Need help! Side box door latch broke and won't open

Get a new one from the dealer. Can you get under the bunk and unscrew the nut?

 

what yr and model truck? If it's a T2000 I believe the bunk tilts up.

 

Not sure in a KW, but in a Pete you lift up the mattress and can get access to the side boxes by taking the plywood off.

 

you will need a torx head to take out the screws under the mattress

 

You have to drill the latch out

 

if your door is like the one on a t660, you can use a screwdriver to push the latch in once you gain access to the cubby from under the bunk.. depending on what part the of the latch that broke you can possible get it from a lock smith. if it's the handle you'd have to see the dealer or order online.. if it's the actual latch mechanism, then you can get that in more then a few places.. i bought one for my tool box from a local lock smith.

 

Because you will need to remove the latch to replace it I would take a small air or electric grinder and grind the heads off the rivets on the outside of the door. Hopefully you could then remove the handle and replace it.
