Ok, on to your question. By letting it bother you you are giveing her the power. Just freeze her out in that situation. Display that it doesnt bother you and ask your friend for the lock. She will be dissapointed that you didnt jump through her hoops, and the end up giving you your lock back. At that point you can kiss her.
By kissing her while she is doing something that you dissaprove of is giving her the power and letting her its ok to treat you like that. Relationships are often times like puppy training. Would you pet your puppy and tell them good dog after they shit on your floor? No, because its unnacceptable behavior. Do the same with your chick.
Hope this helps.
