Transponder Chips
If your car was built within the past 20 years, chances are it has a transponder inside of it. It's a small piece of plastic inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is received by a specific antenna that is attached to the ignition barrel. This allows the vehicle's computer system to confirm that the transponder chip in the key is the correct one for your specific vehicle.
This stops the vehicle from being started by either hot-wiring or by altering the key. The chip inside the key also verifies that you are the legal owner of the vehicle. This can reduce car theft.
Transponder keys resemble regular metal keys but have caps made of plastic. The chip itself is housed inside the plastic portion of the key and there are a few different cuts that can be found on these keys: a regular standard cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal is received by the chip which sends a signal to the vehicle. If the onboard car computer detects this signal as the correct one, it will shut down the immobilizer on the vehicle 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 alert you with flashing lights and an alarm. This system is designed to deter those who would attempt to alter the vehicle. However it isn't an absolute security measure. A determined and skilled thief could still evade this system by using a specific device that blocks the signal.
As you can see, there are quite a number of benefits to having transponder keys. This is something that all car owners should consider if they want to safeguard their investment and minimize the chance of theft.
Key Fobs

Key fobs are able to communicate with each with the car via radio frequencies which are transmitted via an antenna in the center of the key. The communication is encrypted, which helps prevent others from intercepting and replicating the signal.
You can program a keyfob in a variety of ways depending on the model and brand of your vehicle. weblink can sometimes do this yourself, but most newer vehicles require an expert locksmith or dealer to program a replacement or an additional fob.
When you hit the button on a key fob it transmits an informational code to the car's radio that it is linked to. The receiver then compares this information with the 'allowed' signals stored inside the fob, and either opens or closes the door. If the information does not match, the car will not be allowed to run.
Once the car is linked with a specific fob, it will only accept signals from that specific device. Other fobs will not work with the car, even if they appear similar. This protects the integrity of the computer system that runs the car and blocks unauthorized key fobs gaining control over it.
Most newer car dealerships will only deal with vehicles that have original fobs, or genuine replacements supplied by the manufacturer. It is because the only place with the experience to design an appropriate replacement fob is the service department of a dealer. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems -- can be programmed by the consumer without the need of a dealership.
