Had to make a 10 day trip back to Idaho to tie up some loose ends. Before leaving I put all my extra house keys, property keys, important documents, etc..., into my safe. Never had even a hint of a problem with the manual combination lock.
Got home last night and tried to open the safe this morning. Went thru the normal unlocking procedure but the lock didn't open. Tried again, same results. Double-checked the combo...correct. Spun it slowly several times to "clear" it. Nothing. It was acting as though I was entering the wrong combo. It finally opened on about the 5th or 6th try. I didn't really do anything special other than a little slower and stop precisely on the numbers...but I'd really done that a couple of times.
Any idea what might be wrong? I bought it used from a forum member many years ago and it's always been trouble free.
Do lock mechanisms need to be cleaned or do the need some special service? If so I've completely neglected to do that. I'm afraid to lock it now.
It's an American Security BF6030 made in 2007...I don't see a brand name on the lock.
