transponder key programmer Chips
If your car is made in the last 20 years, chances are it has a transponder inside of it. This is a little plastic piece on the back of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by an 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 particular car.
This stops the vehicle from starting by hot-wiring or tampering. The chip inside the key also proves that you are the legal owner of the vehicle. This can help to reduce car theft.
Transponder keys look like normal keys, but with caps made of plastic. The chip is housed in the plastic portion of the key and there are 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.
A circuit within the induction coil will emit a signal when the transponder is put into the ignition barrel. The signal will be absorbed by the chip and cause it to send a signal back to the car. If the computer inside the car is able to recognize the signal as valid it will turn off the car immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine, and will alert you with flashing lights and siren. This system is designed to deter those who would attempt to alter the vehicle. However it's not an unbreakable security measure. A skilled and determined thief could still bypass this system by using a specific device that intercepts the signal.
As you can see there are quite a few advantages to getting a transponder key. This is something that all car owners should consider if are looking to safeguard their investment and decrease the risk of theft.
Key Fobs

A lot of these additional features may appear convenient, but they can also make it difficult for you to keep track of your car keys.
Key fobs use radio frequencies to connect with one another and the car. These frequencies are sent through a small antenna located within the middle of the key. This communication is encrypted, which helps to prevent others from intercepting and replicating the signal.
There are many ways to program a key fob depending on the vehicle's make and model. You can sometimes do this yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or a second fob.
When you hit the button on a key fob it transmits an informational code to the car's receiver that it is linked to. The receiver compared this information to the 'allowed' signals in the fob and then either opens or closes the door. If the data doesn't match, a chirping sound is heard and the car isn't permitted to operate.
Once the car is paired with a particular fob, it will only receive signals from that specific device. As a result, other fobs will not work with the vehicle even if they appear similar. This is to safeguard the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.
Most newer car dealerships will only work with cars with original fobs, or genuine replacements offered by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security skills which can only be obtained in the dealer's service department. Certain aftermarket fobs, typically ones for older models with less advanced systems, can be programmed without the need for a dealer.
