I don't know why, but I don't feel safe having our keys downstairs (let alone in the door or next to the door) at night. So they live in our bedroom, next to our bed where they can be easily grabbed in case of emergency.
Same here. We have a locking-up ritual before going to bed.
The front door has:
- A "deadlock" (Yale type lock) with a "snib" (a little button that you can click up so that it cannot be unlocked from outside by anybody.) It uses a Yale type of key but unlike ordinary nightlatch type Yale locks, when going out you can put the key in the lock and turn it twice anticlockwise which locks the mechanism preventing anybody trying to "slip" it with a thin piece of plastic. This also locks in any person remaining in the house!
- A heavy duty mortice lock whose locking bar goes into a reinforced slot in the wall (not just the frame)
- A stout steel chain which is attached to the wall with masonry bolts and hooks into a receptacle on the door.
The back door has a mortice lock and two receessed mortice bolts operated by a key.
All of the uPVC windows have insurance-certified locks.
We feel that this is the minimum level of security that we feel comfortable with.
