Deadbolt? No problem. 

Here is a quick demo of your S&D Rex or Standard Rex not being immediately available and an option to overcome residential grade hardware. It won't always be this easy but with or without a Rex, the absolute most Respectful Entry is going to be to get it to sag or drop and manipulating the mechanism as shown. It remains a homeowner fix and is a win for those we swore to protect; both their lives and property.
Our Philosophy on Respectful Entry / Through - The - Lock firefighter; right time, right place, right application. Given these circumstances, which we all are commonly presented with. Get in safely, quickly and do you job.
We always say "If you know how you will know when."
Size-up of the door, lock, frame and swing are key as well as practicing with your tools.
