Your New Keys and Our Service Commitment
After a lock change in Bladensburg, MD, you will receive a complete set of new keys. If you requested keying to an existing key, we ensure every new lock works seamlessly with it. Our technician will verify the operation of each lock, making sure the deadbolt throws fully and the latch retracts without effort. We encourage you to test the keys yourself before we leave, confirming your comfort with the new security.
We stand behind our lock replacement service. Should any issue arise with the newly installed hardware or our workmanship, you can contact us directly. Our goal is to provide a durable security solution that meets your needs for years to come. This commitment extends to ensuring the hardware is appropriate for your door's construction, providing lasting reliability.
More Than Just Replacing the Hardware
When you call for a lock replacement service, our approach begins with a full assessment of the door and frame. A common cause of lock failure is not the lock itself, but rather a misaligned door, worn strike plate, or an inadequate door jamb. We check these factors first because even a Grade 1 deadbolt will not perform optimally if the door system is compromised. Our technicians ensure the foundation is sound.
This diagnostic step often involves checking hinge screws, the door's plumb, and the strike plate alignment. If reinforcement is needed, such as longer screws into the stud or a reinforced strike, we address it before fitting the new deadbolt, knob, or lever. This attention to detail ensures the new lock functions correctly and provides the intended security, preventing common kick-in vulnerabilities.
What Types of Locks Can We Replace?
Our technicians are equipped to handle a wide range of residential lock replacement needs. This includes standard cylindrical locksets like knob and lever locks, as well as robust deadbolts. We install hardware from leading manufacturers, ensuring you receive quality products that match your home's aesthetic and security requirements. Whether you prefer brass, chrome, or oil-rubbed bronze, we can match your desired finish.
We also manage more complex replacements such as mortise lock bodies commonly found in older Bladensburg homes or specific storefront cylinders for residential ground-floor units. If you are upgrading for higher security, we can discuss Grade 1 and Grade 2 commercial-rated hardware suitable for residential applications. You can also request to have your new locks keyed alike, allowing one key to operate multiple entry points.

Can you replace just one part of my door lock, or do I need a whole new assembly?
