SWISCO - The Replacement Hardware Authority

What can I install to lock my Andersen door?

A landlord says:
I have the Andersen Sliding Door Lock N9-00191-00001
and i want to be able to lock it from the outside so what lock do you think i should buy that will fit in it.And we don't want to drill into it since the glass goes into the door, thank you.

I'm not sure what you need, however if your door didn't originally have a key lock then you will have to drill. Andersen does not predrill holes for locks. Can I see a few pictures of the handle and inside locking lever you have now? That will help us find what you need. Thanks!

Thank you! No, I don't think you'll get away without drilling. Either way, see our 82-310 key lock. I think this should work with your inside mortise lock.
