The key might not function correctly or will not start the vehicle in any way. This is because the key has not yet been programmed into the vehicle's system. This could be costly. It is recommended to have two keys that work with your current car so you can program the replacement key whenever needed.

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

Transponder Chips

If your car key Reprogram was built in the last 20 years, it is likely that it contains a transponder chip within of it. It's a tiny plastic piece on the back of your key that contains an RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.

The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then absorbed by the special antenna that is positioned around the ignition barrel of your vehicle. This allows the vehicle's computer system to confirm that the transponder chip inside the key is the right one for your particular car.

This is the reason why doing hot-wiring or altering the ignition system of the vehicle to start it. The chip in the key also verifies that you are the genuine owner of the vehicle. This will help reduce car theft.

Transponder keys look like normal keys but have caps made of plastic. The chip is housed inside the plastic portion of the key, and there are a few different cuts that can be found on the keys: a cut, a laser cut and program car key (also known as a sidewinder key) or Ford Tibbe key.

The circuit in the induction coil will emit an electrical signal when the transponder is inserted into an ignition barrel. The signal will be taken up by the chip, causing it to transmit a signal to the car. If the car's computer recognizes this signal as the correct one, it will disable the vehicle immobilizer and allow the engine to begin.

If the car doesn't recognize the transponder as being the proper signal, it won't start the engine and will alert you with flashing lights and siren. This function is designed to discourage individuals from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and determined thief could still bypass this system with a specially designed device that detects the signal.

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

Key Fobs

In addition to locking and unlocking doors, starting the car remotely or making noises to aid in finding a car in a parking space, today's key fobs can also activate the heated steering wheel or roll down all of the windows with a single button click. A lot of these features might seem useful but they could make it difficult for you to keep track of your car keys.

Key fobs utilize radio frequencies to communicate with each other and the car. These frequencies are transmitted via a small antenna that is located inside the middle of the key. This communication is encrypted, which helps keep others from stealing and re-transmitting the signal.

Keyfobs can be programmed in different ways based on the make and model of your vehicle. Certain cars let you do this by yourself. However, most newer models require you to visit a professional locksmith or dealer in order to program a replacement key fob or additional one.

When you press a key fob's button it transmits a code to the car's receiver that it is paired with. The receiver then compares this information to the 'allowed' signals in the fob and then either locks or opens the door. If the data does not match the signals, the car will not be allowed to run.

Once the car has been connected to a specific fob, it will only accept signals from that device. Other fobs will not work with the car, even though they appear similar. 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.

The majority of newer dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is because the process of creating a replacement fob requires technological and security skills which can only be obtained in the dealer service department. Some fobs from the aftermarket, especially those for older models with less advanced systems, can be programmed without the need for a dealership.
