Locks which have the keyhole in the knob are not reliable; they can be easily forced from the outside.
	Install 1-inch deadbolt locks on all exterior doors. Caution must be used when installing double-cylinder locks on emergency exits.
Padlocks should be of good quality with heel-and-toe locking.
Key control is important. If keys are lost, or new owners or tenants have moved in, locks should be changed. Don't hide keys outside
