Transponder Chips
Transponder chips are likely to be found in vehicles manufactured within the last 20 years. This is a little plastic thing on the back of your key which contains a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
When it is activated by an electro-magnetic field, the chip emits a low-frequency signal. The signal is then taken up by an antenna attached to the barrel of ignition. This allows the car's computer system to determine if the transponder chip in the key is the correct one for your particular car.
This is what prevents doing hot-wiring or altering the ignition system of your vehicle to get it started. The chip inside the key also confirms that you are the legal owner of the vehicle. This can reduce car theft.
Transponder keys resemble regular metal keys, but with a plastic cap. The chip is contained inside the plastic portion of the key and there are a few different kinds of cuts available on these keys: a cut laser cut (also known as a sidewinder key) or Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer inside the car recognizes the signal as correct it will turn off the vehicle immobilizer so that the engine can start.
If the car does not recognize the transponder signal as being the correct one, it will stop the engine from running and will notify you by flashing its lights and sounding a siren. This feature is intended to discourage people from attempting to hack into the vehicle, but it isn't a foolproof security measure. A determined and skilled thief can still get around this system using a special device that blocks the signal.

A lot of these additional features may seem convenient but they could make it harder for you to keep track of your car keys.
Key fobs communicate with each other and with the car through radio frequencies which are transmitted through an antenna that is located in the center of the key. This signal is encrypted to stop others from intercepting or replicating the signal.
There are a few different ways to program a key fob based on the vehicle's make and model. Certain models allow you to do this yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order for them program a replacement key fob or additional one.
When you hit the button on a key fob, the microchip inside transmits an informational code to the car key programming and cutting's receiver it is linked to. The receiver then compares the data with the permitted signals stored in the key fob and then locks or opens the car's door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to operate.
Once the car is associated with a particular fob, it can only receive signals from the device. This means that other fobs won't be able to work with the vehicle, even though they look the same. This safeguards the integrity of the computer system of the car and prevents the use of unauthorized key fobs to gain control of it.
The majority of newer dealerships will only deal with vehicles that have original fobs or genuine replacements supplied by the manufacturer. It is because the only place that has the expertise to prepare an appropriate replacement fob is the service department of a dealer. However, some aftermarket fobs typically for older models with less sophisticated systems can be programmed by customers without the need for a dealership.
