Patio door bolts sticking...
When I turn the handle to open the door a bolt, inside the door, to secure it at the top drops and one at the bottom of the door lifts. Sometimes the one at the top doesn't drop and the door won't open. Any suggestions?

For more on marking an answer as the "Best Answer", please visit our FAQ.these locking systems sometimes have a method where the locking bar at the top and bottom are on a small plate about 2mm thick by about 15mm wide and 50mm long with teeth along the long edges, these teeth fit into an opposing bar that are connected to the handle system, this is so they can be slackened off and adjusted by sliding the bolt up and down the bar.....if this mechanism works loose then the two parts will separate and not function......when the door is open, you should see a set off screws along the locking system and i would think the ones at the top have worked loose.....its just a case off tightening all the screws and lubricating the mechanism........when these doors are made they are just long lengths of profile, cut, mitred, metal strengtheners added and welded together to form the door at the correct size, then all the hardware is added afterwards like hinges, locking systems etc......you never need to replace a door because of a failed lock or part of a lock
