Transponder Chips
If your car was manufactured in the past 20 years, it is likely that it has a transponder inside of it. This is a little piece of plastic on the back of your key which contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
When activated by an electro-magnetic field the chip emits a low level signal. The signal is then amplified by the specific antenna that is attached to the ignition barrel of your car. This allows the car's computer system to confirm that the transponder chip in the key is the right one for the car you have.
This stops the vehicle from being started through hot-wiring, or by altering the key. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are shaped like regular metal keys with a plastic top. The chip is contained within the plastic portion of these keys. There are various cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.
A circuit within the induction coil emits signals when the transponder is placed in the the ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer inside the car detects the signal as valid it will turn off the car immobilizer to allow the engine start.
If the vehicle does not recognize the transponder signal as the right one, it will prevent the engine from starting and will notify you by flashing its lights and sounding an alarm. This function is designed to discourage individuals from tampering with the vehicle. However it's not an absolute security measure. A skilled and determined thief could still evade this system with a specially designed device that intercepts the signal.
As you can see there are quite a number of advantages to having a transponder key. This is something that all car owners should consider if want to safeguard their investment and decrease the risk of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start the car remotely, make chirping noises to aid in finding cars or switch on the heated steering wheel. These additional features can make it difficult to locate your car keys.
Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are transmitted by a small antenna 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 make and model. You can sometimes do this yourself, but most newer vehicles require an expert locksmith or dealer to program a replacement or an additional fob.
When you press a key fob's button, the microchip inside transmits a code to the car's receiver it is paired with. The receiver compared the information with the permitted signals stored on the key fob and then it opens or closes the car's door. If the data does not match, the car will not be allowed to run.
Once the car is linked with a particular fob, it will only accept signals from that specific device. Other fobs will not work with the car, even if they look like. This is to safeguard the integrity of the car's computer system, and also to stop unauthorised key fobs from taking control of the vehicle.
The majority of newer dealers will only work on a car with original fobs or genuine replacements supplied by the manufacturer. The reason for this is that the only place that has the experience to design the replacement fob is a dealer's service department. Some fobs from the aftermarket, especially those from older models that have less sophisticated systems can be programmed with out the need for a dealership.
