Deadbolt Installation
Single- and double-cylinder deadbolts installed with reinforced strike plates and proper screw length, so the bolt seats fully into the frame.
New Locks Installed Correctly the First Time
A lock is only as strong as its installation. A quality deadbolt with a short bolt throw, a weak strike plate or a door that doesn't close cleanly won't protect your home the way it should.
Northwest DC Locksmith installs and replaces locks for homes and businesses across Washington, DC. Whether you're upgrading an old lockset, adding a deadbolt, switching to a smart lock or replacing hardware after a break-in, we fit it properly and make sure it works smoothly before we leave.
Lock Installation Services We Offer
We install and replace a wide range of locks and door hardware:
Lock Change & Replacement
Worn, damaged or outdated locks replaced with new hardware that fits your door. If your current locks still work well, we may recommend a lock rekey instead.
Smart Lock & Keypad Lock Installation
Keypad and smart locks installed, set up and tested on your door, including alignment adjustments so the motorized bolt doesn't bind.
Mortise and Rowhouse Door Locks
Many older DC homes and buildings use mortise locks. We work with these systems and can source compatible replacements or upgrades.
Commercial Lock Installation
Commercial-grade locksets, storefront locks and access hardware for offices and retail spaces. Learn more about our commercial locksmith services.
Frequently Asked Questions
How much does lock installation cost in Washington, DC?
Cost depends on the type of lock, whether you supply the hardware, and any door preparation needed. We give you a clear price before starting any work.
Can I buy my own lock and have you install it?
Yes. We can install hardware you've purchased. We'll check that it's compatible with your door and let you know about any issues before installing it.
Do you install smart locks?
Yes. We install and set up most popular smart and keypad locks, and we make sure the door and frame are aligned so the lock works reliably.
Should I change my locks or rekey them?
If your locks work well and you just need old keys to stop working, rekeying is usually the better value. If your locks are damaged or worn, or you want stronger security, a lock change is the right choice.
Can you match all my locks to one key?
In many cases, yes. When we install new locks, we can key them alike so a single key opens your front door, back door and deadbolts.

Book AppointmentWhy Professional Installation Matters
Most forced entries target the door frame and strike, not the lock itself. When we install a lock, we pay attention to the details that make it effective: bolt alignment, strike plate reinforcement, screw length and how the door closes. That’s the difference between a lock that looks secure and one that is.
For doors that need a higher level of protection, ask about high-security locks with restricted keys and pick- and drill-resistant cylinders.
Lock Installation for DC Homes and Businesses
We install locks in rowhouses, condos and apartments throughout the District through our residential locksmith services, and in offices and retail spaces across the city. If an existing lock is sticking or failing, we can often handle lock repair before recommending a replacement.
