Questions

Euro profile cylinders protrude on both sides of the door and are the standard in European architecture. If your door was supplied by HELT or is a European-style entrance system, it almost certainly uses a Euro profile cylinder. If you have a thumb-turn on the interior and a keyhole only on the exterior, you have a standard deadbolt.
