In order to work correctly, these vehicles require a transponder chip-integrated key be programmed to the vehicle by a certified locksmith or a car dealer/mechanic.

There are several types of car key programming that can be done by locksmiths who are professionals.  programming keys  are complex and require advanced tools. These tools are usually not available to the general public and are used only by professionals. This kind of programming is known as EEPROM Programming.

Key Programmers

Modern automobiles require a key-programming procedure to initialize their vehicle's systems and to start the car. In many cases, the key must be programmed by the auto locksmith or dealer. The key may not work properly or it may not even start the vehicle in any way. This is because the key hasn't yet been programmed into the vehicle's system. This can be costly. This is why it's a great idea to always have two keys working for a modern automobile and to have the replacement key programmed if needed.

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

There are a number of different kinds of keyprogrammers on the market and they come in a variety of sizes and shapes. Some are inexpensive and others are advanced and can cost thousands of dollars. Some are made for specific automobiles and offer advanced diagnostics of the car's electronic system.

Transponder Chips

Transponder chips can be found in cars manufactured within the past 20 years. This is a little plastic thing in the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.

When it is activated by an electromagnetic field, the chip emits a low level signal. The signal is then taken up by the antenna that is attached to the ignition barrel of your vehicle. The computer system in the vehicle is then able to 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 tampering. The chip inside the key also verifies that you are the legal owner of the vehicle. This will help reduce the possibility of theft from your vehicle.

Transponder keys look like regular keys made of metal but have a plastic cap. The chip is contained in the plastic portion of the key and there are a few different kinds of cuts available on the keys: a standard cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the onboard car computer detects this signal as the right one, it will turn off the vehicle's immobilizer and allow the engine to begin.

If the vehicle does not recognize the transponder signal as being the proper one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This is designed to discourage people from attempting to tamper with the vehicle, but it's not a 100% security measure. A skilled and skilled criminal could still evade this system using a special device that intercepts the signal.

It is evident that the transponder is a good option. All car owners should take this into consideration if they wish to protect their investment and minimize theft risk.

Key Fobs

In addition to locking and unlocking doors, launching the car from a distance or making chirping sounds to help find the car in a parking lot keys of today can also turn on the heated steering wheel or roll down all windows with a single click. These extra features can make it difficult for you to locate your car keys.

Key fobs communicate with each with the car via radio frequencies that are transmitted by an antenna that is located in the middle of the key. This communication is encrypted to block other key fobs from stealing or modifying the signal.

Keyfobs can be programmed in a variety of ways depending on the make and model of your vehicle. It is possible to do this yourself, however most modern vehicles require a dealer or professional locksmith to program a replacement or additional fob.

When you press the button on a key fob the microchip transmits a signal to the receiver in the car that it is paired. The receiver compared this information to the  signals that are allowed in the fob and then either opens or locks the door. If the information does not match the signals, the car will not be allowed to operate.

Once the car is paired with a particular fob, it will only receive signals from the device that is associated with it. As a result, other fobs won't work with the vehicle even though they have the same appearance. This helps to protect the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.

The majority of newer dealerships will only deal with cars that have original fobs or genuine replacements offered by the manufacturer. It is because the only place that has the knowledge to create a replacement fob is in a dealer's service department. Some aftermarket fobs, usually ones for older models that have less sophisticated systems can be programmed without the need for a dealer.
