There are many kinds of car key programming that can be accomplished by professional locksmiths. Certain types are extremely complex and require sophisticated tools. These tools are generally not available to the general public and are used only by professionals. This type of key programming is called EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.

Transponder Chips

Transponder chips are likely to be found in vehicles manufactured in the last 20 years. It's the small plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.

The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system in the vehicle will then confirm that the key's transponder chip is the right one for your car.

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 sends a signal to the vehicle. If the computer inside the car is able to recognize the signal as valid, it will disable vehicle immobilizer so that the engine can start.

If the car doesn't recognize the transponder as a valid signal, it won't start the engine and alert you with flashing lights and a siren. This feature is designed to deter people from trying to hack into the vehicle, but it isn't a foolproof security measure. A determined and skilled thief can still get around this system with a specially designed device that blocks the signal.

As you can see there are quite number of advantages to having transponder keys. All car key programmers owners should take this into consideration when they want to safeguard their investment and reduce the risk of theft.

Key Fobs

These extra features can make it difficult to locate your car keys.

Key fobs communicate with one other and the car using radio frequencies that are transmitted by an antenna in the center of the key. The signal is encrypted to prevent others from stealing or modifying the signal.

There are a few different ways to program a car key a key fob based on your vehicle's model and make. You may be able to do it yourself, however most modern cars require that you visit a locksmith shop or a professional to program a replacement or a second fob.

When you press a key fob's button it transmits a code to the car's receiver it is paired with. The receiver compares the information with the 'allowed signals' stored on the key fob and then it opens or closes the car's doors. If the information doesn't match the signals, a chirping sound can be heard and the car isn't allowed to operate.

Once the car is paired with a specific fob, it will only receive signals from the device that is associated with it. Other fobs won't work with the car, even though they look similar. This safeguards the integrity of the computer system in the car and blocks unauthorised key fobs from taking control of it.

Most newer car dealers will only work on cars with original fobs or genuine replacements offered by the manufacturer. This is because the only place that has the knowledge to create the replacement fob is the service department of a dealer. Some aftermarket fobs, usually those from older models that have less sophisticated systems can be programmed without the need for a dealership.
