Transponder Chips

If your car was built in the last 20 years, then it contains a transponder chip within of it. It's the tiny piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.

The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then absorbed by a special antenna attached to the ignition barrel. This allows the vehicle's computer system to determine if the transponder chip inside the key is the right one for your particular car.

This is what stops from modifying or hot-wiring the ignition system of your vehicle to turn it on. The chip inside the key also proves that you are the legitimate owner of the vehicle. This will help reduce car theft.

Transponder keys appear like normal keys, but with caps made of plastic. The chip is housed inside the plastic portion of the key, and there are a few different kinds of cuts available on these keys: a standard cut laser cut (also called a sidewinder) or Ford Tibbe key.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer in the car is able to recognize the signal as valid, it will disable vehicle immobilizer, allowing the engine to start.

If the car does not recognize the transponder signal as being the right one, it will prevent the engine from starting and will notify you by flashing its lights and sounding a siren. This system is designed to deter people from tampering with the vehicle. However it isn't a foolproof measure of security. A skilled and determined thief can still get around this system with a specially designed device that intercepts the signal.

You can see that a transponder is a great option. All car owners should consider this when they want to safeguard their investment and reduce the risk of theft.

Key Fobs

Key fobs today can be more than just a way to lock and unlock doors. They can also start your vehicle remotely, make chirping noises to help locate a car or turn on the heated steering wheel. A lot of these features might seem useful but they could make it harder for you to keep the keys to your car.

Key fobs utilize radio frequencies to connect with one another and with the car. These frequencies are transmitted through a small antenna located in the middle of the key. This communication is encrypted to prevent others from stealing or modifying the signal.

There are many ways to program a key fob based on the vehicle's model and make. Certain cars let you do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a new key fob or additional one.

When you press the button on a key fob the microchip transmits signals to the receiver in the car that it is paired. The receiver compares this information to the signals that are allowed on the fob and either opens or locks the door. If the information does not match the fob's information, the car won't be allowed to operate.

After the car has been associated with a particular fob, it only accepts signals from the device. Other fobs won't work with the car, despite the fact that they look identical. This safeguards the integrity of the computer system in the car and prevents the use of unauthorized key fobs to gain control over it.

Most dealerships with newer cars will only deal with cars with original fobs or genuine replacements sold by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security skills that is only available in the dealer's service department. However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by the consumer without the need for dealers.
