Keys

Nearly all modern vehicles require some kind of transponder key or fob in order to operate, providing security and protection against theft. The keys have to be programmed to your particular car and its systems by a certified locksmith or dealer. They are costly to replace if they are lost, so you should have spares in your car. You can locate replacement key fobs in online stores, as well as many brick-and mortar auto shops. But how do you know that the new key fob you bought is genuine? Can you tell whether the unit is programmed to work with a different vehicle or if yours can be programmed differently?

To program car keys a new car key you must first ensure that your car is running. Insert the key you wish to program into the ignition without turning it. There are only a few seconds left before the system resets all commands and exits the programming mode. For this reason, it is important to move fast and not pause between steps. To avoid this happening, shut off the engine. Change the key from "on" to "off" to test the system. 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 open the car. The feature is still vulnerable to a technique known as replay attack. It allows thieves to record and reproduce the signal from the vehicle key fob to open the car. To stop this, manufacturers introduced the security feature known as the CAN bus protocols to prevent hacking.

Certain manufacturers also have special encryption on their key fobs, which are not decoded by a simple program. It is best to only attempt this method if your previous experience is with electronics. It is recommended to consult the owner's manual for your car or look up the manufacturer on the internet, since these steps vary by vehicle model.

Transponder chips

Car keys with transponder chips require a special reprogramming to work. Any hardware store can offer you a new car key but the real challenge lies in implementing it to your car. The key has to be programmed to match the exact identification number on your vehicle, or else it won't start.

Transponder chips are a common feature of modern cars and are designed to prevent car theft. The chip is a microcircuit which transmits a radio frequency signal when the key is put in the ignition. The car detects the signal and begins the engine only if it matches the original that was programmed into the vehicle. The car is also programmed so that it will stop when it detects an incorrect frequency. This makes it much harder for car thieves with no experience to wire a vehicle and then start it.

The key and the chip are connected by the circuit board which includes an induction coil. When the key is placed in the ignition, it creates a magnetic field around the transponder. This generates a signal that is absorbed by the coil and then transmitted to the key identification number. The key's ID number is then sent back to the vehicle, and if it matches, the engine will start.

There are several ways to program a transponder key, however, all require a special tool. You can buy these tools online or from most automotive locksmiths. These tools are not expensive, but they are essential for programming the chip in your car.
