The cars require a transponder chip-integrated key to be programmed by a professional locksmith, mechanic or dealer to function properly.

These tools are usually not available to the general public and are only used by professionals. This type of car key programming is referred to as EEPROM Programming and requires soldering, electronic skills and a lot of time.

Other kinds of programming car keys are much easier and can be performed by anyone who is able to.

Key Programmers

Modern cars require a key-programming process to initialize their vehicle's systems and then start the vehicle. In certain instances, the key will need to be programmed by an auto locksmith or a dealer. This is because the key may not function properly, or it will not start the vehicle at all. This is because the new key has not been programmed to the car's system. This can be quite costly. This is why it's a great idea to have two working keys for modern vehicles, so you can get the replacement key programmed if necessary.

A keyprogrammer is a device which can reprogram the transponder chip into an entirely new key fob or mechanical key. It is also able to copy information from an existing key to create duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with the computer as well as bidirectional interfaces to work with the immobilizer system.

There are many different types of keyprogrammers available on the market. They come in all sizes, shapes, and colors.

Transponder Chips

If your car was manufactured within the past 20 years, it is likely that it has a transponder inside of it. It's a small piece of plastic on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.

The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal is then taken up by an antenna attached to the ignition barrel. The computer system in the vehicle will then confirm that the transponder chip of the key is the correct one for your vehicle.

This is what prevents hot-wiring or tampering with the ignition system of the vehicle to get it started. The chip in the key also proves that you are the genuine owner of the vehicle. This can help to reduce car theft.

Transponder keys appear like regular metal keys but they have caps made of plastic. The chip is located inside the plastic part of these keys. There are various cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe), and a Ford Tibbe.

The circuit in the induction coil emits an electrical signal when the transponder is placed in the the ignition barrel. The signal will then get received by the chip, causing it to transmit a signal to the car. If automotive key programming is able to recognize the signal as valid it will turn off the vehicle immobilizer to allow the engine start.

If the vehicle doesn't recognize the transponder signal as being the right one, it will stop the engine from starting and will notify you by flashing its lights and sounding an alarm. This system is designed to deter those who would attempt to alter the vehicle. However, it is not a foolproof measure of security. A determined and skilled thief can still get around this system with a specially designed device that intercepts the signal.

You can see that the transponder is an excellent option. This is something that all vehicle owners should consider if are looking to safeguard their investment and decrease the chance of theft.

Key Fobs

In addition to locking and unlocking doors, starting the car remotely or making chirping sounds to help find a car in a parking space keys of today can also activate a heated steering wheel or open all windows with just a single push. These extra features could make it difficult to locate your car keys.

Key fobs use radio frequencies to communicate with one another and the car. The frequencies are transmitted via a small antenna that is located in the middle of the key. The transmission is encrypted, which helps keep others from stealing and retransmitting the signal.

You can program a keyfob in various ways based on the make and model of your car. Some cars allow you to do it yourself. However, most newer models require you to visit an expert locksmith or dealer for them program a replacement key fob, or an alternative one.

When you press the button on a key fob, the microchip transmits a signal to the receiver inside the car that it is paired. The receiver compared this information with the 'allowed' signals stored on the fob and either opens or locks the door. If the information does not match the fob's information, the car won't be allowed to drive.

After the car has been connected to a specific fob, it only accepts signals from that device. This means that other fobs will not work with the vehicle even though they have the same appearance. This protects the integrity of the computer system in the vehicle and stops unauthorised key fobs from taking control over it.

Most newer car dealerships will only work with cars that have original fobs, or genuine replacements supplied by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security knowledge that is only available in the dealer's service department. Certain aftermarket fobs, typically those from older models with less sophisticated systems can be programmed with out the need for a dealer.
