Why a New Lock Might Not Solve Your Security Problem
It is common for people to replace a 'failed' lock, only to find the new one still sticks or is loose. Often, the problem lies not with the lock itself, but with the door's alignment, worn hinges, a hollow jamb, or a misaligned strike plate. Installing a high-grade deadbolt into a soft, unreinforced door frame offers minimal real security.
Our service begins with a thorough inspection of your door's structure and alignment. We check the strike, the gap between the door and frame, and the integrity of the jamb before any new hardware is fitted. This approach ensures that a Grade 1 deadbolt provides its full protective capacity, integrated correctly into a robust door system.
What is Involved in a Professional Lock Replacement?
A professional lock replacement includes removing old, worn, or damaged hardware such as deadbolts, knob sets, or lever handles. We then prepare the door for the new lock, ensuring the boreholes are properly sized and aligned. Hardware is chosen to match your desired finish and security requirements, whether it is a Grade 1 commercial-rated deadbolt or a residential Grade 2 lock.
On request, new locks can be keyed alike to your existing keys, reducing the number of keys on your ring. We also inspect and, if necessary, reinforce strike plates and ensure the latch engages securely without binding. This detailed process ensures your new lock operates smoothly and offers reliable security for your Brandywine home.
How Do You Choose the Right Security Grade?
Selecting the appropriate security grade for your home's locks is crucial, especially after a security incident in your neighborhood or if your current hardware is decades old. ANSI (American National Standards Institute) ratings, such as Grade 1 or Grade 2, indicate a lock's durability and resistance to forced entry, with Grade 1 being the highest.
We help you evaluate your specific security needs based on your door type, frame strength, and your property's exposure. While a Grade 1 deadbolt offers superior protection, its effectiveness is maximized when installed in a robust door and frame assembly. We ensure the entire entry point is considered, not just the lock cylinder, providing a holistic security upgrade.
