A key fob allows you to lock and unlock your vehicle without having to use a traditional key. It transmits radio signals to the vehicle that will then activate the onboard locking and ignition systems. The signal also allows the vehicle to read the key fob's ID, so it knows whether or not you're close enough to operate the trunk and doors.
The systems can be programmed at home, however the procedure may differ between vehicles and manufacturers. Some manufacturers use a radio frequency (RF) method for reprogramming and others require specialized equipment to access the internal memory of the system. It is important to read the instructions carefully and follow them. Incorrectly or doing it incorrectly can result in the new fob not being properly programmed.

Most vehicles erase all previously programmed fobs during the program process so it is important to have them nearby before beginning. You will then need to enter your vehicle and close the doors. Press and hold the lock key on one of your new key fobs for several seconds. You'll need to wait until your car responds to the request. This is usually done by cycling the locks or emitting the sound. Once you hear a chime, or the locks cycling, you can start programming the additional fobs.
Repeat the process for each fob. Be sure to follow the time limit specified by the vehicle. Examine the fobs after you have finished to ensure they function as intended. If the fobs do not perform as expected, you may need to repeat the procedure or seek out an expert.
