Glass Door Wont Open

If the sliding door is still sticky after the tracks have been cleaned use powdered graphite or silicone lubricant to ease things along.
Glass door wont open. When the door knob is locked the handle will not turn which keeps the latch from retracting. Most sliding doors have a mechanism called an adjusting screw located at the bottom of the door ends. Turning this screw raises or lowers the roller. A door knob or door handle uses a spring loaded latch.
Getting the door to open. Slide the key in the lock and tap lightly on the key to lubricate the inside of the lock. In the resting state of the lock the spring is extended. Don t use a wet.
Take the door off the hinges. When there s dirt in the door track it not only makes it hard to open and close the door it may cause serious damage if the door jumps the track when it hits an obstruction. The turning of the handle retracts the latch by pulling on the spring and compressing it. If the door becomes even harder to open turn the screw in the opposite direction.
Give the screw a clockwise turn and test to see whether the door slides easier. Examine the door closely. This will actually help to move around the lubricant into the harder to reach middle area where the door is constantly sliding and experiencing the friction that makes it stick. If the set screw on the handle is stripped and difficult to tighten replace it with a new one.
If the door does not allow the lock to be jimmied open it may be necessary to remove the door from its hinges. If this is the problem clean the paint off. Paint on the edge of the door sometimes prevents the barrel from retracting. Insert a long sturdy item with a flat tip preferably a flat head screwdriver if available between the top rung of the door s top hinge and the head of the bolt securing the door to the hinge.
Move the door back and forth like you did in step 1 to help the door glide over the oiled areas. Flip the key and open the door. Spray the door key with a graphite based lubricant. This is usually easier to do from the inside especially if you ve got.
