The Process: Ensuring a Lasting Solution
Before any new hardware is fitted, Q 24/7 Lock Service technicians carefully assess your existing door and frame. We check for proper door alignment, the condition of the strike plate, and the integrity of the jamb. Often, what appears to be a failed lock is actually a misaligned door or a worn strike, which we address to prevent future issues.
This diagnostic step is crucial because even a Grade 1 commercial-rated deadbolt will not offer maximum security if the door frame is weak or the strike plate is poorly anchored. We ensure that any new installation, whether it is a fresh Kwikset SmartKey deadbolt or a more robust Schlage keypad lever, is mounted securely into a reinforced structure, providing a solid defense against forced entry.
Understanding Your New Keys and Warranty
Upon completion of your lock change service, you will receive a new set of keys designed to operate your upgraded hardware smoothly. We can, upon request, key your new locks to match existing keys you already use for other entry points, minimizing the number of keys on your ring. This ensures convenience without compromising security.
All hardware installed by Q 24/7 Lock Service comes with manufacturer warranties, and our installation work is guaranteed. If you experience any issues related to the installation, we are available to address them. You will also receive clear instructions on how to care for your new locks to ensure their longevity and performance.
