Key Programmers

Modern automobiles require a key-programming process to start the vehicle's system and start the car. In some instances, the key will need to be programmed by an auto locksmith or a dealer. This is because the key may not work properly or start the vehicle at all. This is because the key hasn't yet been programmed into the vehicle's system. This could be costly. This is why it's a good idea to always have two working keys for a modern automobile and have the replacement key programmed if required.

Keyprogrammers can recode the transponder chip of the new mechanical key or key fob. It is also able to copy data from an existing key to make 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 as well as an interface that works bidirectionally with the immobilizer system.

There are a number of different types of keyprogrammers available that are available and they come in all shapes and sizes. Some are cheap and others are advanced and could cost thousands of dollars. Some are designed for specific types of vehicles and can offer advanced diagnostics for the car's electronic systems.

Transponder Chips

If your car was built within the past 20 years, then it contains a transponder chip within of it. This is the little piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.

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

This is the reason why doing hot-wiring or altering the ignition system of the vehicle to get it started. The chip in the car key confirms that the owner is the person who owns the vehicle. This can reduce car theft.

Transponder keys appear like regular metal keys but they have a plastic cap. The chip is inside the plastic part of these keys. There are a variety of cuts that are a standard cut, a Laser cut (also known as a sidewinder or Ford Tibbe) and a Ford Tibbe.

A circuit within the induction coil emits signals when the transponder is inserted into an ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer on the car recognizes this signal as the right one, it will shut down the vehicle immobilizer and allow the engine to begin.

If the vehicle doesn't recognize the transponder signal as being the correct one, it will keep the engine from running and will alert you by flashing its lights and sounding siren. This feature is designed to discourage people from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and determined thief could still be able to get around this system employing a device designed to take over the signal.

You can see that a transponder is a great option. This is something that all car owners should consider if want to safeguard their investment and minimize the chance of theft.

Key Fobs

Key fobs today can offer more than locking and unlock doors. They can also turn on the vehicle remotely, make chirping noises to aid in finding the car or switch on the heated steering wheel. Many of these extra features might seem useful but they could make it difficult for you to keep track of your car keys.

Key fobs communicate with one other and the car using radio frequencies which are transmitted through an antenna in the center of the key. This communication is encrypted to stop others from intercepting or replicating the signal.

You can program a keyfob in a variety of ways depending on the model and make of your vehicle. Certain cars let you do it yourself. However, most newer models require you to visit a professional locksmith or dealer in order for them program a replacement key programmer fob or additional one.

When you press the button on a key fob the microchip transmits an indication to the receiver in the vehicle with which it is paired. The receiver then compares the data with the 'allowed signals' stored in the key fob and then locks or opens the car's doors. If the data doesn't match, a chirping sound is heard and the car isn't allowed to operate.

Once the car is associated with a particular fob, it only accepts signals from that device. In turn, other fobs won't work with the vehicle even if they look the same. This helps to protect the integrity of the car's computer system and prevent unauthorized key fobs from gaining control of the vehicle.

Most newer car dealerships will only accept cars with original fobs or genuine replacements sold by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security expertise which can only be obtained in the dealer service department. However, some aftermarket fobs typically for older models that have less sophisticated systems -- can be programmed by consumers without the need of a dealership.
