Keys

Most modern vehicles require some kind of transponder key or fob in order to work, which provides security and protection against theft. The keys must be programmed to your specific vehicle and its systems by a certified dealer or locksmith. It's expensive to replace them if they are lost, so it's best to have spares in your possession. You can locate key fobs to replace them in online stores and many brick-and mortar auto shops. How do you ensure that the new key fob you bought is authentic? Can you tell whether it was programmed to work with another vehicle or if it is able to be programmed to work with your car?

To program a new car key you must first ensure that your car is running. Insert the key you wish to reprogram into the ignition without turning it. You have just a few minutes before the system resets all commands and exits the programming mode. It is crucial to move quickly and don't delay between each step. Turn off the engine to avoid this. Switch the key from "on" to "off" to test the system. You should hear a sound indicating that the process 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. The feature is still vulnerable to a technique called a replay attack.

Certain manufacturers also employ special encryption on their key fobs, which cannot be decoded by a simple program. These types of vehicles will need to be programmed by a professional, and you should only attempt this procedure with someone who has experience with electronics.

Transponder chips

Transponder chips are a standard feature in modern cars and are designed to guard against car theft. The chip is a microcircuit which transmits a radio frequency signal when the key is put into the ignition. The car then recognizes the signal and begins the engine if it is in line with the original frequency that was programmed into the vehicle. The car key programing is also programmed to stop when it detects an incompatible frequency. This makes it harder for novice car thefts to connect a vehicle to a hot wire and then start it.

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