieves with no experience to connect a vehicle to a hot wire and then start it.

A circuit board that has an induction coil that connects the key to the chip. When the key is inserted into the ignition, it creates an electric field around the transponder. This generates a signal, which is absorbed by the coil before being sent 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 start.
