I bought new storage locks from either Camping World or RV Plus (can't remember) for my older 2010 SAB Cougar that I traded in for my new Cedar Creek 5er. They sell them in different lengths for the storage doors. The reason I did this is that only I have the key for them and not everyone else. I bought a set of them for three doors and they are all keyed a like. The standard 751 key will not work on them. See this link.

I went to rvlocksandmore .com when I replaced my entrance door locks and got new compartment locks that They keyed the same as the entrance doors. As others have mentioned the compartment keys for all rv's are the same key.
Think about things before you do them make life easier not harder.
