Transponder Chips
If your car is made in the past 20 years, then it has a transponder inside of it. This is the little plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your car.
When activated by an electro-magnetic field the chip emits a low-frequency signal. The signal is absorbed by a special antenna that is attached to the ignition barrel. The computer system in the vehicle can then verify that the key's transponder chip is the correct one for your vehicle.
This prevents the vehicle from being started through hot-wiring or tampering. The chip in the key also verifies that you are the genuine owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Regular transponder keys are shaped like regular metal keys with an outer layer of plastic. The chip is contained within the plastic part of these keys. There are a variety of cuts: a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe) and the Ford Tibbe.
A circuit within the induction coil will emit a signal when the transponder is inserted into ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer onboard the car recognizes the signal as correct it will turn off the car immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and notify you via flashing lights and a siren. This feature is designed to discourage individuals from tampering with the vehicle. However, it is not an absolute security measure. A skilled and skilled criminal can still get around this system with a specially designed device that blocks the signal.
You can see that the transponder is an excellent option. This is something that all car owners should consider if are looking to safeguard their investment and reduce the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making chirping sounds to help find a car in a parking lot Key fobs today can also switch on a heated steering wheel, or roll down all windows with a single button click. A lot of these additional features may seem convenient but they could make it more difficult to keep track of your car keys.
Key fobs communicate with one other and with the car through radio frequencies which are transmitted through an antenna in the center of the key. The transmission is encrypted, which helps stop others from stealing and replicating the signal.
Keyfobs can be programmed in various ways based on the make and model of your car. It is possible to do this yourself, but the majority of newer automobiles require an expert locksmith or dealer to program a replacement or an additional fob.
When you press the button on your key fob the microchip inside sends an encoded code to the car's receiver it is paired with. The receiver compared the information with the 'allowed signals' stored in the key fob, and then it opens or closes the car door. If the information doesn't match an chirping sound is heard and the car isn't permitted to operate.
Once the car is associated with a particular fob, it only accepts signals from that device. In turn, other fobs will not work with the vehicle even though they look the same. This protects the integrity of the computer system of the car and blocks the use of unauthorized key fobs to gain control over it.
Most dealerships with newer cars will only work with vehicles that have original fobs, or genuine replacements supplied by the manufacturer. This is because preparing a replacement fob requires technological and security skills that can only be found in the dealer service department. Some aftermarket fobs, usually those from older models that have less sophisticated systems, can be programmed without the need for a dealer.
