Can most sliding glass doors be modified to lock from the outside?

Asked by marmoset (1311

This is I think a very typical sliding door onto a patio, in a nice contemporary style building from the 80s – I don’t know exactly what kind of sliding door because I haven’t seen it in person yet. I’m just trying to figure out whether I can assume I’ll be able to install a lock that makes it possible to use this sliding door as a normal exit/entrance – that is, lock it behind me as I go.

In response to your very generic description of the door, I would think in most cases the answer would be a very generic and qualified yes.

I have one with a key lock. I don’t know if one can be modified but I don’t see why not, especially if the frame is wide enough where making a hole in the frame won’t possibly break the glass.

Contact a locksmith, they do make kits for outside lockable sliding doors.
