What Happens During a Professional Lock Installation?

Behind the Scenes of a Lock Installation

When a Provo Locksmith UT technician arrives at your door, what exactly happens? Here's a step-by-step look at what a professional lock installation involves.

Step 1: Assessment

The locksmith first examines the door and existing hardware. Key factors include:

• Door material (wood, steel, fiberglass)
• Door thickness
• Backset measurement (distance from door edge to center of the knob hole)
• Existing prep holes and bore size
• Door frame condition and strike plate setup

Step 2: Hardware Selection

If the customer hasn't already chosen their hardware, the locksmith recommends appropriate options based on the door type, security requirements, and budget. For most exterior doors, a Grade 1 deadbolt is recommended.

Step 3: Door Preparation

If the new lock requires different bore sizes or locations, the locksmith uses a hole saw and door template to create the correctly sized and positioned holes. On a door that already has proper prep, this step may be skipped.

Step 4: Installing the Lock Body

The lock assembly is inserted into the bore hole, and the mounting bolts are tightened to the specified torque. Over-tightening can warp the lock; under-tightening allows movement that compromises security.

Step 5: Installing the Strike Plate

The strike plate is mortised into the door frame and secured with long screws (ideally 3 inches) that reach into the wall stud. This is the most critical security step — a weak strike plate is the most common cause of door kick-ins.

Step 6: Key Cutting

If a new key is needed, it's cut using precision equipment to match the lock's keyway and pin configuration.

Step 7: Testing

The finished installation is thoroughly tested — locking and unlocking from both sides, checking the deadbolt throw, and verifying smooth operation. Any issues are corrected before the technician leaves.
