Key Programmers

The key might not function properly or it may not even start the vehicle 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 costly. It is recommended to have two keys that are compatible with your current car so you can program the replacement key when required.

Keyprogrammers can recode a transponder chip on the new mechanical key or key fob. It is also able to copy information from an existing key to make duplicates.

Transponder Chips

Transponder chips can be found in vehicles manufactured within the past 20 years. It's the small plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to your reprogram car key.

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

This stops the vehicle from starting by hot-wiring or altering the key. The chip inside the key confirms that the owner is the person who is the owner of the vehicle. This will help reduce car theft.

Regular transponder keys are shaped like regular keys, but with a plastic top. The chip itself is housed within the plastic part of the key, and there are different cuts that can be found on these keys: a standard cut laser cut (also known as a sidewinder key) or Ford Tibbe key.

The circuit in the induction coil will emit a signal when the transponder key programming is put into ignition barrel. The signal will be received by the chip and cause it to send a signal back to the car. If the computer on the car recognizes this signal as being the right one, it will turn off the vehicle's immobilizer and allow the engine to begin.

If the car doesn't recognize the transponder as a valid signal, it will not start the engine and warn you with flashing lights and an alarm. This feature is designed to discourage people from tampering with the vehicle. However it isn't an absolute security measure. A skilled and determined criminal could still be able to escape this security system by using a device that can detect the signal.

You can see that the transponder is a good option. Every car owner should consider this when they want to safeguard their investment and reduce the risk of theft.

Key Fobs

Key fobs today do more than just lock and unlock doors. They can also start the vehicle from a distance, make chirping sounds to aid in finding the car or switch on the heated steering wheel. These extra features could make it difficult to locate your car keys.

Key fobs communicate with one other and the car using radio frequencies that are transmitted through a small antenna located in the center of the key. This signal is encrypted to prevent others from stealing or stealing the signal.

You can program a keyfob in various ways based on the model and brand of your car. You may be able to do it yourself, however most modern automobiles require a locksmith shop or a professional to program a replacement or a second fob.

When you hit the button on a key fob it transmits a code to the car's radio that it is linked to. The receiver compared this information to the 'allowed' signals stored in the fob and then either opens or locks the door. If the information does not match the fob's information, the car won't be allowed to drive.

Once the car has been paired with a specific fob, it will only accept signals from that device. This means that other fobs won't work with the vehicle even though they look the same. This protects the integrity of the vehicle's computer system and to prevent unauthorised key fobs from taking control of the vehicle.

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