How do I know if my home locks need to be replaced or just repaired?

If your lock is sticking, hard to turn, visibly damaged, or more than 10–15 years old, it likely needs replacement. If the lock works but you need new keys or want to void old keys, rekeying is usually sufficient. Frederick Locks & Keys will assess your locks on-site and give you an honest recommendation — we never upsell a replacement when a repair or rekey will do. Call (240) 706-4799.

Lock Repair

Sticky locks, misaligned latches, broken key extractions, worn cylinders. We repair what can be saved and replace what can't — honest assessment every time.

Door Hardware

Knob sets, lever handles, handlesets, and entry sets. We match your home's style — from modern brushed nickel to traditional oil-rubbed bronze.

Security Assessment

Free walk-through of your home's entry points. We identify weak spots, recommend upgrades, and give you upfront pricing — zero pressure, zero obligation.

Every Entry Point

We Secure Your Entire Home

Most homeowners think about their front door lock and nothing else. But your home has 6–10 entry points that a burglar could target — and they rarely use the front door. We assess and secure every single one.

Front Door

Grade 1 or Grade 2 deadbolts, smart locks, decorative handlesets. Your front door gets the most attention from guests — and from burglars.

Back Door

Often the weakest link — many back doors have flimsy builder-grade hardware. We upgrade to proper deadbolts with reinforced strike plates.

Sliding Glass Door

Sliding door bar locks, pin locks, and track locks that prevent the door from being lifted off its track. A common break-in point that many homeowners overlook.

Garage Entry

The door from your garage into your house is an interior door that needs an exterior-grade lock. If someone gets into your garage, this is your last line of defense.

Basement Door

Walk-out basements, Bilco doors, and exterior basement entries. Heavy-duty locks and padlocks rated for outdoor exposure and forced-entry resistance.

Side Door & Windows

Side entries, mudroom doors, window locks, and casement window hardware. We secure every access point — not just the obvious ones.

Modern Security

Smart Locks for Modern Homes

Smart locks let you lock and unlock your door from your phone, create temporary codes for guests and contractors, get alerts when someone enters, and never worry about losing keys again. They're not just convenient — they're a genuine security upgrade when installed correctly.

The key phrase is "installed correctly." A smart lock that isn't properly aligned, paired, or configured is less secure than the dumb lock it replaced. We handle the complete installation — door prep, hardware mounting, app pairing, code programming, and a full walkthrough so you actually know how to use it.

We install all major smart lock brands and can recommend the right one for your door type, connectivity needs, and budget.

Know Your Lock Grades

ANSI Lock Grades Explained

Not all locks are created equal. Here's what the grade ratings actually mean for your home security — and why the locks that came with your house probably aren't good enough.

Builder-Grade

Grade 3

The minimum standard. What most homes come with from the builder. Adequate for interior doors — not for exterior doors.

200,000 cycle lifespan

2 door strikes to break

No pick or bump resistance

Fine for bedrooms & bathrooms

Recommended

Grade 2

Strong residential security. Good balance of protection and price. What we recommend for most Frederick County homeowners.

400,000 cycle lifespan

5 door strikes to break

Anti-pick pins standard

Schlage B60N, Kwikset 980

Maximum Security

Grade 1

Commercial-grade security for homes that need maximum protection. For high-value homes, high-crime areas, or homeowners who want the best.

800,000 cycle lifespan

10 door strikes to break

Pick, bump & drill resistant

Medeco, Mul-T-Lock, Schlage B660P

Free Service

Free Home Security Assessment

Not sure where your home's security stands? We'll walk through your entire property and evaluate every lock on every entry point — front door, back door, sliding doors, garage, basement, windows. We identify weak spots, recommend specific upgrades, and give you upfront pricing for everything. If you decide not to do anything, that's fine — there's absolutely no obligation.

Most homeowners are surprised to learn that their back door lock or garage entry is the weakest link — not their front door. A free assessment takes about 20 minutes and gives you a clear picture of where you stand.
