Transponder Chips
Transponder chips are likely be found in cars that were manufactured within the last 20 years. It's a tiny plastic thing on the back of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is positioned around the ignition barrel of your vehicle. This allows the vehicle's computer system to verify that the transponder chip inside the key is the right one for the car you have.
This is what prevents hot-wiring or tampering with the vehicle's ignition system to turn it on. The chip inside the key also proves that you are the legitimate owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys look like regular metal keys, but with caps made of plastic. The chip is located inside the plastic portion of these keys. There are a variety of cuts such as a standard cut Laser cut (also known as a sidewinder or Ford Tibbe), and Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the onboard car computer recognizes this signal as the correct one, it will turn off the vehicle immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder as the correct signal, it will not start the engine, and will warn you with flashing lights and siren. This is designed to discourage people from trying to tamper with the vehicle, but it isn't a foolproof security measure. A determined and skilled thief could still evade this system with a specially designed device that detects the signal.
As you can see there are quite number of benefits to having transponder keys. All car owners should consider this if they wish to protect their investment and minimize theft risk.

Key fobs communicate with one other and with the car through radio frequencies that are transmitted by an antenna in the middle of the key. This communication is encrypted to prevent others from stealing or modifying the signal.
There are a few different ways to program a key fob, based on your vehicle's model and make. Certain cars let you do it yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order to program a replacement key fob or additional one.
When you press a key fob's button, the microchip inside transmits a code to the car's radio that it is linked to. The receiver compares this information with the 'allowed' signals on the fob and either locks or opens the door. If the data does not match the signals, the car will not be allowed to drive.
After the car has been associated with a particular fob, it only accepts signals from the device. Other fobs won't work with the car, despite the fact that they appear identical. This protects the integrity of the vehicle's computer system and prevent unauthorised key fobs from taking control of the vehicle.
Most newer car dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security knowledge that is only available in the dealer's service department. Certain aftermarket fobs, typically ones for older models with less advanced systems can be programmed with out the need for a dealer.
