No need to remove the latch. Just drive the motorhome to a locksmith. He has master keys to remove the tumblers from the front.
A locksmith can do miracles for you in changing all your compartment keys and such, key'd alike to greatly reduce key confusion.
I had my locksmith key-alike the deadbolt and regular lock in the entry door, using a rectangular blank. All other locks have a different keyset, so they require a different key. All of that type are key'd alike with a round blank for easy ID. So I went from 5 keys, to 3 keys. You can imagine, this helps immensely in the dark, feeling for the rectangular key, teeth down to get inside.
1) Ford chassis key
2) rectangular entry door key (for both locks)
3) round key for all compartments and spare tire.
