These tools are usually not available to the general public and are only used by professionals. This type of programming is known as EEPROM Programming.

This is because the new key has not been programmed into the vehicle's system - and this can be quite expensive. This is why it's a great idea to always have two keys that work for a modern automobile and have the replacement key programmed if needed.

A keyprogrammer can recode the transponder chip on an entirely new mechanical key or key fob. It also can clone information from an existing key in order to create duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software, which allows them to communicate with computers. They also have a bidirectional interface for working with an immobilizer system.

Transponder Chips

Transponder chips are likely to be found in cars that were manufactured within the past 20 years. This is a little piece of plastic in the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.

When activated by an electro-magnetic field, the chip emits a low level signal. The signal is taken up by an antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to determine if the transponder chip in the key is the right one for your particular car.

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

Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is located inside the plastic part of these keys. There are various cuts such as a standard cut a Laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal will be received by the chip and program keys for cars cause it to transmit a signal back to the car. If the computer inside the car detects the signal as correct it will turn off the car immobilizer to allow the engine start.

If the vehicle doesn't recognize the transponder as the correct signal, it won't start the engine and will notify you via flashing lights and an alarm. This feature is designed to discourage individuals from tampering with the vehicle. However, it is not an absolute security measure. A skilled and determined criminal could still be able to escape this security system by using a device that can take over the signal.

It is evident that the transponder is an excellent option. Every car owner should take this into consideration when they want to safeguard their investment and decrease the risk of theft.

Key Fobs

In addition to locking and unlocking doors, starting the car remotely, or making noises to aid in finding the car in a parking space keys of today can also activate the heated steering wheel or roll down all windows with a single click. These additional features can make it difficult for you to find your car keys.

Key fobs communicate with one other and the car using radio frequencies that are transmitted through an antenna in the center of the key. The communication is encrypted, which helps keep others from stealing and replicating the signal.

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

When you press the button on a key fob the microchip transmits an indication to the receiver in the car that it is paired. The receiver compared this information to the 'allowed' signals stored on the fob and either locks or opens the door. If the information isn't in line an chirping sound is heard and the car isn't allowed to function.

Once the car is linked with a particular fob, it will only receive signals from that specific device. This means that other fobs won't work with the vehicle even though they appear similar. This safeguards the integrity of the computer system that runs the car and prevents unauthorised key fobs from taking control over it.

Most newer car dealerships will only deal with vehicles that have original fobs, or genuine replacements offered by the manufacturer. The reason for this is that the only place that has the experience to design the replacement fob is the service department of the dealer. 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 a dealership.
