Key Programmers

Modern vehicles typically require a key programming procedure to initialize the vehicle's system and allow the vehicle to start. In a number of cases, the key must be configured by the auto locksmith or dealer. The key may not function correctly or will not start the car at all. This is because the new key has not been programmed to the car's system. This can be quite expensive. This is why it's a great idea to have two keys that work for a modern car and have the replacement key programmed when required.

Keyprogrammers are devices that recodes the transponder chip on an entirely new key fob or mechanical key. It can also clone data from an existing key to make duplicates. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They come with diagnostic software, which allows them to communicate with computers. They also have a bidirectional user interface for working with an immobilizer system.

There are a variety of keyprogrammers on the market. They come in all sizes, shapes, and colors. Certain keyprogrammers are affordable, while others may cost thousands of dollars. Certain are designed for specific automobiles and provide advanced diagnostics of the vehicle's electronic system.

Transponder Chips

If your car was manufactured within the past 20 years, it is likely that it has a transponder inside of it. It's the tiny plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your vehicle.

When it is activated by an electromagnetic field the chip emits a low level signal. The signal is then absorbed by the special antenna that is fitted around the barrel that controls your ignition in your car. The computer system of the vehicle will then confirm that the transponder chip of the key is the correct one for your car.

This stops the vehicle from being started through hot-wiring or manipulating. The chip inside the car key ensures that the owner is the one who owns the vehicle. This helps to reduce the risk of theft from your car.

Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is housed in the plastic portion of the key and there are a few different cuts that can be found on these keys: a regular standard cut, a laser cut (also called a sidewinder) or Ford Tibbe key.

A circuit within the induction coil will emit an electrical signal when the transponder is put into an ignition barrel. The signal will be received by the chip and cause it to transmit a signal to the car. If the computer onboard the car detects the signal as valid, it will disable vehicle immobilizer, allowing the engine to start.

If the vehicle does not recognize the transponder signal as the proper one, it will stop the engine from running and will alert you by flashing its lights and sounding a siren. This system is designed to deter people from tampering with the vehicle. However it isn't an absolute security measure. A skilled and committed thief could still be able to get around this system using a device that can detect the signal.

As you can see there are quite number of benefits to having a transponder key. This is something that all vehicle owners should consider if they are looking to safeguard their investment and minimize the chance of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car from a distance or making noises to aid in finding the car in a parking lot, today's key fobs can also turn on a heated steering wheel, or roll down all windows with a single button press. Many of these extra features may appear convenient however they could make it more difficult to keep track of your car keys.

Key fobs communicate with each with the car via radio frequencies that are transmitted by a small antenna located in the center of the key. This signal is encrypted to prevent others from stealing or stealing the signal.

Keyfobs can be programmed in various ways based on the model and brand of your vehicle. You may be able to do it yourself, but most newer cars require that you visit an expert locksmith or dealer to program a replacement or an additional fob.

When you hit the button on a key fob, the microchip inside transmits a code to the mobile car key programmer's receiver that it is paired with. The receiver compares the information with the 'allowed signals' that are stored in the key fob, and then it opens or closes the car door. If the data does not match, the car will not be allowed to drive.

Once the car has been associated with a particular fob, it can only receive signals from the device. Other fobs will not work with the car, even though they look identical. This helps to protect the integrity of the vehicle's computer system, and also to stop unauthorized key fobs from gaining control over the vehicle.

Most newer car dealers will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is because the only place that has the knowledge to create a replacement fob is in the service department of the dealer. Some aftermarket fobs, usually those from older models that have less advanced systems can be programmed without the need for a dealer.
