Modern models come with computers that are enhanced security against theft. In order to work correctly, these vehicles require that a transponder chip key be programmed into the vehicle by a professional locksmith or a car dealer/mechanic.
Professional locksmiths can carry out a variety of different types of programming for keys for cars. Certain types are more complex and require specialized tools. These tools are usually not available to the general public and are used only by professionals. This kind of programming for car keys is referred to as EEPROM Programming and requires soldering, electronic expertise, and a lot of time.
Other kinds of key programming can be performed by anyone. These are usually done by using the onboard diagnostics port, which is accessible with a special key-fob-programming tool. Locksmiths can execute this procedure with the help of a guide online and the owner's manual.

Key Programmers
Modern automobiles often require a key programming process to start the system of the vehicle and allow the vehicle to start. In some instances 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 good idea to have two keys that work for a modern car and have the replacement key programmed if required.
A keyprogrammer can reprogram the transponder chip on an entirely new mechanical key or key fob. It is also able to copy the data from an existing key, allowing duplicates to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that allows them to communicate with computers as well as bidirectional interfaces to work with the immobilizer system.
There are a myriad of types of keyprogrammers that are available on the market. They are available in a variety of sizes, shapes and colors. Some are affordable, while others are very sophisticated and can cost thousands of dollars. Some are specifically designed for certain types of vehicles, and they can even offer advanced diagnostics for the car's electronic systems.
If you're looking to program a new key to your vehicle, consult the owner's manual to find out how to do it. Some manufacturers use proprietary software that only permits the dealership to create new keys. Other manufacturers make it simple for anyone to do.

They are less expensive than visiting a dealer, but still not expensive. Make sure you look up the seller before buying one. Some aren't reliable and could damage your car.
Transponder Chips
If your car was manufactured in the past 20 years, it is likely that it contains a transponder chip within of it. It's the tiny plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your car.
When it is activated by an electromagnetic field, the chip emits a low level signal. This signal is then amplified by the specific antenna that is attached to the ignition barrel of your car. The computer system in the vehicle will then confirm that the chip in the key's transponder is the correct one for your car.
This stops the vehicle from starting by hot-wiring or manipulating. The chip in the key also confirms that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are shaped like regular metal keys with a plastic top. The chip is contained within the plastic portion of these keys. There are various cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe) and Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal will then get taken up by the chip and cause it to transmit a signal back to the car. If the computer in the car recognizes the signal as correct, it will disable vehicle immobilizer to allow the engine start.
If the car does not recognize the transponder signal as being the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding an alarm. This system is designed to deter people from tampering with the vehicle. However it isn't an unbreakable security measure. A skilled and determined criminal could still be able to bypass this system by employing a device designed to take over the signal.
You can see that a transponder is a great option. This is something that all vehicle owners should consider if they want to safeguard their investment and decrease the chance of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely or making noises to aid in finding the car in a parking lot Key fobs today can also activate a heated steering wheel, or roll down all of the windows with a single button push. These extra features can make it difficult to locate your car keys.
Key fobs communicate with one with the car via radio frequencies which are transmitted by an antenna in the middle of the key. The signal is encrypted to stop others from stealing or stealing the signal.
You can program a keyfob in a variety of ways depending on the model and brand of your vehicle. car key programming can sometimes do this yourself, but the majority of newer automobiles require a locksmith shop or a professional to program a replacement or additional fob.
When you hit the button on a key fob the microchip inside sends a code to the car's radio that it is paired with. The receiver compared this information with the signals that are allowed in the fob and then either opens or closes the door. If the data doesn't match, a chirping sound is heard and the car isn't able to operate.
Once the car is paired with a particular fob, it will only receive signals from that device. This means that other fobs will not work with the vehicle, even though they look the same. This safeguards the integrity of the computer system that runs the car and blocks the use of unauthorized key fobs to gain control of it.
Most newer car dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security knowledge that can only be found in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed by the consumer without the need of a dealership.
