These tools aren't generally accessible to the general public and are utilized only by professionals. This type of car key programming is known as EEPROM Programming and requires soldering, electronic skills and a significant amount of time.

This way, you can ensure that the new key is programmed to your vehicle and that it will work. You will have to pay the dealer for programming and replacement keys if they don't.

A keyprogrammer is a tool that recodes the transponder chip on an entirely new key fob or mechanical key. It is also able to copy the data of an existing key which allows duplicate keys to be made. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with computers. They also have a bidirectional interface that works with an immobilizer system.

Transponder Chips

Transponder chips are likely to be found in cars manufactured within the last 20 years. It's the small plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your car.

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

This stops the vehicle from being started by hot-wiring or altering the key. The chip in the key also confirms that you are the genuine owner of the vehicle. This will help reduce the possibility of theft from your vehicle.

Transponder keys appear like normal keys, but with a plastic cap. The chip itself is housed inside the plastic portion of the key, and there are a few different cuts that can be found on these keys: a regular cut laser cut (also called a sidewinder) or Ford Tibbe key.

A circuit within the induction coil will emit signals when the transponder is placed in the ignition barrel. The signal will then get taken up by the chip, causing it to transmit a signal to the car. If the onboard car computer recognizes this signal as being the correct one, it will turn off 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 siren. This feature is designed to discourage those who would attempt to alter the vehicle. However, it is not a foolproof measure of security. A skilled and committed thief could still be able to get around this system employing a device designed to take over the signal.

As you can see there are quite a number of advantages to having a transponder key. All car key cutting and programming owners must take this into consideration when they want to safeguard their investment and reduce the chance of theft.

Key Fobs

Key fobs today offer more than locking and unlock doors. They can also start your car remotely, emit chirping sounds to aid in finding a car, or switch on the heated steering wheel. These additional features can make it difficult to find your car keys.

Key fobs utilize radio frequencies to communicate with one another and the car. The frequencies are transmitted via a small antenna that is located within the middle of the key. This communication is encrypted to stop others from intercepting or replicating the signal.

You can program a keyfob in various ways based on the make and model of your vehicle. You may be able to do it yourself, but most newer cars require that you visit a locksmith shop or a professional to program a replacement or additional fob.

When you hit the button on a key fob it transmits a code to the car's receiver it is linked to. The receiver compares this information with the 'allowed' signals on the fob and either opens or locks the door. If the information doesn't 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 that device. In turn, other fobs won't be able to work with the vehicle even though they have the same appearance. This protects the integrity of the car's computer system and to prevent the use of unauthorized key fobs to gain control of the vehicle.

The majority of newer dealers will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. The reason for this is that the only place with the experience to design the replacement fob is a dealer's service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed by customers without the need of dealers.
