Transponder Chips
Transponder chips are likely to be found in cars manufactured within the past 20 years. It's the tiny plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your car.
When activated by an electro-magnetic field, the chip emits a low-level signal. The signal is absorbed by a special antenna attached to the barrel of ignition. This allows the car's computer system to confirm that the transponder chip that is in the key is the correct one for your specific vehicle.
This stops the vehicle from being started by either hot-wiring or by manipulating. The chip inside the key verifies that the owner is the person who owns the vehicle. This helps to prevent car theft.
Transponder keys appear like regular keys made of metal, but with a plastic cap. The chip is located inside the plastic portion of these keys. There are various cuts that are a standard cut, laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.
The circuit in the induction coil will emit a signal when the transponder is placed in the the ignition barrel. The signal will be received by the chip, causing it to send a signal back to the car. If the computer inside the car detects the signal as being correct, it will disable vehicle immobilizer to allow the engine start.
If the car isn't able to recognize the transponder as the correct signal, it won't start the engine, and will notify you via flashing lights and an alarm. This function is designed to discourage individuals from tampering with the vehicle. However, it is not an unbreakable security measure. A skilled and skilled criminal could still bypass this system using a special device that detects the signal.
It is evident that the transponder is an excellent option. All car owners should consider this when they want to safeguard their investment and minimize the chance of theft.

In addition to locking and unlocking doors, launching the car from a distance or making sound chirps to help locate a car in a parking lot Key fobs today can also switch on a heated steering wheel or open all windows with just a single press. A lot of these additional features may seem convenient, but they can also make it harder for you to keep the keys to your car.
Key fobs utilize radio frequencies to connect with one another and with the car. These frequencies are sent via a small antenna that is located inside the middle of the key. The signal is encrypted to stop others from stealing or modifying the signal.
Keyfobs can be programmed 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 automobiles require an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on a key fob, the microchip sends a signal to the receiver inside the vehicle with which it is paired. The receiver then compares this information with the 'allowed' signals stored inside the fob, and either opens or closes the door. If the information isn't in line an chirping sound is heard and the car isn't allowed to operate.
Once the car is associated with a particular fob, it only accepts signals from that device. In turn, other fobs won't work with the vehicle even though they have the same appearance. This safeguards the integrity of the computer system that runs the car and blocks the use of unauthorized key fobs to gain control of it.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security expertise that is only available in the dealer service department. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems -- can be programmed by customers without the need of dealers.
