ALIGNMENT OF YOUR DOOR: MORTISE LOCK, CYLINDER AND HANDLE
When you install a new cylinder in a mortise lock with handles, take care to align it along its axis. Make sure also that your lock is correctly positioned. Otherwise, the locking mechanism of the cylinder will be sticking. In fact, when your door is misaligned, you end up forcing the handle. When the handle is forced, repeated locking-unlocking may cause wear of the lock or the handle. It is very rare that this is due to a manufacturing defect in the cylinder, and often there is no need to return it to the manufacturer.
