I have been using for about 6 months without issues now the lock won’t unlock…tried all 3 keys…luckily the bar was not on my boat at the time or I would have been in a jam! TH marine replaced the lock under warranty but this situation got me thinking about what happens if this repeats itself and I can’t unlock it when it’s on my boat? Anyone hear of problems with these locks? Maybe use a different lock? Thanks for input
