I keep my keys in a safe (which has a combination lock). The idea is that burglars will get in any way they can, and the first thing they will do is look for a way out. They know they may be in a hurry when they leave, so they won't want to be squeezing through small openings or breaking glass. Ideally they want you to hang the keys to your back or front door on a hook in the hall, so they can open the doors and carry out armfuls of your stuff without undue inconvenience.

I don't have fire extinguishers. I doubt their effectiveness. I do have a fire blanket for small kitchen fires, and smoke and CO detectors. I sleep in the back bedroom instead of the front, partly because that is where the emergency exit is.

I keep a hefty crow-bar under my bed, in case I have the opportunity to dig myself out after the house collapses during the night.

I have stockpiles of food and water etc for sheltering in place, but I think that's another topic.
