Keyprogrammers are devices that recodes the transponder chip in the form of a new key fob or mechanical key. It can also clone the data from an existing key and allow duplicate keys to be created. These are handheld devices that connect to the car's On Board Diagnostics (OBD port).

Transponder Chips

Transponder chips can be found in cars manufactured in the last 20 years. This is the little plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.

When it is activated by an electro-magnetic field the chip emits a low-frequency signal. This signal is then taken up by an antenna attached to the ignition barrel. This allows the vehicle's computer system to confirm that the transponder chip that is in the key is the correct one for the car you have.

This is the reason why doing hot-wiring or altering the ignition system of your vehicle to turn it on. The chip in the car key verifies that the owner is the person who is the owner of the vehicle. This will help reduce the possibility of theft from your vehicle.

Transponder keys resemble regular keys made of metal but have a plastic cap. The chip is housed in the plastic portion of the key, and there are different cuts that can be found on these keys: a cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out a signal. The signal will be received by the chip and cause it to send a signal back to the car. If the car's computer recognizes this signal as being the correct one, it will disable the vehicle immobilizer and allow the engine to begin.

If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and will alert you with flashing lights and siren. This system is designed to deter individuals from tampering with the vehicle. However it isn't a foolproof measure of security. A skilled and committed thief may still be able to get around this system using a special device to intercept the signal.

As you can see there are quite few advantages to getting a transponder key. This is something that all car owners should consider if are looking to safeguard their investment and reduce the risk of theft.

Key Fobs

Key fobs today can do more than just lock and unlock doors. They can also start the car from a distance, make chirping sounds to aid in finding cars, or turn on the heated steering wheel. These additional features can make it difficult for you to find your car keys.

Key fobs use radio frequencies to communicate with each other and the car. These frequencies are sent via a small antenna that is located inside the middle of the key. The signal is encrypted to prevent others from stealing or stealing the signal.

Keyfobs can be programmed in different ways based on the model and make of your car. It is possible to do this yourself, but most newer automobiles require a dealer or professional locksmith to program a replacement or a second fob.

When you press the button on a key fob, the microchip sends signals to the receiver inside the vehicle with which it is linked. The receiver compares this information to the 'allowed' signals on the fob and either locks or opens the door. If the information does not match the fob's information, the car won't be allowed to operate.

Once the car is linked with a specific fob, it will only accept signals from that specific device. This means that other fobs won't be able to work with the vehicle even though they look the same. This protects the integrity of the computer system in the car and blocks unauthorized key fobs gaining control over it.

The majority of newer dealerships will only accept vehicles that have original fobs, or genuine replacements supplied by the manufacturer. It is because the only place with the knowledge to create a replacement fob is in a dealer's service department. Certain aftermarket fobs, typically those for older models with less sophisticated systems, can be programmed without the need for a dealership.
