Transponder Chips

Transponder chips are likely be found in vehicles manufactured in the last 20 years. It's the tiny piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your vehicle.

When it is activated by an electro-magnetic field the chip emits a low-level signal. The signal is then received by a specific antenna that is attached to the ignition barrel. This allows the car's computer system to verify that the transponder chip that is in the key is the right one for your specific vehicle.

This stops the vehicle from being started by hot-wiring, or by tampering. The chip inside the key also verifies that you are the legal owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

Transponder keys resemble regular keys programmed made of metal but have a plastic cap. The chip is housed inside the plastic portion of the key and there are a few different cuts that can be found on the keys: a standard cut laser cut (also called a sidewinder key), or a Ford Tibbe key.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer inside the car is able to recognize the signal as valid it will turn off the vehicle immobilizer to allow the engine start.

If the vehicle doesn't recognize the transponder as the correct signal, it will not start the engine, and will notify you via flashing lights and an alarm. This feature is designed to discourage people from trying to alter the vehicle, but it is not a foolproof security measure. A skilled and skilled criminal can still get around this system with a specially designed device that detects the signal.

Many of these extra features might seem useful, but they can also make it harder for you to keep track of your car key reprogrammed keys.

Key fobs are able to communicate with each other and the car using radio frequencies that are transmitted by an antenna that is located in the center of the key. The transmission is encrypted, which helps keep 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, however most modern automobiles require an expert locksmith or dealer to program a replacement or a second fob.

When you press the button on a key fob the microchip transmits an indication to the receiver inside the vehicle with which it is linked. The receiver then compares this information to the 'allowed' signals inside the fob, and either opens or locks the door. If the data does not match, the car will not be allowed to drive.

Once the car is connected to a specific fob, it can only receive signals from the device. Other fobs won't work with the car key programmers, despite the fact that they look like. This helps to protect the integrity of the car's computer system and prevent unauthorized key fobs from gaining control of the vehicle.

Most dealerships with newer cars will only work with cars with original fobs, or genuine replacements supplied by the manufacturer. This is because preparing a replacement fob requires technological and security expertise that is only available in the dealer service department. Some aftermarket fobs, usually ones for older models with less sophisticated systems can be programmed car keys with out the need for a dealership.
