Transponder Chips
If your car was built within the past 20 years, it is likely that it has a transponder inside of it. It's the small 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 taken up by an antenna attached to the barrel of ignition. This allows the car's computer system to verify that the transponder chip inside the key is the right one for your specific vehicle.
This prevents the vehicle from being started through hot-wiring, or by tampering. automotive key programming near me in the car key verifies that the owner is the person who owns the vehicle. This can help to reduce car theft.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. 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 a valid signal, it won't start the engine, and will warn you with flashing lights and siren.

The receiver compared the information with the 'allowed signals' stored in the key fob, and then it opens or closes the car's doors. If the information doesn't match, a chirping sound is heard and the car isn't permitted to function.
Once the car is linked with a specific fob it will only receive signals from that specific device. Other fobs won't work with the car, even though they appear similar. This is to safeguard the integrity of the car's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.

However, some aftermarket fobs that are typically designed for older models with less sophisticated systems -- can be programmed by customers without the need of dealers.
