How to Replace the Remote Control Battery

Model: Mazda Cx 7 MK 1 - Years 2006-2012
Part: Key

First, let's say that replacing the battery in the remote control is a very simple task that can be done with little skill in just five minutes. Before you start, make sure you have the new battery and a piece of wire. Remove the lower part on the right, then take the wire and insert it into the small slot in the centre of the remote control to lift the outer edge on the left side, then remove it. Next, take out the battery using the wire and insert the new one, keeping the remote control upright, with the writing facing down. Push it in with the wire. Now reinsert the outer edge, secure it well, and finally reinsert the first piece you removed.
