Was going to say you'll have to strip door trim and see what's happening , then found this ,
If a door lock jams locked, try this: Remove the drivers door lock button ( it pushes upwards), remove the screws from the door handle, then gently prise the top of the door inside panel away from the door, just enough to get your hand in and fiddle about with the connection that operates the door handle, push it up, pull it down, several times, and the door should open. Then completely remove the door panel and spray a moisture dispersant such as WD 40 onto all the moving parts.
or this ,

To reiterate Dynamic Dave is correct
I have done this to open my Omega whenever a faulty alternator drained battery
Quoting from handbook - To unlock -
Turn key in driver's door lock towards front of vehicle turning it beyond its resistance point until it will not move any further ( hence reasonable force ). Turn key back to vertical position and remove; raise door handle. The lock button remains in depressed position but door will open
Worth a try , might work .
