Key Programmers
Modern vehicles require a key-programming method to start the vehicle's system and start the car. In many cases the key needs to be set up by the dealer or auto locksmith.

The reason is because the new key has not been programmed into the vehicle's system, and this could be very costly. This is why it's a good idea to have two keys working for a modern automobile and to have the replacement key programmed when necessary.
A keyprogrammer can recode the transponder chip on an entirely new mechanical key or key fob. It is also able to copy the data from an existing key and allow duplicate keys to be created. These devices are handheld units that connect to the 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.

Transponder Chips
If your car was manufactured in the last 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 vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by the antenna that is attached to the ignition barrel of your car. The computer system of the vehicle will then confirm that the key's transponder chip is the correct one for your car.
This prevents the vehicle from being started through hot-wiring, or by manipulating. The chip inside the key ensures that the owner is the person who owns the vehicle. This can help to reduce the possibility of theft from your vehicle.
Regular transponder keys are shaped like regular keys, but with a plastic top. The chip is housed in the plastic portion of the key and there are a few different kinds of cuts available on these keys: a regular cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.
The circuit in the induction coil emits signals when the transponder is put into the ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer on the car recognizes this signal as being the right one, it will disable the vehicle's immobilizer and allow the engine to begin.
If the vehicle does not recognize the transponder signal as the correct one, it will stop the engine from starting and will notify you by flashing its lights and sounding an alarm. This is designed to deter people from trying to tamper with the vehicle, however it's not a 100% security measure. A skilled and determined thief could still be able to bypass this system by employing a device designed to intercept the signal.
You can see that the transponder is an excellent option. All car owners should take this into consideration in order 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 a car in a parking space keys of today can also activate the heated steering wheel or roll down all of the windows with a single press. These extra features can make it difficult to find your car keys.
Key fobs communicate with one other and the car using radio frequencies that are transmitted by an antenna in the center of the key. This signal is encrypted to stop others from stealing or stealing the signal.
There are a few different ways to program a key fob depending on the make and model. You may be able to do it yourself, but most newer vehicles require a dealer or professional locksmith to program a replacement or an additional fob.
When you press the button on a key fob the microchip sends an indication to the receiver in the car with which it is paired. The receiver then compares the data with the 'allowed signals' stored in the key fob and then opens or locks the car door. If the information does not match the signals, the car will not be allowed to drive.
Once programming car key has been associated with a particular fob, it will only accept signals from that device. As a result, other fobs will not work with the vehicle even though they appear similar. This helps to protect the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. It is because the only place that has the expertise to prepare the replacement fob is the service department of the dealer. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems -- can be programmed by consumers without the need for dealers.
