Transponder Chips

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

When it is activated by an electro-magnetic field the chip emits a low-frequency signal. The signal is then absorbed by a special antenna attached to the ignition barrel. This allows the computer in your vehicle system to verify that the transponder chip inside the key is the right one for the car you have.

This prevents the vehicle from starting by hot-wiring or tampering. The chip in the car key verifies that the owner is the person who is the owner of the vehicle. This will help reduce car theft.

Regular transponder keys are shaped like regular keys and have an outer layer of plastic. The chip is contained within the plastic portion of the keys. There are a variety of cuts that are a standard cut, a Laser cut (also known as a sidewinder or Ford Tibbe) and the Ford Tibbe.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the computer in the car detects the signal as being correct it will turn off the car immobilizer so that the engine can start.


If the car isn't able to recognize the transponder as being the proper signal, it will not start the engine, and will alert you with flashing lights and a siren. This feature is intended to deter people from trying to tamper with 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 intercepts the signal.

As you can see there are quite a number of advantages to having a transponder key. This is something that all vehicle owners should consider if are looking to safeguard their investment and reduce the chance of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car remotely or making sound chirps to help locate the car in a parking space, today's key fobs can also turn on a heated steering wheel or open all windows with a single push. Many of these extra features might seem useful but they could make it harder for you to keep track of your car keys.

Key fobs communicate with each other and the car using radio frequencies which are transmitted through a small antenna located in the center of the key. The transmission is encrypted, which helps keep others from stealing and retransmitting the signal.

You can program a keyfob in a variety of ways depending on the model and make of your car. You may be able to do it 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 signals to the receiver in the car with which it is linked. The receiver compares this information to the 'allowed' signals stored in the fob and then either locks or opens the door. If the information doesn't match the signals, the car will not be allowed to operate.

Once the car is paired with a specific fob, it will only accept signals from the device that is associated with it. Other fobs will not work with the car, even if they look similar. This protects the integrity of the computer system that runs the vehicle and stops the use of unauthorized key fobs to gain control over it.

Most newer car dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. The reason for this is that the only place with the experience to design an appropriate replacement fob is the service department of a dealer. However, some aftermarket fobs typically for older models that have less sophisticated systems -- can be programmed by customers without the need of an authorized dealer.
