Reprogramming Car Keys

Transponder keys are believed to be more secure for cars and harder to copy by thieves. However, a key might need to be reprogrammed if it becomes damaged or lost.

You can program key fobs yourself but you must be aware of the proper procedure. It is essential to have these items to achieve the most effective results:

Keys

Most modern vehicles require some kind of transponder fob or transponder keys to operate, providing security and protection against theft. These keys are programmed by a locksmith or authorized dealer to work with the car's systems and the specific model. They can be costly to replace if they are lost therefore, it is recommended to keep spare keys in the car. You can purchase key fobs that can be replaced in online stores and many brick and mortar auto shops. How can you know that the one you bought is authentic? Are you able to tell whether it has been programmed for a different vehicle or if it could be reprogrammed for yours?

To program a new car key you must first verify that your vehicle is running. Insert the key that you want to program into the ignition, but do not turn it. There are only a couple of seconds before the car's system resets commands and exits programming keys mode. Therefore, it is important to move quickly and not be able to wait between steps. Stop the engine to prevent this. Turn the key from "on" to "off" to test the system. You should hear a chime signalling that the procedure was successful. The door locks will cycle.

Certain newer vehicles have rolling key technology, which prevents thieves from using a stolen vehicle's key to start it. This feature is still susceptible to a technique dubbed replay attack. It allows thieves to record and later reproduce the signal from the vehicle key fob to open the car. To counter this, manufacturers have introduced a security feature called the CAN bus protocol to stop attacks on hacking.

Certain manufacturers have a unique encryption on their keys that cannot be decoded by an ordinary program. You should only try this process if your experience is with electronic devices. It's a good idea to read your car's owner manual or look up the manufacturer online, as these steps vary by vehicle type.

Transponder chips

Car keys with transponder chips require a special programming to function. While any hardware store can cut a new key for you, the real issue is how to integrate it in conjunction with your particular car. The key has to be programmed to match the exact identification number of your car, otherwise it won't start.

Transponder chips are a standard feature in modern cars and are designed to guard against car theft. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is put in. The car then scans for the signal and then starts the engine if it matches the original signal that was programmed into the vehicle. The car is also programmed so that it will shut down if it detects an invalid frequency. This makes it more difficult for novice car thieves to connect a vehicle with hot wires and start it.

A circuit board that has an induction coil connects the key to the chip. When the key is placed in the ignition, a magnetic field is 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 sent back to the vehicle, and if it is in line with the engine will begin to run.

There are many ways to program a key transponder, however all require an instrument that is specifically designed for. You can buy these tools online or from most locksmiths for cars. They are not cheap, but they are crucial for programming the chip in your car.

You could also use a reprogrammable key that was previously programmed for another vehicle. In this case you'll need sure that the key isn't damaged or the transponder has been altered in any way. You can read the chip with a scanner, or a computer equipped with an USB connector.

Reprogramming an transponder's key is easy, but it will require special software and a scanning tool. It's best to ask an auto locksmith for assistance for those who are new to the process. You should also avoid buying secondhand keys, as they're likely to be programmed and won't work with your car.
