Transponder Chips

If your car was manufactured within the past 20 years, chances are it has a transponder chip inside of it. It's the small piece of plastic in 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 an low-level radio signal once it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is attached to the ignition barrel of your car. 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 is what prevents doing hot-wiring or altering the ignition system of the vehicle to get it started. The chip inside the key confirms that the owner is the one who is the owner of the vehicle. This will help reduce car theft.

Transponder keys look like normal keys, but with a plastic cap. The chip is located inside the plastic portion of these keys. There are a variety of cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.

A circuit inside the induction coil emits an electrical signal when the transponder is placed in the an ignition barrel. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer inside the car detects the signal as correct it will turn off the vehicle immobilizer to allow the engine start.

If the car doesn't recognize the transponder as being the proper signal, it will not start the engine, and will notify you via flashing lights and siren. This system is designed to deter individuals from tampering with the vehicle. However it isn't an unbreakable security measure. A skilled and skilled criminal can still get around this system with a specially designed device that blocks the signal.

As you can see there are quite few advantages to getting transponder keys. All car owners must take this into consideration when they want to safeguard their investment and decrease the chance of theft.

Key Fobs

Key fobs today do more than just lock and unlock doors. They can also turn on the car from a distance, make chirping sounds to aid in finding a car, or switch on the heated steering wheel. These extra features can make it difficult for you to find your car keys.

Key fobs communicate with each other and with the car through radio frequencies which are transmitted via a small antenna located in the center of the key. This communication is encrypted to prevent others from intercepting or replicating the signal.

You can program a keyfob in various ways based on the make and model of your vehicle. You may be able to do it yourself, but the majority of newer cars require that you visit an expert locksmith or dealer to program a replacement or a second fob.

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

Once the car is paired with a specific fob it will only accept signals from the device that is associated with it. As a result, other fobs will not work with the vehicle even if they appear similar. This protects the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.

Most dealerships with newer cars will only accept vehicles that have 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 expertise which can only be obtained in the dealer service department. Certain aftermarket fobs, typically ones for older models with less sophisticated systems can be programmed with out the need for a dealership.
