How to Program a Mazda 6 Key

If you lose your key fob for your Mazda 6, you can get a replacement. Once you receive the replacement, you must program it in order to use it with your vehicle. Some car manufacturers make the process complicated so that you cannot reprogram your key fob accidentally.

1. Leave the driver's side door open and press the lock button. Immediately after you lock the door, unlock it.


2. Put the key into the car's ignition. Turn it just to the "On" setting and then turn the key to "Off" again. Do this three times in 10 seconds to enter the programming session.


3. Close the driver's side door and reopen it three times. When you finish, the door should be open and the car will automatically lock and then unlock all of the doors. If this does not happen, the programming session has not been triggered and you need to start from the first step again until you reach the point where the doors lock and unlock automatically.


4. Press the "Lock" button on the remote control then press it a second time immediately after. All of the car's doors should lock and unlock as you press the button.


5. Test the key fob by getting out of the car and pressing the buttons. All of the buttons should now work with your Mazda 6. If they do not all function properly when pressed, you must start the process from the first step. If you cannot program the key fob yourself, you should take the car and the key fob to a Mazda dealer to program it for you.
