Mazda vehicles of all different types are equipped with keyless entry technologies. Cars such as the Mazda 6 use this capability to control a number of different security and convenience features. You can program your own Mazda system in just seconds using a short programming sequence. With this process, you can have as many as four different remotes ready to use right away.
Enter your car and leave the driver's side door open.
Lock and unlock the door with the button on the driver's side door. Insert your key into the ignition and turn it to "On" and "Off" three times in quick succession.
Open and close your driver's door three times, then open it once more.
Wait for the door locks to automatically cycle and press any button on the remote two times. The doors will lock and unlock again. Remove the key from the ignition to end the programming process.
