A keyprogrammer is a device that recodes the transponder chip in a new key fob or mechanical key. It also can clone information from an existing key in order to create duplicates. These are handheld devices that connect to a programmable car keys's On Board Diagnostics (OBD port). They have diagnostic software that allows them to communicate with computers as well as a bidirectional interface for working with the immobilizer system.

Transponder Chips
Transponder chips are likely to be found in cars that were manufactured within the past 20 years. This is a little plastic thing in the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then amplified by the specific antenna that is fitted around the ignition barrel of your vehicle. The computer system in the vehicle will then confirm that the chip in the key's transponder is the correct one for your car.
This is what prevents hot-wiring or tampering with the ignition system of the vehicle to get it started. The chip inside the key verifies that the owner is the one who owns the vehicle. This can reduce car theft.
Transponder keys that are regular in shape like regular keys, but with an outer layer of plastic. The chip is contained within the plastic portion of these keys. There are a variety of cuts: a standard cut, Laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal will then get absorbed by the chip, causing it to send a signal back to the car. If the computer in the car detects the signal as valid it will turn off the vehicle immobilizer so that the engine can start.
If the car isn't able to recognize the transponder as the correct signal, it won't start the engine, and will alert you with flashing lights and a siren. This is designed to deter people from trying to alter the vehicle, however it's not a 100% security measure. A skilled and skilled criminal could still bypass this system with a specially designed device that intercepts the signal.
As you can see, there are quite a number of benefits to having transponder keys. Every car owner should take this into consideration in order to safeguard their investment and decrease theft risk.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making noises to aid in finding the car in a parking space Key fobs today can also switch on a heated steering wheel or open all windows with just a single press. These extra features could make it difficult to find your car keys.
Key fobs use radio frequencies to connect with one another and with the car. These frequencies are transmitted through a small antenna located inside the middle of the key. This communication is encrypted, which helps to prevent others from intercepting and replicating the signal.
There are many ways to program a key fob based on the vehicle's model and make. You may be able to do it yourself, but most newer vehicles require a dealer or professional locksmith to program a replacement or a second fob.
When you press the button on a key fob the microchip transmits an indication to the receiver in the car with which it is paired. The receiver compares the information with the permitted signals stored in the key fob and then it opens or closes the car's doors. If the data does not match the fob's information, the car won't be allowed to operate.
When a car is connected with a particular fob, it will only accept signals from that device. Other fobs won't work with the car key programmer, despite the fact that they look identical. This protects the integrity of the computer system that runs the car and blocks the use of unauthorized key fobs to gain control of it.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security skills that is only available in the dealer service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems can be programmed by consumers without the need of an authorized dealer.
