Key Programmers

Modern vehicles typically require a key programming process to set up the car's system and allow the car to start. In certain instances the key will have to be programmed by an auto locksmith or dealer. This is because the key might not function properly, 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 expensive. This is why it's a good idea to have two working keys for a modern automobile and to have the replacement key programmed when needed.

A keyprogrammer is a device that recodes the transponder chip on the form of a new key fob or mechanical key. It is also able to copy the information from an existing key which allows duplicate keys to be made. 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 the computer and also provide a bidirectional interface for working with the immobilizer system.

There are many various kinds of keyprogrammers on the market and they are available in a variety of shapes and sizes.

They are less expensive than visiting a dealership, but still not cheap. Before buying one do some research on the seller. Some aren't reliable and could damage your vehicle.

Transponder Chips

If your car was manufactured within the past 20 years, then it has a transponder chip inside of it. This is a little plastic thing on the back of your key that contains an RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.

The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then absorbed by a special antenna that is attached to the barrel of ignition. The computer system of the vehicle can then verify that the transponder chip of the key is the right one for your vehicle.

This stops the vehicle from being started through hot-wiring, or by altering the mobile key programming. The chip inside the key also verifies that you are the genuine owner of the vehicle. This can reduce car theft.

Transponder keys that are regular in shape like regular keys and have a plastic top. The chip is contained within the plastic part of these keys. There are various cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal will be taken up by the chip and cause it to transmit a signal back to the car. If the car's computer recognizes this signal as being the right one, it will disable the immobilizer on the vehicle and allow the engine to start.

If the vehicle doesn't recognize the transponder as the correct signal, it won't start the engine, and will alert you with flashing lights and siren. This feature is designed to discourage people from trying to tamper with the vehicle, however it isn't a foolproof security measure. A determined and skilled thief could still evade this system with a specially designed device that intercepts the signal.

As you can see there are quite a number of advantages to having a transponder key. All car owners must take this into consideration if they wish to protect their investment and minimize theft risk.

Key Fobs

Key fobs today do more than just lock and unlock doors. They can also start your car remotely, make chirping noises to help locate a car, or switch on the heated steering wheel. A lot of these features may appear convenient but they could make it more difficult to keep track of your car keys.

Key fobs communicate with one other and the car using radio frequencies which are transmitted via an antenna in the center of the key. This communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.

There are several ways to program a key fob based on the make and model. Certain models allow you to do this by yourself. However, most newer models require you to visit an expert 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 inside the car with which it is linked. The receiver compared the information with the permitted signals stored in the key fob, and then opens or locks the car's doors. If the data doesn't match the signals, a chirping sound can be heard and the car isn't permitted to operate.

After the car has been paired with a specific fob, it will only accept signals from the device. Other fobs won't work with the car, despite the fact that they appear similar. This safeguards the integrity of the computer system that runs the vehicle and stops unauthorized key fobs gaining control over it.

The majority of newer dealerships will only deal with cars that have original fobs, or genuine replacements sold by the manufacturer. This is because preparing a replacement fob requires technological and security expertise which can only be obtained in the dealer service department. Certain aftermarket fobs, typically those from older models with less advanced systems, can be programmed without the need for a dealer.
