Key Programmers

This is because the key may not function properly or start the car at all. The reason for this is that the new key hasn't been programmed to the car's system. This can be very costly. This is why it's a great idea to have two keys that work for a modern automobile and to have the replacement key programmed when necessary.

A keyprogrammer is a device which can reprogram the transponder chip in a new mechanical or key fob key. It can also clone information from an existing key in order to create duplicates. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They have diagnostic software that enables them to communicate with computers, and they also have an interface that works bidirectionally with the immobilizer system.

There are a number of different kinds of keyprogrammers on the market, and they come in a variety of shapes and sizes.

Transponder Chips

If your car is made in the past 20 years, then it has a transponder chip inside of it. It's a tiny plastic thing inside the head of your mobile key programmer that contains a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.

The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is absorbed by a special antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to verify that the transponder chip in the key is the right one for the car you have.

This stops the vehicle from being started by hot-wiring, or by altering the key. The chip in the car key confirms that the owner is the person who owns the vehicle. This can reduce car theft.

Transponder keys look like regular keys made of metal but they have a plastic cap. The chip itself is housed inside the plastic portion of the key and there are a few different types of cuts on these keys: a standard cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.

A circuit inside the induction coil will emit signals when the transponder is inserted into ignition barrel. The signal will then get received by the chip, causing it to transmit a signal to the car. If the computer inside the car recognizes the signal as correct it will turn off the car immobilizer to allow the engine start.

If the car doesn't recognize the transponder as a valid signal, it will not start the engine and warn you with flashing lights and a siren. This feature is designed to discourage people from attempting to alter the vehicle, however it's not a 100% security measure. A skilled and determined thief may still be able to escape this security system by using a special device to detect the signal.

You can see that the transponder is a good option. Every car owner should take this into consideration in order to safeguard their investment and minimize the risk of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car remotely, or making chirping sounds to help find the car in a parking lot, today's key fobs can also switch on a heated steering wheel, or open all windows with a single button push. These additional features can make it difficult to find your car keys.

Key fobs make use of radio frequencies to communicate with one another and with the car. These frequencies are transmitted through a small antenna located in the middle of the key. The communication is encrypted, which helps to stop others from stealing and replicating the signal.

Keyfobs can be programmed in a variety of ways depending on the model and brand of your vehicle. Some cars allow you to do this by yourself. However, most newer models require you to visit a professional locksmith or dealer to program a replacement key fob, or an alternative one.

When you press the button on a key fob, the microchip sends a signal to the receiver in the vehicle that it is paired. The receiver compared the information with the permitted signals stored in the key fob and then locks or opens the car's door. If the data does not match the fob's information, the car won't be allowed to run.

Once the car is paired with a particular fob, it will only accept signals from that specific device. This means that other fobs won't be able to work with the vehicle, even though they have the same appearance. This is to safeguard the integrity of the car's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.

The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security knowledge that can only be found in the dealer service department. However, some aftermarket fobs typically for older models with less sophisticated systems can be programmed by customers without the need for dealers.
