To purchase a new locking mechanism, you need to know who manufactured the door. They are not universal.
The door is currently operating like it was purchased without a locking mechanism.
Depending on the year of manufacture... the glass is etched with either the Cardinal or Guardian label if manufactured in the US or some times Canada.
But knowing if it is wood or vinyl helps me know whom may have manufactured the unit.
If the unit is newer, then after they unlock and open the patio door from the inside they can look up... manufacturers place labels on the head jamb with information that they can use to get the correct replacement parts for a unit.
