Keys

Nearly all modern vehicles require some kind of transponder key or fob to work, which provides security and protection against theft. These keys must be programmed to your specific car and its systems by a licensed dealer or locksmith. It is expensive to replace them if they are lost, so it's better to keep extras on hand. You can also find replacement key fobs on various websites and in many brick-and mortar auto shops. How can you ensure that the one you bought is authentic?

To program a new car key, you must first ensure that your vehicle is running. Insert the key that you want to program into the ignition, but don't turn it. You will only have a few seconds before the car's system reverts the commands and exits programming mode. For this reason, it is important to be quick and not be able to wait between steps. To avoid this happening, shut off the engine. Switch the key from "on" to "off" to test the system. You should hear a sound signalling that the procedure was successful.

Some newer vehicles use rolling keys to keep thieves from using stolen keys to open the vehicle.

Transponder chips

Car keys with transponder chips need special reprogramming to work. Any hardware store can make you an entirely new car key, but the real challenge is in integrating it with your car. The key must be programmed to match the exact identification code on your car, otherwise it will not start.

Transponder chips are a typical feature in modern cars and are designed to stop car theft. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is put in. The car detects the signal, and starts the engine only if the signal matches the one programmed into the vehicle. The vehicle is also programmed to stop when it detects an incompatible frequency. This makes it more difficult for novice car thefts to connect a vehicle to a hot wire and then turn it on.

A circuit board with an induction coil that connects the key to the chip. When the key is placed in the ignition the magnetic field is generated around the transponder. This creates a signal which is absorbed by the coil and then transmitted to the key identification number. The key's identification number is sent back to the car key cutting and programming and the engine is started if the identification number matches.
