problem. But as far as I know, it is not one key for two lock, it is one key
for one lock and the other lock can be opened on both side without key.
The lock requires key have a tongue of a bar. So if the door is open with
tongue stick out, it can't be slam shut (no spring). The other lock is a
wedge like structure with spring. It always stick out and the slope of the
wedge facing the door frame. It can be slam shut.
