Allons-y!
I use these and they work great. If you lose the "key", I believe that any magnet will open them. Or, you could just order a bunch of extra keys :lol:Have you seen the magnetic child safety locks? I've had them on the inside of cabinet doors before. They're essentially locks that attach on the inside of the cabinet, which will release their hold when you hold a magnet up to the outside of the door where they're located. I'm confident you could make those work easily if you did want to go the direction of removable panels.
These are the ones that I use (don't be fooled by the "adhesive" option-you'll want to screw them in):
