Transponder Chips

Transponder chips can be found in cars that were manufactured within the past 20 years. It's a small piece of plastic inside the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.

The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal is then amplified by the specific antenna that is positioned around the barrel that controls your ignition in your car. This allows the vehicle's computer system to verify that the transponder chip in the key is the right one for your specific vehicle.

This is what stops from modifying or hot-wiring the ignition system of your vehicle to get it started. The chip inside the key verifies that the owner is the one who is the owner of the vehicle. This will help reduce car theft.

Regular transponder keys are shaped like regular keys, but with an outer layer of plastic. The chip is located inside the plastic portion of these keys. There are several different cuts: a standard cut, Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal will be received by the chip, causing it to transmit a signal to the car. If the computer in the car recognizes the signal as valid it will turn off the car immobilizer, allowing the engine to start.

If the car isn't able to recognize the transponder as being the proper signal, it won't start the engine, and will notify you via flashing lights and siren. This is designed to deter people from trying to alter the vehicle, however it isn't a foolproof security measure. A skilled and committed thief could still be able to escape this security system by using a device that can take over the signal.

As you can see there are quite a number of benefits to having a transponder key. Every car owner should consider this if they wish to protect their investment and reduce the risk of theft.

Key Fobs

Key fobs today offer more than locking and unlock doors. They can also turn on the car remotely, emit chirping sounds to help locate cars or turn on the heated steering wheel. These additional features can make it difficult to find your car keys.

Key fobs make use of radio frequencies to communicate with each other and the car. The frequencies are transmitted by a small antenna in the middle of the key. This communication is encrypted, which helps prevent others from intercepting and re-transmitting the signal.

There are several ways to program a key fob, based on the make and model. You may be able to do it yourself, but the majority of newer vehicles require an expert locksmith or dealer to program a replacement or additional fob.

When you press a key fob's button the microchip inside sends an encoded code to the car's receiver that it is paired with. The receiver then compares the data with the permitted signals stored in the key fob and then locks or opens the car's door. If the data does not match the fob's information, the car won't be allowed to run.

After the car has been connected to a specific fob, it will only accept signals from the device. Other fobs will not work with the car, even though they look identical. This protects the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.

Most dealerships with newer cars will only accept cars with original fobs, or genuine replacements supplied by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security knowledge that is only available in the dealer's service department. Some aftermarket fobs, usually ones for older models that have less sophisticated systems, can be programmed without the need for a dealership.
