There are a few different kinds of car key programming that can be done by locksmiths who are professionals. Some are very complex and may require advanced tools. These tools are generally not available to the general public and are only used by professionals. This kind of programming is known as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a significant amount of time.

Other kinds of programming for car keys are a lot simpler and can be performed by the average person. They are typically done using the diagnostics port on the car, which is accessible with the key-fob-programming device.

This is because the key has not yet been programmed into the vehicle's system. This could be costly. This is why it's a good idea to always have two working keys for modern vehicles and have the replacement key programmed when necessary.

A keyprogrammer can recode the transponder chip of the new mechanical key or key fob. It can also clone the data of an existing key to create duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with computers, and they also have bidirectional interfaces to work with the immobilizer system.

There are many different types of keyprogrammers that are available on the market. They are available in a variety of sizes, shapes and colors.

Transponder Chips

If your car is made within the last 20 years, chances are it contains a transponder chip within of it. It's a small plastic thing inside the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.

When it is activated by an electromagnetic field the chip emits a low-level signal. The signal is then received by a specific antenna attached to the ignition barrel. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the right one for your vehicle.

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 legal owner of the vehicle. This will help reduce car theft.

Transponder keys resemble normal keys but have caps made of plastic. The chip is contained in the plastic portion of the key and there are different kinds of cuts available on these keys: a regular cut, a laser cut (also called a sidewinder) or Ford Tibbe key.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out a signal. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the car's computer recognizes this signal as the right one, it will shut down the vehicle immobilizer and allow the engine to start.

If the vehicle doesn't recognize the transponder signal as the correct one, it will stop the engine from starting and will alert you by flashing its lights and sounding an alarm. This feature is intended to deter people from trying to tamper with 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 intercepts the signal.

You can see that the transponder is an excellent option. All car owners must take this into consideration if they wish to protect their investment and reduce theft risk.

Key Fobs

In addition to locking and unlocking doors, starting the car remotely or making sound chirps to help locate the car key cut and programed in a parking lot, today's key fobs can also activate a heated steering wheel or open all windows with just a single press. These additional features could make it difficult to find your car keys.

Key fobs communicate with one other and the car using radio frequencies that are transmitted through an antenna that is located in the center of the key. This signal is encrypted to block other key fobs from stealing or stealing the signal.

You can program a keyfob in a variety of ways depending on the make and model of your vehicle. Some cars allow you to do this yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a replacement key fob or an additional one.

When you press the button on a key fob the microchip sends a signal to the receiver inside the vehicle with which it is linked. The receiver compared the information with the permitted signals stored on the key fob and then locks or opens the car's door. If the information isn't in line, a chirping sound is heard and the car isn't able to function.

Once the car has been associated with a particular fob, it only accepts signals from the device. Other fobs won't work with the car, even though they appear identical. This protects the integrity of the computer system of the vehicle and stops unauthorized key fobs gaining control over it.

The majority of newer dealerships will only accept cars with original fobs or genuine replacements sold by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security skills that can only be found in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems can be programmed by consumers without the need of dealers.
