Most US locks are Schlage or kwikset (personal experience, but backed by [1]) - both require only a single turn and are direct locking - turn to the left locks, to the right unlocks, if it's already in the position you're trying to set it will only do a quarter turn, and the key must be in the upright position to remove. I would be very surprised to encounter a European style lock, but it may be that some regions prefer them (I'm in the northwest, having previously lived in the east coast metroplex)

- alistairSH 8y agoMy experience is the same - door deadbolts are as you describe. Locking knobs are a bit different, in that some have a deadbolt function, but most just lock-up the knob itself (to prevent turning). Regardless, these aren't often used as the primary means of securing an exterior door - there's almost always a deadbolt.
