I need a replacement lock for Truth Entry Gard sliding door that leads to my deck 1984. Two pictures will follow. If you can help me I will order 3 to have 2 extras.

Unfortunately, this handle set is no longer available. If the mortise lock it interacts with is something like our 82-218 or 82-239 , you might be able to use a handle set like our 82-030 as a replacement. 

Although, I can't guarantee this would work; you will have to drill new holes to try it. 

If you're unsure, send us photos of the mortise lock and confirm your measurements so that we can take a further look.

A home owner from 22 Coss Lane Montague,NJ says:
I don't need to replace the handle just the lock.The other lock broke in 2021 & my locksmith replaced just the lock. He couldn't find me another lock this time. I don"t know what other photos I can send of the broken lock. Any photos I send must come as a text to phone number 888-991-1929 as I have done in the past. I don't know how to send photos on my lap top.

Since it appears the part that is broken is the lock, that locks the door, it is likely that you will need to replace the handle set. Unfortunately, we cannot offer a replacement for the lock. It is an extremely old handle set that isn't made anymore.

Please text your photos to that phone number and include your discussion number so that our customer service agents can make sure they are forwarded to me.
