Transponder Chips

If your car was manufactured within the past 20 years, chances are it contains a transponder chip within of it. It's the small plastic piece in the head of your car key that contains 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. This signal then gets absorbed by the special antenna that is positioned around the ignition barrel of your vehicle. The computer system of the vehicle will then confirm that the chip in the key's transponder is the right one for your car.

This prevents the vehicle from being started through hot-wiring, or by manipulating. The chip inside the key verifies that the owner is the one who owns the vehicle. This helps to prevent the possibility of theft from your vehicle.

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

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the car's computer recognizes this signal as being the right one, it will shut down the vehicle immobilizer and allow the engine to begin.

If the car does not recognize the transponder signal as being the proper one, it will keep the engine from running and will notify you by flashing its lights and sounding siren. This function is designed to discourage those who would attempt to alter the vehicle. However it's not an unbreakable security measure. A skilled and determined thief could still be able to escape this security system by using a special device to intercept the signal.

You can see that the transponder is a good option. Every car owner should take this into consideration when they want to safeguard their investment and minimize theft risk.

Key Fobs

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

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

Keyfobs can be programmed in various ways based on the make and model of your car. You can sometimes do this yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or an additional fob.

When you hit the button on a key fob it transmits an informational 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 opens or locks the car's doors. If the data does not match the signals, the car will not be allowed to operate.

When a car is connected with a specific fob, it will only accept signals from that device. In turn, other fobs will not work with the vehicle even though they look the same. This is to safeguard the integrity of the car's computer system and to prevent unauthorised key fobs from taking control of the vehicle.

The majority of car dealers who are newer will only work on a car 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 the replacement fob is the service department of a dealer. Certain aftermarket fobs, typically those for older models that have less advanced systems can be programmed with out the need for a dealership.
