30 P/U - locking passenger handle removal - it's locked!

[steve hackel]

Helping my friend Nick disassembl his cab and doors; the locking RH door handle is locked and he has no keys, and we can't figure out how to remove it for further door disassembly.
Trying to strip down the doors : regulators, glass and channels, Door handles and finally the undercoating inside the skins - but we're stuck at this point and need some help. Thanks
