Searching for atrium door lockset with 45/92 mortis lock

Purchased an Atrium door from Home Depot in 2005. Deadbolt is broken and cannot open door now. My lock looks similar to your 82-400, however the overall measurements are different. The outside and inside covers are 8 1/2" X 1", and the cutout for lock is very close to those same dimensions. Believe the 8 1/4" would not cover hole. The lockset on mine is stamped as a "45/92", and is very similar to the Hoppe 45/92 mortise lock, with the exception of the deadbolt key and turn nob. Any help would be appreciated.
