I have had my dog lock me out several times. I have the lockout issue solved. It's impossible for me to get locked out of my truck or my house. I have spare keys, appropriately placed.
I suggest you take the time to develop a strategy to fore-go this huge inconvenience. Being locked out leaves you vulnerable to more bad luck. Avoiding same is a matter of developing habits that prevent this.
It's also been my experience that it happens in groups, so it's likely to happen again soon. Take the time now to get some extra keys made,
You won't regret it.
