One of the most common mistakes customers make when buying a replacement tongue lock is simply by not choosing the correct measurement. If you take a little time and measure the lock correctly, you should be able to find the exact lock that you need. Another mistake that is commonly make is that customers buy a single point lock to repair a broken multipoint lock. This will not work since the 2 lock types are not the same.
A multipoint lock has an internal slide bar that transfers motion onto connected lock extensions while a single point lock does not. A single point lock does not work as a multipoint gearbox replacement. Below are some indications that your lock may have internal parts that are broken.
-
Door is stuck or jammed and cannot be opened
-
Lever handle is sagging or drooping and not returning to the horizontal rest position after the door has been opened.
-
Lock seems to be stripped when opening the door. internal gear teeth are slipping and not disengaging the lock points.
-
Lock makes a crunchy noise when opening or locking the door.
-
Unable to activate the deadbolt after lifting up on the handle.
