The owner's manual should contain specific instructions for the particular model and type of key you want to program. Some models have extra security features that need to be enabled.

Key Fobs
Modern-day key fobs offer a host of advantages in terms of security and convenience. They can be used to replace or augment traditional keys for cars and be used to control more than only locking doors. They can start the engine, activate the alarm and perform other functions.
The key fob communicates with the receiver in the vehicle via radio signals. When you press the button on the keyfob, it sends the code to the receiver, which performs the desired function. Commercial building owners also use key fobs to connect them to a larger system of access control. This allows them to monitor who enters and leaves and can prevent fobs from being stolen or lost.
Like any other electronic device, key fobs can fail periodically. They can be damaged or lose their signal when they are jostled in pockets and purses. And although they are built to endure a lot, they are not indestructible; after all, they're nothing more than metal and plastic.
If your key fob stops working, it may be time to replace the battery. Make sure you use the correct battery and refer to the owner's manual to find out how to replace it properly. Make sure you follow all additional steps required for reprogramming and recalibration.
Wear and tear is another common reason for failing fobs. Since they are frequently dropped, pushed into objects, and jostled about in purses and pockets they may wear down or even cracked. Oftentimes an easy and affordable fix is all that is required to get your key fobs back functioning.

Keyless Entry
Keyless entry lets you unlock your car and start it without needing to insert physical key. It uses a wireless signal to communicate with the car's internal system, and it can also allow you to control various features in the vehicle including climate controls or music systems.
Modern keyless entry systems utilize rolling code technology to protect against security breaches. However it's important to remember that even this technology has its weaknesses. By employing a technique dubbed "replay attack," a thief can use the key fob's transmitter to transmit a message that is recorded by the car's receiver. Once this message is recorded, a rogue device can send the same message again to the vehicle's receiver and gain access to the protected property.
Depending on the vehicle's model and make, it may be possible to program new keys on your own or you might need to hire an automotive locksmith do it for you. Certain car manufacturers have a special onboard program, while others require that you have an advanced programmer connected to the OBD2 connector.
The most commonly used method to program 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 in a "programming mode," and once it is, one or more fob buttons are pressed to transmit the digital identification code to the car's computer. The computer stores the code and takes the car from programming mode.
Some manufacturers require an advanced computer to program key fobs and some are expensive and difficult to use by a typical person. It is recommended to delegate the job to an automotive locksmith or dealer.
To start programming for a car with keyless entry start by entering your car from the driver's seat. Then close all the doors, with the exception of the driver's. This will stop the system from locking the doors while trying to set up the key. Press and hold the button on the fob you wish to activate while the ignition is on and the other keys you wish to be programmed are close by. The hazard light will flash twice.
