Internal Lock for Series 870 Sliding Glass Door

A handy person from Phila., PA says:
I have a Philips Products Series 870 Sliding Glass Door. The internal lock is broken. Would you have a replacement lock?

The distance between the installation screw holes is 3 5/8 inches.

We may have what you need, but I'm not familiar with that door. Could I see a few pictures of your hardware? You can upload them directly to this thread. Thank you!
A home owner from Alexandria Bay, New York says:
I purchased a home about 8 years ago, and there is a Philips 870-series sliding glass door on the front of the house that I can only unlock from the inside, because there are no keys for it. Basically, I need a new locking mechanism with a key lock, so I can start using my front door again. It's soon going to be a rental property, and I'd like my tenants to be able to use the front door without having to come in from the back door, and having to unlock it from the inside. What do I need for parts in order to help my situation? I'd be much appreciated for any feedback you can give me. Thank You!

I'd be happy to suggest a key lock for you, but we're still not sure what kind of handle this door has. Can you please take a few pictures of the handle set in question and upload them to this thread?

Thank you for these images! That's a huge help. I recommend you start by looking at our 82-226 mortise lock and seeing how well its dimensions compare to your own.
A professional from California says:
I think they are talking about needing 82-310.
The door works from inside.
They don't have keys for the cylinder that is already installed.
I would suggest taking the tab off the old cylinder and swapping it with the new one.
It's easier than cutting the new one.
