Does it matter that the key was stuck outside the door all night last night?

I don't think so. Yes! No one will care so much about your lock! You mean you are afraid that others will take your keys and make copies at night! Then I'll send it back to you and plug it in! Rest assured! It's okay! How many thieves stare at other people's locks every day! Tell you what! You are very lucky! No one else found out! Otherwise, I will steal from you!
