   Looks neat.  But I wonder if there's a mechanical solution.  eg give the   
   customer a loop to put a padlock through to lock the lid, and hide the boot   
   button behind, such that they can't press it without undoing the   
   padlock.  Could even be something simple like a Kensington lock slot where   
   the boot button is deeply recessed in the slot - you have to stick a   
   screwdriver in the slot and can't do so if there's a lock inserted.   
      
   Of course that might cost more than your solution, so you can probably   
   ignore me :)
