I planned on using it to control a garage door, preventing my children from opening the garage door in the chill of winter. I couldn't get either remote to control the power unit. I took the remotes apart, removed the small plastic shielding strip (intended to prevent battery drain) put them back together, and neither worked. I flipped the batteries, tried everything. I could manually engage the power unit, so it was functional, but the remotes wouldn't control it. The instructions say to pull out the sliding battery piece. As it turns out, that's just to remove the shielding. The sliding tray has to be reinserted flush. Then the remotes work. Both remotes come with 2032 batteries. I've tested both, both work as intended. So, it's good. A little frustrating for me, but I'm not the sharpest knife in the drawer.
