The latest models come with computer systems that are more secure against theft. The cars require a transponder chip-integrated key to be programmed by a professional locksmith, mechanic or dealer to function properly.
There are a few different kinds of car key programming that can be performed by locksmiths who are professionals. Certain are complicated and require specialized tools. These tools are usually not accessible to the general public and are used only by professionals. This kind of programming for car keys is known as EEPROM Programming and requires soldering, electronic knowledge and a lot of time.
Other kinds of key programming can be carried out by anyone. These are usually done by using the diagnostics port on the car, that can be accessed using a special key-fob-programming tool. This method can be done by a locksmith who is trained with the help of an online guide or an owner's manual.

Key Programmers
Modern automobiles require a key-programming procedure to set up their systems and to start the car. In some instances keys must be set up by the dealer or auto locksmith. This is because the key may not function properly, or it will not start the car at all. This is because the new key has not been programmed to the automobile's system. This can be very costly. It is recommended to have two keys that are compatible for the modern automobile so that you can program the replacement key when required.
A keyprogrammer is a device which can reprogram the transponder chip into the form of a new key fob or mechanical key. It also can clone data from an existing key to make duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software, which allows them to communicate with a computer. They also have a bidirectional interface for working with an immobilizer system.
There are many different types of keyprogrammers available on the market. They come in all shapes, sizes and colors. Some keyprogrammers are cheap, while others may cost thousands of dollars.

They are less expensive than going to a dealership but they aren't inexpensive. Make sure you investigate the seller prior to purchasing one - some are not reliable and could harm your car.
Transponder Chips
If your car is made in the past 20 years, it is likely that it contains a transponder chip within of it. It's a small plastic piece on the back of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
When it is activated by an electro-magnetic field the chip emits a low level signal. The signal is received by a specific antenna that is attached to the barrel of ignition. reprogramming a car key of the vehicle is then able to verify that the key's transponder chip is the right one for your vehicle.
This stops the vehicle from being started by hot-wiring or tampering. The chip in the key also verifies that you are the legal owner of the vehicle. This will help reduce car theft.
Transponder keys appear like normal keys but they have caps made of plastic. The chip is housed inside the plastic portion of the key, and there are a few different cuts that can be found on the keys: a cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
A circuit inside the induction coil will emit signals when the transponder is placed in the ignition barrel. The signal will then get absorbed by the chip and cause it to send a signal back to the car. If the computer onboard the car recognizes the signal as correct it will turn off the car immobilizer, allowing the engine to start.
If the car isn't able to recognize the transponder as being the proper signal, it won't start the engine and will warn you with flashing lights and siren. This feature is intended to discourage people from trying to tamper with the vehicle, however it is not a foolproof security measure. A determined and skilled thief can still get around this system by using a specific device that intercepts the signal.
You can see that the transponder is an excellent option. This is something that all vehicle owners should think about if they want to protect their investment and decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making sound chirps to help locate the car in a parking space Key fobs today can also switch on a heated steering wheel or roll down all of the windows with a single push. These extra features could make it difficult to locate your car keys.
Key fobs make use of radio frequencies to communicate with each other and with the car. These frequencies are sent by a small antenna within the middle of the key. The transmission is encrypted, which helps to keep others from stealing and retransmitting the signal.
There are many ways to program a key fob based on the vehicle's make and model. Some cars allow you to do this yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a replacement key fob or additional one.
When you press the button on a key fob, the microchip sends an indication to the receiver inside the car with which it is linked. The receiver compares this information with the 'allowed' signals stored in the fob and then either opens or closes the door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't permitted to operate.
Once the car is connected to a specific fob, it will only accept signals from the device. In turn, other fobs won't be able to work with the vehicle even if they look the same. This protects the integrity of the computer system in the vehicle and stops unauthorized key fobs gaining control of it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security knowledge that can only be found in the dealer's service department. Some fobs from the aftermarket, especially ones for older models with less sophisticated systems can be programmed without the need for a dealership.
