Have you lost the keys to everything? Just the storage compartments? shower hatch? or walk-in door? Are the spares in your Aframe?
The keys/locks on the storage compartments are probably the same as just about any other camper on the dealer lot (or in the campground). The door key should be a little more "unique" to your rig.
Our storage compartment key is CH751, probably the same as thousands of other campers.
The door keys may have
a number on the inside portion of the lock-set to get a new key made. I'm not sure about that though, my Aframe is closed up right now.
Unless it is popped up and the door is locked, you are not really locked out. If it is folded down and you have padlocked your camper top closed, use a bolt cutter to cut the padlock, pop the top and the upper half of the door will open. Then reach in and unlock the lower half door.
Our 2012 A126 came with 2 sets of keys. We keep the "spare" set in the tow vehicle glove compartment.
hth, I'm not sure exactly what you need to know.
