These are handheld devices connected to a car's On Board Diagnostics (OBD port).

Transponder Chips
If your car was manufactured in the past 20 years, chances are it has a transponder chip inside of it. It's the small plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is taken up by an antenna attached to the ignition barrel. The computer system in the vehicle is then able to verify that the chip in the key's transponder is the right one for your car.
This stops the vehicle from being started through hot-wiring or manipulating. The chip inside the key also verifies that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys that are regular in shape like regular metal keys with a plastic top. The chip is located inside the plastic part of these keys. There are various cuts such as a standard cut laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.
A circuit within the induction coil will emit signals when the transponder is inserted into the ignition barrel. The signal will then get taken up by the chip, causing it to transmit a signal back to the car. If the onboard car computer detects this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder signal as the correct one, it will stop the engine from starting and will alert you by flashing its lights and sounding an alarm. This feature is designed to discourage people from attempting to alter the vehicle, but it isn't a foolproof security measure. A skilled and determined thief could still evade this system using a special device that blocks the signal.
You can see that the transponder is an excellent option. This is something that all vehicle owners should consider if they want to protect their investment and decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making noises to aid in finding a car in a parking lot Key fobs today can also switch on the heated steering wheel or open all windows with a single press. Many of these extra features may appear convenient, but they can also make it more difficult to keep the keys to your car.
Key fobs utilize radio frequencies to communicate with one another and with the car. The frequencies are transmitted via a small antenna that is located in the middle of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal.
Keyfobs can be programmed in various ways based on the model and make of your vehicle. It is possible to do this yourself, however most modern vehicles require a dealer or professional locksmith to program a replacement or an additional fob.
When you press the button on a key fob the microchip transmits a signal to the receiver inside the car with which it is linked. The receiver then compares this information with the 'allowed' signals stored in the fob and then either locks or opens the door. If the data does not match, the car will not be allowed to run.
Once the car has been connected to a specific fob, it can only receive signals from the device. Other fobs will not work with the car, even if they look like. This protects 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 deal with vehicles that have 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 expertise which can only be obtained in the dealer's service department. Some aftermarket fobs, usually ones for older models that have less advanced systems can be programmed without the need for a dealership.
