Transponder Chips

Transponder chips can be found in vehicles manufactured within the past 20 years. It's the tiny plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.

The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is then received by a specific antenna that is attached to the ignition barrel. The computer system in the vehicle can then verify that the chip in the key's transponder is the correct one for your vehicle.

This prevents the vehicle from starting by either hot-wiring or by altering the key. The chip in the car key ensures that the owner is the one who is the owner of the vehicle. This will help reduce the possibility of theft from your vehicle.

Regular transponder keys are shaped like regular keys and have an outer layer of plastic. The chip is contained inside the plastic portion of the key, and there are different cuts that can be found on the keys: a cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.

A circuit inside the induction coil emits a signal when the transponder is put into ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer in the car recognizes the signal as correct, it will disable vehicle immobilizer to allow the engine start.

If the car does not recognize the transponder signal as being the correct one, it will prevent the engine from starting and will notify you by flashing its lights and sounding a siren. This is designed to discourage people from trying to tamper with the vehicle, but it's not a 100% security measure. A determined and skilled thief could still bypass this system using a special device that blocks the signal.

Key Fobs

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

Key fobs communicate with one with the car via radio frequencies which are transmitted via an antenna in the center of the key. This communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.

There are a few different ways to program a key fob based on your vehicle's make and model. You can sometimes do this yourself, however most modern automobiles require a dealer or professional locksmith to program a replacement or an additional fob.

When you press the button on a key fob, the microchip transmits signals to the receiver inside the vehicle with which it is paired. The receiver compares the information with the permitted signals stored in the key fob and then it opens or closes the car's doors. If the data does not match the fob's information, the car won't be allowed to run.

After the car has been associated with a particular fob, it will only accept signals from that device. This means that other fobs will not work with the vehicle even though they look the same. This protects the integrity of the computer system in the car and prevents unauthorized key fobs gaining control of it.

The majority of newer dealers will only work on cars with original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place with the knowledge to create the replacement fob is the service department of the dealer. Some fobs from the aftermarket, especially those from older models that have less sophisticated systems, can be programmed without the need for a dealer.
