A lot of vehicles, particularly high-end ones, require that only the dealer is allowed to make new keys.

Key Fobs
Modern key fobs provide numerous convenience and security advantages. They can be used to replace or enhance traditional keys for cars and perform more than locking doors. They can also start engines, activate alarms, and perform a variety of other functions.
The key fob communicates with receiver in the vehicle via radio signals. When you hit a button on the key fob, it sends an encoded code to the receiver, which then responds by performing the desired function. Key fobs are also a favorite among commercial building owners who can incorporate them into the larger access control system. This allows them monitor who enters and exits, and prevent fobs that were taken or lost.
Key fobs, as with any electronic device, could malfunction. They can be damaged or lose their signal if they are jostled in pockets and purses. Although they can endure a lot of abuse, they aren't indestructible. They are made from metal and plastic.
If your key fobs stop functioning, it could be time to change the battery. Make sure to use the correct battery, and refer to the owner's manual to find out how to replace it correctly. Also, make sure to follow any additional steps for recalibration or reprogramming that may apply.

Keyless Entry
Keyless entry allows you to unlock your car and begin it without having to insert physical keys. It makes use of radio signals to communicate with the car's internal system. You can also control various functions, like the climate controls or the music system.
Modern keyless entry systems utilize rolling code technology to safeguard against hacking and other security breaches. However it's important to keep in mind that even this technology has its weaknesses. Utilizing a technique known as "replay attack" thieves can make use of the transmitter of the key fob to transmit a message which is recorded by the car's receiver. Once the message is recorded by the receiver, a rogue device could send the same message again to the car's receiver and gain access to the secured property.
Depending on the vehicle's make and model, it may be possible to program new keys on your own, or you may need to have an auto locksmith do it for you. Some car manufacturers have a special onboard program, while others require that you have a sophisticated programmer attached to the OBD2 connector.
The most common method of programming new keys for cars is to put the key fob into the ignition and turn it on in a specific sequence. This puts the car into a "programming mode," and once it is activated, one or more fob buttons will be pressed to send the digital identity code to the car's computer. The computer then saves the code and then takes the car out of programming mode.
Certain manufacturers require a special advanced programmer to program key fobs and some of these are expensive and difficult to use by a typical person. It's best to leave the work to an automotive locksmith or dealer.
To begin the process of programming the new keyless entry car key, get into your car on the driver's side and close all the doors, with the exception of the driver's door. This will prevent the system from locking the doors while trying to program the key. With the ignition key and the rest of the keys you want to program in the vicinity, push and hold the button on the fob you wish to activate until the hazard lights flash twice.
