Why We Examine Your Door and Frame Before Changing a Lock
Before any new lock hardware is installed, our technicians conduct a thorough assessment of your door's alignment, the strike plate, and the condition of the door jamb. Many seemingly "failed" locks are actually symptoms of a door that has settled, hinges that are loose, or a strike plate that has drifted out of proper position over time. Ignoring these underlying issues means even a robust new Grade 1 deadbolt will not perform optimally or resist forced entry as intended.
This crucial first step ensures that any new lock, whether a standard knob or a high-security deadbolt, will operate smoothly and provide its full intended security. We check for worn screws, hollow jambs, and proper door gap, reinforcing weak points with longer fasteners or specialized hardware before proceeding. This methodical approach guarantees your new lock's longevity and security.
Step-by-Step Installation of Your New Deadbolts, Knobs, and Levers
Once the door frame and alignment are confirmed, our locksmith carefully removes your old lock hardware. We then prepare the door for the new components, often involving minor adjustments to the bore hole or the mortise pocket to ensure a perfect fit for modern security products. Hardware is matched to your preferred finish and, when you want it, keyed to your existing key.
You can request that your new locks be keyed alike to an existing key you already use, reducing the number of keys on your keyring. This process involves precise re-pinning of the new cylinders to match your existing key's bitting code. We test the operation thoroughly, ensuring smooth engagement of the bolt and latch, correct key rotation, and reliable function from both sides of the door.
Reinforcing Your Entry Points for Added Security
A significant weakness in many residential door installations is the strike plate and the integrity of the door jamb. Standard builder-grade strike plates are often thin and secured with short screws into softwood. For enhanced security, we can install reinforced strike plates, often made of heavy-gauge steel, secured with three-inch or longer screws that penetrate directly into the structural stud behind the door frame.
This reinforcement drastically increases the door's resistance to kick-ins, a common method of forced entry. Paired with a robust Grade 1 or Grade 2 commercial-rated deadbolt, this approach creates a significantly stronger barrier against unauthorized access. This attention to structural detail goes beyond simply swapping out a lock, providing a more comprehensive security upgrade for your Gaithersburg home.
