A window lock that no longer lines up can indicate more than worn locking hardware. The sash position, tracks or surrounding frame may affect how the parts meet. Forcing the lock does not identify the cause. An inspection should establish whether the problem is in the lock itself or in the window's overall alignment.
Describe whether the window also sticks, feels uneven or has become harder to close. Those symptoms can help connect the locking complaint with the way the sash moves. Mention recent work or previous adjustments if known. Photos showing the whole unit and the visible lock area give the technician a better starting point than a part name alone.
A replacement lock should be compatible with the existing window. Similar appearance does not guarantee the same fit or operation. The service proposal should identify whether the job includes alignment or other hardware work alongside the lock. Ask for the finished window's closing and locking behavior to be reviewed as part of the handover.
