The primary tool used for installing locks is a drill. A drill is essential because it allows locksmiths to create holes in various materials, such as wood or metal, where the lock will be installed. Specifically, drilling is often necessary for making the cylindrical hole for the lock body and the smaller holes for screws to secure the lock in place.

Using the drill effectively can ensure precise placement and the proper size of holes, which is crucial in maintaining the functionality and security of the lock. While other tools such as wrenches and screwdrivers have their roles in the installation process—wrenches for tightening or loosening hardware and screwdrivers for driving screws—they do not perform the initial function of creating openings for the lock unit itself, which is a critical step in lock installation. A chisel might be used in certain situations, but it is generally more for adjustments or modifications to existing woodwork rather than for the initial installation of the lock.
