Chamberlain Garage Remotes

So the keypad in my garage is playing up.

I got my Beth to change the PIN number which seems to have fixed the problem. To me this sounds like an issue with one of keys being broken. I was thinking we could use the same logic as with Bulls and Cows to deduce if there is a key broken.

So fixing the problem. We can get another remote. Looks like a generic version of the remote exists:

We can also buy a new control pad.
