It will depend on who made the latch
Tri-Mark if it's the kind of latch that latches on teh bottom
First problem is finding a bolt.. IF, and only IF they are identical to the ones on my Damon... Seneca Engineering in Seneca SC has the specs and can cut you a new one.. IF not take the old bolt to someone like them (Metal smith)
Collect any parts that fell out If basement is latched see below
Remove 4 screws, from backing plate remove plate and set aside
Remove assembly lay Outside face down and take a photo with your digital camera
Remove one screw and left off the transfer lever and washer NOTE the order they go back on.. Slide rest of bolt down and out. Take bolt peices to metal smith (They do not sell the part)
YOu need to put the spring in the cut out part of the bolt when reassembling.
IF the door is latched.
A long thing tool (Screwdriver) if you can slide under you might be able to push the bolt up with the tool and open the door.
The design of the Tri-Mark lock.. all but guarantees they will break.
Home was where I park it. but alas the.
