Transponder Chips
If your car is made in the past 20 years, then it has a transponder chip inside of it. This is a little plastic piece on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
When it is activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal is then absorbed by the special antenna that is fitted around the ignition barrel of your vehicle. The computer system in the vehicle can then verify that the transponder chip of the key is the correct one for your car.
This stops the vehicle from being started through either hot-wiring or by altering the key. The chip inside the car key verifies that the owner is the one who is the owner of the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular keys, but with an outer layer of plastic. The chip itself is housed within the plastic part of the key and there are a few different cuts that can be found on these keys: a cut laser cut (also called a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal will be absorbed by the chip and cause it to transmit a signal back to the car. If the computer inside the car is able to recognize the signal as being correct it will turn off the vehicle immobilizer, allowing the engine to start.
If the vehicle does not recognize the transponder signal as being the right one, it will prevent the engine from starting and will alert you by flashing its lights and sounding a siren. This system is designed to deter people from tampering with the vehicle. However it isn't an absolute security measure. A skilled and committed thief might be able bypass this system by employing a device designed to intercept the signal.

These extra features can make it difficult to find your car keys.
Key fobs communicate with one other and with the car through radio frequencies which are transmitted by an antenna in the center of the key. The transmission is encrypted, which helps to stop others from stealing and re-transmitting the signal.
You can program a keyfob in various ways based on the model and brand of your vehicle. Certain cars let you do this yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order to program a replacement key fob or an additional one.
When you press the button on a key fob, the microchip sends signals to the receiver in the car that it is paired. The receiver then compares the data with the 'allowed signals' stored on the key fob and then locks or opens the car's door. If the information does not match the fob's information, the car won't be allowed to operate.
After the car has been paired with a specific fob, it can only receive signals from that device. Other fobs won't work with the car, even if they look identical. This protects the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control over the vehicle.
The majority of newer dealerships will only accept cars that have original fobs, or genuine replacements sold by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security knowledge which can only be obtained in the dealer's service department. Some fobs from the aftermarket, especially those for older models with less sophisticated systems can be programmed with out the need for a dealership.
