Key Programmers

Modern automobiles often require a key programming a key process to start the system of the vehicle and allow the vehicle to begin. In some cases the key will have to be programmed by an auto locksmith or dealer. This is because the key could not function correctly, or it will not start the car at all. The reason is because the new key has not been programmed into the vehicle's system - and this can be quite costly. It's best to have two keys that are compatible for the modern automobile so that you can program the replacement key if required.

A keyprogrammer can reprogram a transponder chip on the new mechanical key or key fob. It is also able to copy the data of an existing key, allowing duplicates to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that allows them to communicate with computers and also provide bidirectional interfaces to work with the immobilizer system.

There are a variety of keyprogrammers available on the market. They come in all sizes, shapes, and colors. Certain keyprogrammers are affordable while others may cost thousands of dollars.

Transponder Chips

Transponder chips can be found in cars manufactured within the past 20 years. It's a tiny plastic thing in the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.

The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is then taken up by an antenna attached to the ignition barrel. The computer system of the vehicle can then verify that the chip in the key's transponder is the correct one for your vehicle.

This is what stops hot-wiring or tampering with the ignition system of the vehicle to turn it on. The chip in the key also verifies that you are the legitimate owner of the vehicle. This will help reduce car theft.

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

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer on the car recognizes this signal as the correct one, it will turn off the immobilizer on the vehicle and allow the engine to start.

If the vehicle doesn't recognize the transponder signal as being the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding an alarm. This feature is designed to discourage those who would attempt to alter the vehicle. However, it is not a foolproof measure of security. A skilled and determined thief could still be able to escape this security system by using a special device to intercept the signal.

It is evident that the transponder is a good option. This is something that all car owners should consider if they want to protect their investment and reduce the chance of theft.

Key Fobs

Key fobs today do more than just lock and unlock doors. They can also turn on the car remotely, emit chirping sounds to help locate a car, or turn on the heated steering wheel. These additional features can make it difficult to find your car keys.

Key fobs use radio frequencies to communicate with each other and the car. These frequencies are transmitted via a small antenna that is located within the middle of the key. This signal is encrypted to block other key fobs from stealing or modifying the signal.

There are a few different ways to program a key fob based on the model and make. You can sometimes do this yourself, however most modern automobiles 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 signals to the receiver in the vehicle with which it is paired. The receiver compared the information with the permitted signals stored in the key fob and then locks or opens the car door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't able to function.

Once the car is linked with a specific fob, it will only accept signals from the device that is associated with it. Other fobs won't work with the car, even though they appear like. This protects the integrity of the computer system in the car and blocks unauthorized key fobs gaining control over it.

The majority of newer dealers will only work on a car with original fobs or genuine replacements offered by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security expertise which can only be obtained in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems can be programmed by customers without the need for an authorized dealer.
