Transponder Chips

If your car is made within the last 20 years, it is likely that it has a transponder chip inside of it. It's a small plastic thing on the back of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.

The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is taken up by an antenna attached to the barrel of ignition. This allows the vehicle's computer system to determine if the transponder chip in the key is the correct one for your particular car.

This prevents the vehicle from being started through either hot-wiring or by manipulating. The chip in the key also verifies that you are the legal owner of the vehicle. This helps to prevent car theft.

Transponder keys appear like regular metal keys, but with a plastic cap. The chip is housed in the plastic portion of the key and there are a few different types of cuts on these keys: a regular cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal is received by the chip which sends a signal to the vehicle. If the computer inside the car is able to recognize the signal as correct 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 won't start the engine and alert you with flashing lights and siren. This system is designed to deter individuals from tampering with the vehicle. However, it is not a foolproof measure of security. A determined and skilled thief could still evade this system with a specially designed device that detects the signal.

As you can see, there are quite a few advantages to getting transponder keys. This is something that all vehicle owners should consider if want to safeguard their investment and decrease the risk of theft.

Key Fobs

Key fobs today do more than just lock and unlock doors. They can also start your vehicle from a distance, make chirping sounds to help locate the car or switch on the heated steering wheel. These additional features can make it difficult to find your car keys.

Key fobs communicate with each other and the car using radio frequencies that are transmitted through a small antenna located in the middle of the key. This communication is encrypted, which helps stop others from stealing and retransmitting the signal.

You can program a keyfob in various ways based on the model and make of your car. It is possible to do this yourself, but the majority of newer automobiles require a locksmith shop or a professional to program a replacement or additional fob key programmer.

When you press the button on your key fob, the microchip inside transmits a code to the car's radio that it is linked to. The receiver then compares this information to the signals that are allowed in the fob and then either locks or opens the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't allowed to operate.

Once the car is linked with a specific fob, it will only accept signals from that specific device. As a result, other fobs will not work with the vehicle, even though they appear similar. This safeguards the integrity of the computer system that runs the car and prevents the use of unauthorized key reprogramming fobs to gain control over it.

Most dealerships with newer cars will only deal with vehicles that have original fobs or genuine replacements supplied by the manufacturer. This is because the only place with the expertise to prepare a replacement fob is in the service department of the dealer. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems -- can be programmed by the consumer without the need for a dealership.
