So our garage door no longer locks and I'm a bit concerned for the automotive beauty parked inside, not least because earlier today the door magically opened.
How can we get it to lock again? The garage door is a one piece sheet metal contraption that is recessed from the front and tilts/slides up to the roof. The reason it doesn't lock any more is because one of the inner lock arms (that should slide in and out) doesn't slide so much and also the lock is a bit dodgy.
I'm open to any solutions, however I should point out that it would more than likely be me and my dad fitting this so please, no pneumatics or other difficult stuff
