These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with computers, and they also have bidirectional interfaces to work with the immobilizer system.

Transponder Chips
Transponder chips are likely to be found in vehicles manufactured within the last 20 years. It's the small piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your car.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by the antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system of the vehicle can then verify that the transponder chip of the key is the correct one for your car.
This is what stops from modifying or hot-wiring the vehicle's ignition system to start it. The chip inside the car key verifies that the owner is the person who owns the vehicle. This will help reduce car theft.
Regular transponder keys are shaped like regular keys and have a plastic top. 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, a 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 the signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer onboard the car detects the signal as correct, it will disable vehicle immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder as being the proper signal, it won't start the engine, and will warn you with flashing lights and an alarm. This is designed to discourage people from trying to hack into the vehicle, however it isn't a foolproof security measure. A skilled and skilled criminal could still evade this system with a specially designed device that blocks the signal.
As programming a car key can see, there are quite a number of benefits to having a transponder key. This is something that all vehicle owners should consider if want to protect their investment and minimize the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making sound chirps to help locate a car in a parking space keys of today can also turn on a heated steering wheel or roll down all of the windows with just a single click. A lot of these additional features may appear convenient however they could make it difficult for you to keep the keys to your car.
Key fobs communicate with each other and the car using radio frequencies which are transmitted through an antenna in the middle of the key. This communication is encrypted to block other key fobs from stealing or modifying the signal.
There are many ways to program a key fob based on your vehicle's make and model. You can sometimes do this yourself, but most newer vehicles require an expert locksmith or dealer to program a replacement or an additional fob.
When you press a key fob's button it transmits an encoded code to the car's radio that it is linked to. The receiver compares the information with the 'allowed signals' stored on the key fob and then it opens or closes the car's doors. If the data doesn't match an chirping sound is heard and the car isn't permitted to operate.
Once the car is paired with a specific fob it will only receive signals from that specific device. Other fobs won't work with the car, even though they look like. This helps to protect the integrity of the car'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 that have original fobs, or genuine replacements offered by the manufacturer. This is because the only place that has the experience to design the replacement fob is the service department of the dealer. However, some fobs from the aftermarket typically for older models with less sophisticated systems can be programmed by consumers without the need for dealers.
