need a new key lock

Question

I need a new key lock for our sliding glass door to make it a safe entrance/exit, since we don't have the key for the current assembly. But I'm not sure which key lock to order from all your choices. I'm attaching photos of the lock we have. Please let me know if you can determine what I need. Thank you!

Your sliding door looks like it will take our 82-302 key cylinder. However take note, patio glass door locks are not high security. You really cannot beat a "Charlie Bar" or a 2 X 4 piece of wood in the track. You may want to talk to a locksmith about a high security option for your sliding door. We also have a few secondary patio glass door locks in our sliding door accessories catalog section.
