Transponder Chips

If your car was built in the past 20 years, chances are it has a transponder 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 an individual code for the specific vehicle you own.

When it is activated by an electromagnetic field the chip emits a low level signal. The signal is then taken up by an antenna that is attached to the ignition barrel. The computer system of the vehicle is then able to verify that the transponder chip of the key is the right one for your car.

This is what stops doing hot-wiring or altering the ignition system of your vehicle to start it. The chip inside the key ensures that the owner is the person who owns the vehicle. This can reduce car theft.

Transponder keys appear like normal keys, but with a plastic cap. The chip is located inside the plastic part of the keys. There are several different cuts: a standard cut, laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.

A circuit inside the induction coil will emit an electrical signal when the transponder is inserted into the ignition barrel. The signal will then get received by the chip, causing it to send a signal back to the car. If the computer in the car detects the signal as being correct it will turn off the vehicle immobilizer so that the engine can start.

If the car doesn't recognize the transponder as a valid signal, it will not start the engine and notify you via flashing lights and an alarm. This is designed to discourage people from trying to alter the vehicle, but it's not a 100% security measure. A determined and skilled thief could still bypass this system with a specially designed device that intercepts the signal.

As you can see there are quite a number of benefits to having transponder keys. This is something that all car owners should think about if they want to safeguard their investment and reduce the chance of theft.

Key Fobs

Key fobs today offer more than locking and unlock doors. They can also turn on the car remotely, make chirping noises to aid in finding cars, or switch on the heated steering wheel. These extra features can make it difficult for you to locate your car keys.

Key fobs communicate with each other and with the car through radio frequencies which are transmitted via an antenna that is located in the middle of the key. This communication is encrypted, which helps stop others from stealing and retransmitting the signal.

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

When you press a key fob's button the microchip inside sends an informational code to the car's receiver that it is linked to. The receiver compares this information to the 'allowed' signals on the fob and either locks or opens the door. If the information does not match, the car will not be allowed to drive.

Once the car has been connected to a specific fob, it only accepts signals from the device. Other fobs won't work with the car, even though they appear identical. This protects the integrity of the car's computer system and prevent unauthorized key fobs from gaining control of the vehicle.

Most dealerships with newer cars will only accept cars with original fobs, or genuine replacements sold by the manufacturer. This is because the only place with the experience to design a replacement fob is in the service department of the dealer. Some fobs from the aftermarket, especially those from older models that have less advanced systems can be programmed with out the need for a dealership.
