Modern models come with computers that offer improved anti-theft protection. These cars require a transponder-chip-integrated key to be programmed by a professional locksmith car dealer or mechanic to function properly.
There are a few different types of car key programming that can be done by professional locksmiths. Some are very complex and require sophisticated tools. These tools are usually not available to the general public and are used only by professionals. This type of programming keys is known as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot of time.
Other types of key programming can be done by anyone. They are accomplished using the onboard diagnostic port, which can be accessed with a special tool for key fob programming. This procedure can be carried out by a professional locksmith using an online guide or the vehicle's owner's manual.

Key Programmers
Modern vehicles require a key-programming procedure to start the vehicle's system and then start the vehicle. In some cases the key will have to be programmed by an auto locksmith or a dealer. The key may not work properly or not start the car in any way. This is because the key has not yet been programmed into the car's system. This could be costly. This is why it's a great idea to always have two working keys for a modern automobile, so you can get the replacement key programmed if required.
A keyprogrammer can reprogram the transponder key programmer chip of the new mechanical key or key fob. It can also clone the data of an existing key which allows duplicate keys to be made. 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. They also feature a bidirectional user interface that works with an immobilizer system.
There are many different types of keyprogrammers available that are available, and they come in a variety of sizes and shapes.

These are less expensive than going to the dealership however, they're not cheap. Before you purchase one do some research on the seller. Some are not reliable and may damage your vehicle.
Transponder Chips
If your car was manufactured in the past 20 years, chances are it has a transponder inside of it. This is the little plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your car key programer.
When activated by an electro-magnetic field the chip emits a low level signal. This signal then gets amplified by the specific antenna that is positioned around the barrel that controls your ignition in your vehicle. This allows the car's computer system to determine if the transponder chip that is in the key is the correct one for the car you have.
This is the reason why doing hot-wiring or altering the vehicle's ignition system to turn it on. The chip inside the key also proves that you are the genuine owner of the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular metal keys with a plastic top. The chip is contained within the plastic portion of these keys. There are several different cuts: a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.
A circuit within the induction coil will emit signals when the transponder is inserted into the ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the onboard car computer detects this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to start.
If the car does not recognize the transponder signal as the right one, it will stop the engine from starting and will alert you by flashing its lights and sounding siren. This system is designed to deter individuals from tampering with the vehicle. However, it is not an unbreakable security measure. A skilled and determined thief could still evade this system using a special device that intercepts the signal.
It is evident that the transponder is a good option. This is something that all car owners should think about if they want to protect their investment and minimize 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 lot, today's key fobs can also turn on the heated steering wheel or roll down all of the windows with just a single click. Many of these extra features might seem useful however they could make it more difficult to keep track of your car keys.
Key fobs make use of radio frequencies to communicate with one another and the car. These frequencies are sent by a small antenna within the middle of the key. The transmission is encrypted, which helps to stop others from stealing and replicating the signal.
You can program a keyfob in a variety of ways depending on the model and brand of your car. Certain cars let you do it yourself. However, most newer models require you to visit a professional locksmith or dealer for them program a replacement key fob or additional one.
When you hit the button on a key fob the microchip inside sends an encoded code to the car's receiver it is paired with. The receiver compares the information with the 'allowed signals' that are stored in the key fob, and then locks or opens the car door. If the data does not match the signals, the car will not be allowed to run.
After the car has been connected to a specific fob, it can only receive signals from that device. This means that other fobs won't be able to work with the vehicle even though they appear similar. This ensures the security of the computer system in the car and prevents unauthorised key fobs from taking control of it.
Most newer car dealerships will only deal with cars that have original fobs or genuine replacements offered by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise which can only be obtained in the dealer's service department. Some fobs from the aftermarket, especially those for older models that have less advanced systems can be programmed with out the need for a dealer.
