Just an update....received keys with correct code from RVlocksandmore.com None of the keys would fully insert into lock, leading me to conclude there is some internal damage to lock. So much for Plan A.
Plan B: I opened the small storage access hatch onslide out that is behind couch and directly below the designated emergency escape window. I was able to open the window and pop out the screen. I went in thru the window. The deadbolt lock would not moved. I took the back plate off and even it large pliers for leverage could not get deadbolt to move. Could not access 2 of 4 screws to further dissassemble lockset.
Plan C: I drilled out the lock cylinder and was able to release deadbolt. I ordered a complete handle and lockset assembly from Fastec and was able to get it keyed to my existing new keys. Ordered yesterday.
