How are deadbolt locks mounted?

• A. In a precut hole in the door
• B. On the surface of the door
• C. In the frame
• D. Inside the wall

Answer: (A)

Deadbolt locks are installed by creating a precut cavity in the door to hold the lock body and a separate edge bore for the bolt to extend. The lock mechanism sits inside the door, while the bolt projects through the edge of the door into a strike plate set in the door frame. This setup ensures the bolt can securely engage the frame when locked. Mounting the lock on the surface or elsewhere wouldn’t allow the bolt to operate properly, so the standard method is to place the lock inside a precut hole in the door.
