You don't need to pry the whole keypad from the wall. Just carefully pry off the outer section. The circuit board can then be removed for battery replacement - a CR2032 is required. As someone else mentioned, check that the battery is firmly held in its retainer. You may need to bend some of the retainer tabs to ensure good contact. My keypad stopped working a while back because water had gotten into it after some heavy rain. I ended up applying some exterior tape to the joint between the front of the keypad and the keypad body to seal it. This has worked well, with the keypad staying functional even after heavy rain.
Thanks, I assumed that they were all the same. The screwed keypad sounds better. Mine splits, but also lets water in, which if left unattended kills the battery. I've just taken mine off again as snow melt was dripping down from the end of the awning and getting. I needed a new battery after cleaning it out. I'm going to have to make a shroud for it, or maybe get Southco to send me one of better design.On ours, the keypad is firmly held together by 8 very small screws and must be removed from the trailer to get apart. The 8 screws must be removed with a small jewelers screwdriver to get to the battery. I guess Southco used different models depending on the manufacturing date (our trailer was built in Aug 2010).
