These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They come with diagnostic software that enables them to communicate with computers and also provide an interface that works bidirectionally with the immobilizer system.

Transponder Chips
Transponder chips are likely be found in vehicles manufactured within the past 20 years. It's a small plastic thing in the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
When it is activated by an electro-magnetic field the chip emits a low-level signal. The signal is then absorbed by a special antenna that is attached to the ignition barrel. The computer system in the vehicle is then able to verify that the key's transponder chip is the right one for your car.
This is what prevents from modifying or hot-wiring the vehicle's ignition system to start it. The chip in the key also verifies that you are the genuine owner of the vehicle. This can reduce car theft.
Regular transponder keys are shaped like regular keys and have a plastic top. The chip is contained in the plastic portion of the key and there are different kinds of cuts available on the keys: a standard cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.
A circuit within the induction coil emits signals when the transponder is placed in the ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the car's computer recognizes this signal as being the right one, it will turn off the immobilizer on the vehicle and allow the engine to start.
If the vehicle doesn't recognize the transponder as the correct signal, it won't start the engine and notify you via flashing lights and an alarm. This feature is intended to deter people from trying to hack into the vehicle, however it's not a 100% security measure. A skilled and skilled criminal could still bypass this system using a special device that detects the signal.
As you can see, there are quite a number of advantages to having a transponder key. This is something that all vehicle owners should consider if want to safeguard their investment and decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making chirping sounds to help find a car in a parking lot, today's key fobs can also activate a heated steering wheel or open all windows with just a single press. These additional features can make it difficult for you to locate your car keys.
Key fobs are able to communicate with each other and the car using radio frequencies that are transmitted through an antenna that is located in the middle of the key. This communication is encrypted to block other key fobs from intercepting or replicating the signal.
Keyfobs can be programmed in different ways based on the model and make of your car. You may be able to do it yourself, but most newer cars require that you visit a locksmith shop or a professional to program a replacement or additional fob.
When you press the button on a key fob the microchip transmits signals to the receiver inside the vehicle with which it is linked. The receiver then compares the data with the permitted signals stored in the key fob, and then opens or locks the car door. If the information doesn't match the signals, the car will not be allowed to drive.
After the car has been connected to a specific fob, it can only receive signals from the device. In turn, other fobs will not work with the vehicle even if they have the same appearance. This safeguards the integrity of the computer system in the car and prevents unauthorised key fobs from taking control of it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. This is because the only place that has the expertise to prepare a replacement fob is in a dealer's service department. Some aftermarket fobs, usually those from older models with less advanced systems, can be programmed without the need for a dealership.
