A keyprogrammer is a tool that recodes the transponder chip into the form of a new key fob or mechanical key. It also can clone the data of an existing key to create duplicates. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with computers. They also feature a bidirectional user interface for working with an immobilizer system.

Transponder Chips
Transponder chips can be found in cars that were manufactured in the last 20 years. It's the small piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your car.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is fitted around the barrel that controls your ignition in your vehicle. This allows the computer in your vehicle system to verify that the transponder chip that is in the key is the right one for your particular car.
This is the reason why 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 person who is the owner of the vehicle. This helps to prevent car theft.
Regular transponder keys are designed like regular keys, but with a plastic top. The chip is located inside the plastic part of the keys. There are various cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.
A circuit inside the induction coil will emit a signal when the transponder is placed in the ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer on the car detects this signal as the correct one, it will disable the immobilizer on the vehicle and allow the engine to begin.
If the car doesn't recognize the transponder as being the proper signal, it won't start the engine and will alert you with flashing lights and a siren. This function is designed to discourage people from tampering with the vehicle. However it's not an absolute security measure. A skilled and committed thief could still be able to escape this security system by using a special device to detect the signal.
As you can see there are quite a few advantages to getting a transponder key. All car owners should take this into consideration if they wish to protect their investment and minimize the chance 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 space, today's key fobs can also turn on a heated steering wheel, or roll down all of the windows with a single click . These extra features can make it difficult to locate your car keys.
Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted by an antenna that is located in the center of the key. The transmission is encrypted, which helps to stop others from stealing and replicating the signal.
You can program a keyfob in various ways based on the make and model of your vehicle. Certain cars let you do it yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order to program a new key fob or an additional one.
When you press the button on a key fob, the microchip sends signals to the receiver inside the car with which it is linked. The receiver then compares the data with the 'allowed signals' stored in the key fob and then it opens or closes the car door. If the data doesn't match, a chirping sound is heard and the car isn't permitted to function.
When a car is connected with a specific fob it will only accept signals from that specific device. Other fobs won't work with the car, even if they look like. This safeguards the integrity of the computer system of the vehicle and stops unauthorised key fobs from taking control of it.
Most newer car dealerships will only accept vehicles that have original fobs or genuine replacements offered by the manufacturer. programming car key is due to the fact that preparing a replacement fob requires technological and security skills that is only available in the dealer service department. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems -- can be programmed by the consumer without the need for a dealership.
