If your car was built in the past 20 years, it is likely that it contains a transponder chip within of it. This is the little plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your vehicle.

When it is activated by an electromagnetic field the chip emits a low level signal. The signal is then absorbed by a special antenna that is attached to the ignition barrel. The computer system in the vehicle is then able to verify that the key’s transponder chip is the correct one for your car.

This prevents the vehicle from being started by hot-wiring, or by altering the key. The chip inside the key verifies that the owner is the one who owns the vehicle. This will help reduce car theft.

Transponder keys look like normal keys but they have a plastic cap. The chip itself is housed within the plastic part of the key and there are different kinds of cuts available on these keys: a regular standard cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer on the car detects this signal as the correct one, it will shut down the immobilizer on the vehicle and allow the engine to begin.

If the vehicle doesn’t recognize the transponder as being the proper signal, it will not start the engine and will warn you with flashing lights and an alarm. This feature is designed to discourage individuals from tampering with the vehicle. However it isn’t a foolproof measure of security. A determined and skilled thief could still evade this system by using a specific device that detects the signal.

You can see that a transponder is a great option. Every car owner should take this into consideration if they wish to protect their investment and reduce theft risk.

Key Fobs

Key fobs today offer more than locking and unlock doors. They can also start your vehicle remotely, emit chirping sounds to help locate the car or switch on the heated steering wheel. A lot of these features might seem useful but they could make it harder for you to keep the keys to your car.

Key fobs communicate with one other and with the car through radio frequencies that are transmitted through a small antenna located in the middle of the key. The transmission is encrypted, which helps stop others from stealing and re-transmitting the signal.

There are several ways to program a key fob based on your vehicle’s make and model. It is possible to do this yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or an additional fob.

When you press the button on a key fob, the microchip transmits an indication to the receiver inside the vehicle that it is paired. The receiver compared this information with the ‘allowed’ signals on the fob and either locks or opens the door. If the data doesn’t match an chirping sound is heard and the car isn’t allowed to operate.

After the car has been paired with a specific fob, it can only receive signals from that device. Other fobs won’t work with the car, even though they look like. This ensures the security of the computer system of the car and prevents unauthorized key fobs gaining control of it.

Most dealerships with newer cars will only deal with cars with original fobs, or genuine replacements supplied by the manufacturer. This is because the only place that has the knowledge to create a replacement fob is in a dealer’s service department. However, some aftermarket fobs typically for older models with less sophisticated systems — can be programmed by consumers without the need of an authorized dealer.
