This Handle’s Loose
If you’re going to make a lock that will carry on working though ten years and ten thousand operations, there has to be play in the handle and the mechanism. So the excellent Yale #1 and Yale #2 have “loose” handles — on day one.
So does the Unican mechanical digital lock.
One thing you do have to watch out for on a Yale #1 or Yale #2 is that the securing screws — the little fellers above and below where the bolt comes out — do work loose. So if the whole lock is wobbly, tighten up those screws — just until they pinch — don’t over-tighten.
