Well I have solutions for people who experience malfunctionning keys on their Gyration remote (or other remotes for that matter).
First to open the remote you need to unscrew the small screw under the batteries. Then with a small screwdriver or plastic tool, open up the remote from the middle of the long side, and work your way around.
Now for the malfunctionning key, the problem is most likely because the conductive carbon layer that coats the black silicon keys has worn out. You cannot see it as it is black on black, but the lack of conductivity is what causes the keys to badly work, or stop working all together.
There are two ways to fix the problem.
1) The best long term way is to use a Rubber Keypad Repair kit to recoat the keys. See link here:

Important to note, the product requires mixing two components, but you dont need to mix all of it at once. It does require at least one day to dry (preferably 3).
2) For a single or couple of buttons, you can also do a quick instant fix using aluminium foil and double sided tape. See link here:

Once the conductivity is restored, the keys work like new...
