I have one of these on my boat and it doesn't work now when I put the key to lock and unlock. Are these easy to install and can you send directions? Thanks.

Rated 5 out of 5 by from Perfect for new construction, or security on any sliding door This lock when properly installed not only locks a sliding door, but also prevents it from being lifted out of the track. THe device is perfect for new construction on a second floor where a deck is planned for later construction. Under those circumstances code requires a fence or guard be installed across the door opening. THis pf course damages the door frame and siding such that a repair is required when the deck is installed at a later time. Most inspectors will accept this lock as sufficient to meet code as it prevents the door from opening without the key, and it mounts at the top of the door out of reach of children.

Rated 3 out of 5 by from Description/Instructions could have been more detailed Description/Instructions could have been more detailed. It should have stated that you needed to drill holes in the door and the frame. Overall it was a good product.

Rated 1 out of 5 by from Not working as it should I bought this lock because of the good reviews. The lock is installed on the bottom of the patio door, when I pull the lock up to slide the door open, it won't stay up at all. My previous lock worked fine until it finally wore out after many years. Disappointed. Plus I had a professional install the lock.

Rated 5 out of 5 by from Best security for sliding doors If you want your sliding door not to be opened by a thief, this is a must. Locks the door well and when you will be gone for a week vacation, use the key so nothing goes in or out of the door. Easy to install.
