Transponder Chips

If your car was manufactured within the last 20 years, chances are it has a transponder inside of it. It's a tiny piece of plastic on the back of your key that houses an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.

When it is activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal is then absorbed by a special antenna that is attached to the ignition barrel. This allows the vehicle's computer system to determine if the transponder chip in the key is the correct one for the car you have.

This is the reason why hot-wiring or tampering with the ignition system of the vehicle to get it started. The chip in the car key verifies that the owner is the person who owns the vehicle. This helps to reduce the risk of theft from your car.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer in the car recognizes the signal as being correct it will turn off the vehicle immobilizer to allow the engine start.

If the car doesn't recognize the transponder as being the proper signal, it won't start the engine, and will warn you with flashing lights and an alarm. This system is designed to deter individuals from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and skilled criminal could still bypass this system by using a specific device that intercepts the signal.

It is evident that the transponder is a good option. This is something that all vehicle owners should consider if they want to protect their investment and decrease the chance of theft.

There are many ways to program a key fob depending on the vehicle's make and model. You may be able to do it yourself, however most modern cars require that you visit a dealer or professional locksmith to program a replacement or an additional fob.

When you press a key fob's button it transmits an encoded code to the car's receiver that it is linked to. The receiver compares the information with the permitted signals stored on the key fob and then it opens or closes the car door. If the data does not match the signals, the car will not be allowed to drive.

When a car is connected with a specific fob, it will only receive signals from that device. As a result, other fobs won't be able to work with the vehicle, even though they appear similar. This protects the integrity of the car's computer system and to prevent unauthorised key fobs from taking control of the vehicle.

The majority of newer dealers will only work on a car with original fobs or genuine replacements supplied by the manufacturer. car key programming is because the only place that has the knowledge to create an appropriate replacement fob is the service department of the dealer. However, some fobs from the aftermarket typically for older models with less sophisticated systems can be programmed by the consumer without the need for a dealership.
