Transponder Chips

If your car was built in the last 20 years, it is likely that it has a transponder chip inside of it. This is a little piece of plastic inside the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.

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

This prevents 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 appear like normal keys, but with caps made of plastic. The chip is inside the plastic part of the keys. There are several different cuts that are a standard cut, laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.

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

If the car does not recognize the transponder signal as being the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding an alarm. This feature is designed to discourage individuals from tampering with the vehicle. However it's not an unbreakable security measure. A skilled and determined thief can still get around this system using a special device that detects the signal.

As you can see, there are quite a number of advantages to having a transponder key. All car owners must take this into consideration in order to safeguard their investment and reduce theft risk.

Key Fobs

Key fobs today can offer more than locking and unlock doors. They can also start the vehicle remotely, emit chirping sounds to aid in finding the car or turn on the heated steering wheel. A lot of these features may seem convenient however they could make it difficult for you to keep track of your car keys programmed.

Key fobs utilize radio frequencies to connect with one another and the car. These frequencies are transmitted through a small antenna located within the middle of the key. The communication is encrypted, which helps to stop others from stealing and retransmitting the signal.

There are many ways to program a key fob, based on the model and make. You can sometimes do this yourself, however most modern cars require that you visit a locksmith shop or a professional to program a replacement or an additional fob.

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

Once the car is associated with a particular fob, it can only receive signals from that device. This means that other fobs won't be able to work with the vehicle even if they have the same appearance. This is to safeguard the integrity of the car's computer system and prevent unauthorized key fobs from gaining control of the vehicle.

The majority of newer dealers will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security expertise that is only available in the dealer's service department. However, some aftermarket fobs typically for older models that have less sophisticated systems -- can be programmed by customers without the need for a dealership.
