locking doors between garage bays?

I have a rental property with a 4 car garage that was probably a carriage house in the past.



I reframed and sheetrocked the walls dividing each of the bays a number of years ago, and put in automatic garage door openers, but the thing I am worried about now is if the garage door openers fail you will not be able to access the garage bays. I want to install locking doors between the bays (so tenants will not have access to each other's vehicles, but in an emergency I can enter each of them without going through the overhead doors...

The fourth garage is mine, and no intended for tenant use and has an exterior door in the back. I use it for a workshop of sorts.

The other 3 bays are used by tenants.

So my question is: What kind of locking door can I install between the bays? I don't think a typical swinging hinged door would be appropriate as it may strike one of the cars, that may be parked there. I have been looking at sliding, barn style doors but am uncertain how to install locks/security to such a thing. (I think a pocket-style might be too much work than it's worth).

Any thoughts?

How about something like this? It'll also get you in tp the garages in case of a power failure. https://www.homedepot.com/p/Prime-Li...2143/202633678

 

How big are each stall? Can't you put an ordinary door in the far corner of each stall? Would that still interfere with a parked car? Is it possible to put a door on the back of each stall?

 

I wouldn't think a 2' door would make contact with a car parked in the garage and as mentioned if it's placed near a corner there is less likelihood of making contact. .... and it's not like you'd just wildly throw open the door.

 

How about no doors? Since you might never need the doors what if you have a removable panel in the wall held in place with screws. If access is ever needed a cordless drill with the right bit could remove the panel pretty quickly. This would also save you from the possibility of losing the keys.
