Now, let’s delve into the step-by-step process of installing each type of lock mentioned above.
Deadbolt Installation
Step 1: First, measure the distance from the edge of the door to the hole where you’ll install the deadbolt. This measurement, known as the “backset,” is typically either 2 3/8 inches or 2 3/4 inches.
Step 2: Place the deadbolt template on the door, aligning the template’s backset mark with the edge of the door. Tape the template in place.
Step 3: Use a hole saw to drill a hole through the door at the location marked on the template. Make sure to stop drilling when the pilot bit emerges from the other side of the door, then complete the hole from the other side.
Step 4: Install the bolt and thumb turn assembly, ensuring it is correctly oriented with the “up” mark facing up.
Step 5: Align the outside part of the deadbolt lock on the door by threading the long screws through the inner plate, and securing the lock.
Mortise Lock Installation
Mortise locks require a pocket—the mortise—to be cut into the door where the lock is to be fitted. Though slightly more complex, the additional work pays off in heightened security.
Step 1: Mark the height of the lock, and then use a mortising template to outline the pocket area.
Step 2: Use a mortise chisel to cut out the pocket. It’s essential to keep the chisel straight while making these cuts.
Step 3: Drill a hole through the door for the spindle and another hole for the keyhole.
Step 4: Install the lock body into the pocket, ensuring that the keyhole is correctly oriented.
Step 5: Secure the lock with screws and then install the spindle, followed by the doorknob.
Keyless Entry System & Smart Lock Installation
Keyless entry systems and smart locks are becoming increasingly popular due to their enhanced security features and convenience. Their installation typically involves:
Step 1: Removing the existing deadbolt.
Step 2: Installing the new deadbolt supplied with the system.
Step 3: Attach the front face of the lock, thread the wires under the latch, and connect them to the appropriate terminals.
Step 4: Affix the rear mounting plate and install the batteries.
Step 5: Testing the lock and programming as per the manufacturer’s instructions.
