Besides, around here, burglars usually just kick in the door instead of fooling with the locks anyway
Agreed, although in our case, it is going to be a lot harder going than they might realize. 1 3/4" solid oak plus two reinforced deadbolts plus the latch (probably hard to hold the latch while they kick).
A door lock - any door lock - only provides $25-100 of security, or at most 30 seconds of time until someone gains entry.
30 seconds could be a REAL long time when someone is trying to break into your home with the aim of doing you harm.
