Transponder Chips


Most modern cars are equipped with what are called transponder chips to stop car theft. These are tiny computer microchips that emit radio waves at a low level. The microchips are equipped with an unique serial number that authenticates your keys when you connect it to the ignition barrel. If your car isn't able to recognize the signal it will shut down the engine. This technology has proved to be an enormous success in preventing auto theft.

The principle of the transponder system is to make it difficult for thieves to start your car without the right key. In the past, car thieves would force your ignition switch to the "on" position using a flat screwdriver or even hot-wire the car to bypass the system completely. Transponder chips have dramatically reduced these types of thefts.

When you insert the transponder keys into the ignition the signal is received by an antenna that is concealed around the barrel. The antenna is programmed to match the frequency of the chip inside the key. The car's computer onboard will recognize that the key is genuine and allow fuel to flow, power the starter or begin it.

Certain key fobs feature pseudo-random code generators, which generate a different unlock code every time you press the button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.

In most cases you can buy an alternative key fob from the dealer or other retailer and have it programmable by a locksmith for your vehicle to fit your specific vehicle.
