Sliding glass door exterior key lock

A quick learner from Westport, CT says:


I have an older Anderson sliding glass door. The attached photo of the series number isn't very legible but it's a 1991 series. Looking at the door from the exterior, it opens to the left.

I want to add a keyed lock to the exterior handle. What is the appropriate part number for the exterior lock? I assume that I will need an exterior handle with punch-outs for the lock. Please advise. This is not my area of expertise so I look to you to make sure that I have all parts necessary.

Your assistance will be greatly appreciated.

Take a look at either our 82-316 left-hand lock or 82-317 right-hand lock. Both of these are meant for Andersen door locks like yours. Handing is determined from the outside looking in. Thanks for posting!
