Reprogramming Car Keys

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

You can program key fobs yourself but you must be aware of the correct procedure. To get the best results, you must have the following items:

Keys

Nearly all modern vehicles require a transponder key or fob in order to operate, ensuring security and protection against theft. The keys are programmed by a locksmith or an authorized dealer to function with the car's systems and specific model. They are costly to replace if they are lost and it is recommended to keep spare keys in the car. You can purchase key fobs to replace them in online stores, as well as many brick-and mortar auto shops. But how do you know that the one you purchased is authentic? Are you able to tell if the unit has been programmed to work with a different vehicle or if yours can be programmed again?

If you are planning to program a new key, the first step is to ensure that your vehicle is on and running. Insert the key that you'd like to program into the ignition, but do not turn it. There are only a few seconds before the car's system resets the commands and then exits programming mode. It is important that you move quickly and don't be patient between each step. To prevent this from happening, shut off the engine. You can check the system of your car by turning the key to the "on" position, then back to the "off" position. You should hear a sound indicating that the process was successful. The door locks will be able to cycle.

Some newer vehicles use rolling keys to keep thieves from using stolen keys to open the vehicle. This feature is still susceptible to a technique called a replay attack. It allows thieves to record and then reproduce the signal received from the vehicle key fob to unlock the car. To prevent this, manufacturers have added the security feature known as the CAN bus protocols to ward off hackers from gaining access to the vehicle.

Certain manufacturers also have special encryption on their key fobs, which are not decoded by a simple program.

Transponder chips

Car keys that feature transponder chips require special reprogramming to work. While any hardware store can cut keys for you, the biggest issue is how to integrate it with your specific car. The key needs to be programmed to match the exact identification code on your car, or else it won't start.

Transponder chips are a common feature in modern cars and are designed to stop car theft. The chip is a microcircuit which emits a radio frequency signal when the key is inserted into the ignition. The car keys programming detects the signal, and starts the engine only if the signal is in line with the original that was programmed into the vehicle. The vehicle is also programmed to stop when it detects an incorrect frequency. This makes it difficult for thieves who aren't experienced to wire a vehicle hot and then start it.

A circuit board equipped with an induction coil 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 and sent to the key identification number. The key's ID number is then sent back to the vehicle and if it matches the engine will begin to run.

You can purchase these tools online or from most locksmiths in the automotive industry. They're not cheap, but they are vital for programming the chip into your car.

The process of reprogramming an transponder's key is easy, but it will require specialized software and a scan tool. It's best to ask an auto locksmith for help in case you're not an expert. Avoid buying used keys as they may already be programmed, and they won't work with your car.
