We need a practical, reliable and robust locking mechanism that is not overly complicated for this application.

We have powerful air pistons.  We could rig one up with some small solenoid valves instead of using a big solenoid as the locking mechanism.  The air piston could actuate a mechanism that interfaces with both a point above head level, and/or a hole drilled into the floor.
