Reprogramming Car Keys

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

You can reprogram key fobs yourself, but you must know the proper procedure. For the best results, you should have the following items:

Keys

Modern cars require a transponder key in order to operate. This provides security and anti-theft protection. These keys must be programmed to your particular car and its systems by an authorized dealer or locksmith. It is expensive to replace them if they are lost, so it's a good idea to have spares in your possession. You can purchase key fobs to replace them in online stores as well as many brick and mortar auto shops. How can you be sure that the one you purchased is genuine? Can you tell whether the unit is programmed to work with a different vehicle or if yours can be reprogrammed?

If you are planning to program an entirely new key first, you need to ensure that your car is running. Insert the key you want to program into the ignition, but don't turn it. There are only just a few seconds before the car's system resets commands and leaves programming mode. Therefore, it is important to be quick and not pause between steps. Shut off the engine to avoid this. You can test the car's system by turning the key to the "on" position and back to the "off" position. You should hear a chime to indicate that the process was successful. The door locks will be able to cycle.

Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to start the vehicle. The technology is still susceptible to a technique dubbed a replay attack that allows thieves to record the signal received from the key fob of the car and then replicate it to open the car. To stop this, manufacturers introduced a security feature known as the CAN bus protocols to stop hackers from gaining access to the vehicle.

Certain manufacturers also employ special encryption on their key fobs that cannot be decoded with an ordinary program. These types of cars require programming by a professional, so you should only attempt this process if you have experience working with electronic devices. Refer to the manual for your car or look up the website of the manufacturer for information on how to program it. The steps will vary depending on the model of vehicle.

Transponder chips

Car keys with transponder chips require a specific reprogramming to function. While any hardware store can cut a new key for you, the main issue is how to integrate it to work with the specific car you own. A key that has been reprogrammed will need to be matched with the exact identification number of your car otherwise it won't even start the engine.

Transponder chips, which are used to prevent car theft, are a common feature of modern cars. The chip is a tiny microcircuit which transmits a radio-frequency signal when the ignition key is put in. The car then recognizes the signal and then starts the engine if it is in line with the original frequency that was programmed into the vehicle. The car is also programmed to shut down when it detects an incorrect frequency. This makes it much more difficult for thieves who are not experienced to hot wire a vehicle and then start it.

A circuit board with an induction coil connects the key to the chip. When the key is inserted into the ignition it creates an electromagnetic field around the transponder. This creates a signal which is received by the coil before being sent to the key's identification number. The key's ID number is transmitted back to the vehicle, and if it is in line with the engine will begin to run.

There are several methods to program a key transponder, however all require an instrument that is specifically designed for. You can buy these tools on the internet or at many locksmiths in the automotive industry. These tools are not expensive, but they are essential for programming the chip in your car.

You could also use a resettable key that was programmed for a different vehicle. In this case you'll need sure that the key isn't damaged or that the transponder has been altered in any way. You can read the chip by using a scanner or a computer that has a USB connector.
