It requires expertise in soldering, electronic knowledge and a lot time.

Transponder Chips

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

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

This stops the vehicle from starting by either hot-wiring or by altering the key. The chip inside the key also confirms that you are the legal owner of the vehicle. This can reduce car theft.

Regular transponder keys are shaped like regular keys, but with a plastic top. The chip is contained in the plastic portion of the key, and there are a few different types of cuts on the keys: a standard cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal is received by the chip which then transmits a signal to the vehicle. If the onboard car computer recognizes this signal as the correct one, it will disable the immobilizer on the vehicle and allow the engine to begin.

If the vehicle doesn't recognize the transponder signal as the proper one, it will prevent the engine from running and will notify you by flashing its lights and sounding an alarm. This feature is designed to deter people from trying to tamper with the vehicle, but it's not a 100% security measure. A skilled and determined thief might be able get around this system using a device that can take over the signal.

A lot of these additional features may seem convenient but they could make it harder for you to keep the keys to your mobile car key programming.

Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are transmitted via a small antenna that is located in the middle of the key. The transmission is encrypted, which helps to keep others from stealing and retransmitting the signal.

There are many ways to program a key fob, based on the make and model. Some cars allow you to do it yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order to program a replacement key fob or additional one.

When you press the button on a key fob the microchip sends an indication to the receiver in the vehicle with which it is paired. The receiver compared the information with the 'allowed signals' that are stored on the key fob and then it opens or closes the car door. If the information doesn't match the fob's information, the car won't be allowed to run.

Once the car key cut and program has been associated with a particular fob, it will only accept signals from that device. Other fobs will not work with the car, even though they look identical. This safeguards the integrity of the computer system in the car and prevents the use of unauthorized key fobs to gain control of it.

The majority of newer dealerships will only deal with cars with original fobs, or genuine replacements sold by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security knowledge that can only be found in the dealer service department. However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by the consumer without the need for dealers.
