Transponder Chips
If your car was built within the past 20 years, it is likely that it contains a transponder chip within of it. This is the little plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to your car.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal is then taken up by an antenna attached to the barrel of ignition. This allows the vehicle's computer system to determine if the transponder chip in the key is the right one for your particular car.
This is what stops doing hot-wiring or altering the ignition system of your vehicle to get it started. The chip in the key also confirms that you are the genuine owner of the vehicle. This helps to prevent car theft.
Transponder keys appear like regular keys made of metal but they have a plastic cap. The chip itself is housed within the plastic part of the key and there are a few different kinds of cuts available on the keys: a standard cut laser cut (also called a sidewinder key) or Ford Tibbe key.
A circuit inside the induction coil emits an electrical signal when the transponder is inserted into ignition barrel. The signal will then get received by the chip and cause it to send a signal back to the car. If the computer onboard the car recognizes the signal as correct, it will disable vehicle immobilizer to allow the engine start.
If the car does not recognize the transponder signal as being the right one, it will prevent the engine from running and will notify you by flashing its lights and sounding an alarm. This is designed to discourage people from trying to hack into the vehicle, but it isn't a foolproof security measure. A skilled and determined thief can still get around this system using a special device that intercepts the signal.
As you can see, there are quite a number of advantages to having a transponder key. Every car owner should consider this in order to safeguard their investment and reduce the chance of theft.

These additional features can make it difficult to find your car keys.
Key fobs use radio frequencies to connect with one another and the car. These frequencies are sent by a small antenna within the middle of the key. program car keys is encrypted to stop others from intercepting or replicating the signal.
You can program a keyfob in various ways based on the model and make of your car. You can sometimes do this yourself, but the majority of newer vehicles require a locksmith shop or a professional to program a replacement or additional fob.
When you press the button on a key fob the microchip sends an indication to the receiver in the vehicle that it is paired. The receiver then compares this information with the signals that are allowed inside the fob, and either opens or closes the door. If the information does not match the fob's information, the car won't be allowed to drive.
Once the car is linked with a specific fob, it will only accept signals from that specific device. In turn, other fobs won't be able to work with the vehicle, even though they have the same appearance. This helps to protect the integrity of the car's computer system and to prevent unauthorised key fobs from taking control of the vehicle.
The majority of newer dealerships will only work with vehicles that have original fobs, or genuine replacements offered by the manufacturer. This is because the only place that has the knowledge to create a replacement fob is in the service department of a dealer. However, some aftermarket fobs -- usually those for older models with less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
