Transponder Chips
Transponder chips can be found in vehicles manufactured in the last 20 years. This is a little plastic piece on the back of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
When it is activated by an electromagnetic field, the chip emits a low-level signal. The signal is taken up by an antenna attached to the ignition barrel. This allows the computer in your vehicle system to confirm that the transponder chip in the key is the right one for your particular car.
This stops the vehicle from being started through either hot-wiring or by altering the key. The chip in the key also verifies that you are the legitimate owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.

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 computer onboard the car is able to recognize the signal as valid it will turn off the car immobilizer so that the engine can start.
If programming key fob near me isn't able to recognize the transponder as being the proper signal, it won't start the engine and will notify you via flashing lights and siren. This is designed to discourage people from trying to tamper with the vehicle, however it isn't a foolproof security measure. A skilled and committed thief could still be able to escape this security system by employing a device designed to take over the signal.

Key fobs make use of radio frequencies to connect with one another and the car. The frequencies are transmitted via a small antenna that is located in the middle of the key. This communication is encrypted, which helps keep others from stealing and replicating the signal.
You can program a keyfob in a variety of ways depending on the model and make of your vehicle. Certain models allow you to do this yourself. However, the majority of newer models require you to visit an expert locksmith or dealer for them program a replacement key fob or additional one.

The receiver compared this information to the signals that are allowed in the fob and then either opens or locks the door. If the data does not match the fob's information, the car won't be allowed to drive.
Once the car has been paired with a specific fob, it only accepts signals from that device. Other fobs will not work with the car, even if they look identical. This is to safeguard the integrity of the vehicle's computer system and prevent unauthorised key fobs from taking control over the vehicle.
Most newer car dealerships will only accept cars that have original fobs or genuine replacements offered by the manufacturer.
