help opening toolbox door/ is it worth saving

[wreckedchevy]

another member is in need of a toolbox door so I was going to take mine off for him but unfortunately can not figure out how to get it open. the handle is broken off and I don't know if it's locked and the ignition key does not fit into the lock. anybody have any ideas on how to get it open without destroying it? also based off the pic's is this door even worth messing with looks fairly solid side note the toolbox itself looks to be in excellent condition couldn't see any cracks in it from under the truck.
