Hi Spuder, welcome to Lockpicking!
First off, I love the subject title, it's precise, there is no doubt of what you are asking!
So let me get straight to the answer:

Now don't we all? What a fantastic world we live in!

Is it only on the inside? How do lock lock the door from the outside then? Do you by any chance have a backdoor?
spuder wrote:We some how locked it from the inside or we just can't find the key.
Yes, you've definitely locked the door from the inside and then you went out the backdoor!
spuder wrote:We just can't find the key.
It's in the keyway on the inside, remember, you locked it and went out the backdoor!

How do you safely do what?
Go around the house, open the back door, (the key is under mat), you will now have access to the deadbolt, that is located on the inside, the key is in the keyway!
