Key Programmers

The key may not function properly or it may not even start the car at all. The reason for this is that the new key has not been programmed into the vehicle's system - and this can be quite expensive. It is recommended to have two keys that are compatible for the modern automobile so that you can program the replacement key when required.

A keyprogrammer is a tool that can recode the transponder chip in a new mechanical or key fob key. It also can clone the data of an existing key to make duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that allows them to communicate with computers. They also feature a bidirectional user interface to work with an immobilizer system.

There are a number of different kinds of keyprogrammers that are available, and they come in a variety of shapes and sizes.

Transponder Chips

If your car was built within the past 20 years, it is likely that it has a transponder inside of it. It's a small plastic thing inside the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.

The chip emits an unintentional radio signal when it is activated by an electromagnetic field. The signal is then received by a specific antenna that is attached to the ignition barrel. This allows the vehicle's computer system to determine if the transponder chip that is in the key is the correct one for the car you have.

This stops the vehicle from starting by hot-wiring or tampering. The chip inside the key also verifies that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.

Transponder keys appear like normal keys but have a plastic cap. The chip is inside the plastic part of the keys. There are various cuts such as a standard cut a Laser cut (also called a sidewinder or Ford Tibbe), and the Ford Tibbe.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal will be taken up by the chip and cause it to send a signal back to the car. If the computer onboard the car detects the signal as being correct it will turn off the car immobilizer, allowing the engine to start.

If the car does not recognize the transponder signal as being the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This feature is designed to discourage people from attempting to alter the vehicle, but it is not a foolproof 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.

As you can see there are quite few advantages to getting a transponder key. This is something that all car owners should consider if they want to safeguard their investment and decrease the chance of theft.

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 roll down all windows with just a single press. A lot of these features may seem convenient however they could make it more difficult to keep the track of 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 in the center of the key. The transmission is encrypted, which helps prevent others from intercepting and retransmitting the signal.

You can program a keyfob in various ways based on the model and brand of your vehicle. You may be able to do it yourself, but the majority of newer vehicles require an expert locksmith or dealer to program a replacement or additional fob.

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

After the car has been paired with a specific fob, it only accepts signals from the device. In turn, other fobs won't be able to work with the vehicle, even though they look the same. This safeguards the integrity of the computer system of the car and blocks unauthorised key fobs from taking control of it.

The majority of newer dealers will only work on a car with original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security knowledge that can only be found in the dealer service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed by consumers without the need for a dealership.
