What Happens After Your Locks Are Changed?
When Q 24/7 Lock Service replaces your residential locks, the first step is always proper installation. We ensure your new deadbolts, knob sets, or lever handles operate smoothly without friction or binding. Before we leave, we will cut and verify any new keys, ensuring they turn freely and retract the bolt completely, preventing common issues like a stuck key or a deadbolt that only partially engages.
We provide you with a fresh set of keys for your newly installed hardware. If you requested keying to an existing key, we confirm that all specified locks now operate with that single key. Our work is covered, giving you confidence in the security of your Ferndale home. We focus on durable, reliable performance from the moment we finish the job.
Addressing the Root Cause of Lock Failure
Many perceived "failed" locks are actually symptoms of a misaligned door or a worn-out strike plate, rather than internal mechanism issues. Before installing new hardware like a Grade 1 deadbolt or a new mortise cylinder, our technicians first inspect the door's alignment, hinge integrity, and the door frame. This includes checking the gap around the door and the depth of the strike plate pocket.
A new lock on a poorly hung door or a weak jamb with short screws offers minimal security. We ensure the strike plate is correctly aligned and secured with screws long enough to reach the stud, if present, effectively reinforcing the door frame against forced entry. This approach guarantees that your new lock provides the intended level of security, not just a cosmetic upgrade.
Hardware Matching and Keying to Your Needs
When replacing door hardware, matching the finish and style to your existing doors is often a priority. We carry a range of common finishes like brushed nickel, oil-rubbed bronze, and polished chrome to ensure your new lock blends seamlessly. Whether you are replacing a worn knob or upgrading to a more secure deadbolt, the aesthetic consistency of your home's exterior hardware is considered.
Beyond aesthetics, keying preferences are crucial. We can key your new deadbolt or knob to a new, unique key, or we can rekey it to match an existing key you already use for other doors on your property. This allows for convenient single-key access for all your entry points, simplifying your daily routine while enhancing security.
