Modern models come with computers that have improved anti-theft protection. The cars require a transponder chip-integrated key to be programmed by a professional locksmith mechanic or dealer for proper operation.

These tools are generally not available to the general public and are used only by professionals. This type of programming for car keys is known as EEPROM Programming and requires soldering, electronic skills, and a lot of time.

Key Programmers

Modern automobiles typically require a key programming procedure to initialize the vehicle's system and allow the vehicle to start. In some instances keys must be programmed by the dealer or auto locksmith. This is because the key could not function properly, or it will not start the vehicle in any way. The reason for this is that the new key has not been programmed to the car's system, and this could be quite expensive. This is why it's a great idea to have two keys that work for modern vehicles, so you can get the replacement key programmed if necessary.

A keyprogrammer can reprogram the transponder chip on the new mechanical key or key fob. It is also able to copy the data from an existing key which allows duplicate keys to be created. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that allows them to communicate with computers as well as bidirectional interfaces to work with the immobilizer system.

Transponder Chips

Transponder chips are likely be found in cars that were manufactured within the last 20 years. It's a tiny piece of plastic on the back of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.

When it is activated by an electromagnetic field the chip emits a low-frequency signal. This signal then gets amplified by the specific antenna that is positioned around the ignition barrel of your vehicle. This allows the car's computer system to confirm that the transponder chip that is in the key is the right one for your particular car.

This stops the vehicle from being started by hot-wiring, or by manipulating. The chip inside the key ensures that the owner is the person who is the owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.

Regular transponder keys are shaped like regular keys and have a plastic top. The chip is contained within the plastic part of the keys. There are several different cuts such as a standard cut Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.


A circuit within the induction coil emits an electrical signal when the transponder is put into ignition barrel. The signal will be received by the chip, causing it to transmit a signal back to the car. If the computer inside the car detects the signal as correct, it will disable vehicle immobilizer, allowing the engine to start.

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 intended to deter people from trying to alter the vehicle, however it's not a 100% security measure. A determined and skilled thief could still bypass this system using a special device that detects the signal.

You can see that the transponder is a good option. This is something that all car owners should consider if want to protect their investment and reduce the risk of theft.

Key Fobs

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

Key fobs utilize radio frequencies to connect with one another and with the car. These frequencies are sent by a small antenna in the middle of the key. This communication is encrypted to block other key fobs from intercepting or replicating the signal.

There are a few different ways to program a key fob, based on the vehicle's model and make. Certain cars let you do this by yourself. However, most newer models require you to visit an expert locksmith or dealer in order to program a new key fob, or an alternative one.

When you press the button on a key fob the microchip sends signals to the receiver inside the vehicle that it is paired. The receiver compares this information to the 'allowed' signals stored inside the fob, and either opens or closes the door. If the information doesn't match the signals, the car will not be allowed to run.

Once the car is paired with a specific fob, it will only accept signals from that specific device. Other fobs won't work with the car, despite the fact that they look similar. This protects the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.

Most newer car dealerships will only accept vehicles that have original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security skills that can only be found in the dealer's service department. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems can be programmed by customers without the need for an authorized dealer.
