Ensuring Proper Fit and Function
Many lock issues stem from door problems rather than the hardware itself. Before installing a new deadbolt, knob, or lever, our technician assesses the door frame, strike plate alignment, and the existing door gap. This preliminary check is critical to prevent future issues, ensuring that even a Grade 1 commercial-rated deadbolt provides genuine security against forced entry.
We carefully adjust the strike plate location and confirm the door closes squarely into the jamb. Installing new hardware then involves precise boring and securing with appropriate length screws that anchor into the door frame, not just the trim. This attention to detail means your new lock will operate correctly from day one.
Keying Options and Post-Installation Steps
Once your new locks are installed, you have options for keying. We can key new hardware to a new set of keys, or if you prefer, we can rekey the new locks to match your existing house key, reducing the number of keys on your keyring. This service is performed on-site, ensuring immediate functionality.
After installation, our technician tests each lock thoroughly to confirm smooth operation and proper latching. We will then walk you through its features, answer any questions, and ensure you are comfortable with your new security. You will receive all new keys, ready for immediate use.
Upgrading Your Home Security
Replacing old or damaged locks is a direct way to enhance your home's security. Q 24/7 Lock Service installs a range of hardware, from standard residential knobs and levers to high-security Grade 1 deadbolts, which offer superior resistance to picking, bumping, and drilling. We help you select hardware that not only meets your security needs but also complements your home's aesthetic.
Whether you are updating worn brass hardware, replacing a broken mortise lock body, or seeking to reinforce a vulnerable entry point after a security concern in your neighborhood, we provide options that blend durability with design. We also reinforce strike plates and jambs, turning a simple lock change into a comprehensive security upgrade.
