Reprogramming Car Keys

Transponder keys are thought to be more secure for vehicles and more difficult to copy by thieves. However, a key may need to be reset if it becomes damaged or lost.

You can change the programming of your key fobs at home, however you must know the right process. For the best results you must have the following items:

Keys

Modern cars require a transponder key to operate. This provides security and anti-theft protection. The keys have to be programmed to the specific vehicle and its systems by a certified locksmith or dealer. It's expensive to replace them if they become lost, so it's a good idea to keep extras on hand. You can also find replacement key fobs in various online stores and in a variety of brick-and-mortar automotive shops. How can you ensure that the one you purchased is genuine? Do you know if the unit has been programmed to work with another vehicle, or if it can be programmed differently?

If you want to program an entirely new key first, you need to make sure that your car is operating. Insert the key you want to program into the ignition, but don't turn it. You only have a few seconds before the car's system resets commands and then exits programming mode. Therefore, it is important to move quickly and not pause between steps. Turn off the engine to avoid this. You can test the system of your car by turning the key to the "on" position, then back to the "off" position. You should hear a chime indicating that the process was successful. The door locks will go through a cycle.

Some newer cars use a rolling key technology, which prevents thieves from using a stolen vehicle's key to start it. This feature is still vulnerable to a technique dubbed replay attack, which allows thieves to record the signal from the key fob on the vehicle and then replicate it to unlock the car. To stop this, manufacturers have added a security feature called the CAN bus protocol to prevent attacks on hacking.

Certain manufacturers also employ special encryption on their key fobs, which are not decoded by an easy program.

The key needs to be programmed to match the exact identification number of your car, or else it won't start.

Transponder chips, used to stop theft of cars are a standard feature of modern automobiles. The chip is a microcircuit that transmits a radio frequency signals when the key is put in the ignition. The car key programmer detects the signal, and starts the engine only if it matches the original that was programmed in the vehicle. The car will also shut down if the frequency is not valid. This makes it much more difficult for car thieves with no experience to connect a vehicle with hot wires and then start it.

A circuit board that has an induction coil connects the key to the chip. When the key is put in the ignition it creates a magnetic field generated around the transponder. This produces a signal which gets absorbed by the coil, which then transmits it to key's identification number. The ID number of the key is then sent back to the vehicle, and if it matches the engine will begin to run.
