Keep a key to that lock handy in a hidden place. The deadbolt takes care of the "problem" of a key outside.
Don't be like me. Nowadays, the the literal first thing I do is put the green key thingie on my wrist no matter how sweat soaked my work clothes are. Back in March I'd gotten out of the shower on a rainy/windy day and gone outside in an old bathrobe with an umbrella for a smoke. The old lock locked me out. So, there I was, walking the several hundred yards in bathrobe (nothing else on) and umbrella to the RV park office to borrow tools. And, yes, after several attempts at other ways, I had to remove a jalousie window and crawl in -- a$$ flapping in wind -- from a plastic chair. And a cinder block. Good thing I don't embarrass too easily, huh?
In fact, place a few of those keys around, willya?
