The Initial Assessment and Door Preparation

Before any new lock is installed, a thorough assessment of your door and frame is essential. Many issues attributed to "failed" locks are actually due to a misaligned door, a worn strike plate, or an inadequate jamb. We examine the door's alignment, the existing bore holes, and the strength of the frame. If the door sags, the hinges may need tightening or shimming to ensure the lock's bolt extends properly into the strike. A Grade 1 deadbolt provides excellent security, but its effectiveness is severely limited if installed into a soft or hollow jamb. We ensure any new hardware is supported by a robust frame, sometimes reinforcing the strike plate with longer screws that reach into the stud. This foundational work helps ensure your new deadbolt, knob, or lever functions correctly and offers its intended security for years.

Matching Your New Hardware and Keying Preferences

Once the door preparation is complete, the next step involves selecting and fitting the new lock hardware. We offer a range of options, including Grade 1 and Grade 2 residential deadbolts, knob sets, and lever handles. You can choose finishes that match your home's existing aesthetic. The installation process involves precise measurements and drilling to ensure the new lock fits snugly and operates smoothly. A common request is to have your new locks "keyed alike" to your existing house key. This service streamlines your access, allowing a single key to open multiple doors. We perform this on-site, using specialized pinning kits to reconfigure the cylinder tumblers to your existing key's bitting. This process ensures convenience without compromising the security of your new lock.

Final Testing and Ensuring Optimal Operation

The installation is not complete until the new lock has been thoroughly tested. We check the full throw of the deadbolt and the smooth retraction of the latch. The key should turn effortlessly from both the inside and outside, without sticking or requiring excessive force. We also ensure the door closes and latches correctly without binding against the frame. This final step is crucial for long-term reliability. A properly installed lock should operate with minimal effort, providing confidence in its security. The entire process, from initial assessment to final testing, typically allows us to complete residential lock change and replacement services on the same day in Mount Rainier.

When we moved into our new place, we called Chaim to rekey the locks. He was quick, professional, and very helpful. He also adjusted the doors, and they now close and lock more smoothly. Highly recommend using Q 24/7.

Hay was extremely professional and very courteous. He did an outstanding job replacing 2 locks and re-keying one lock for me. Hay took the time to explain what needed to be done and why. I would absolutely use this company again. And their prices were very reasonable.
