Sometimes a lock has simply had its run. It was bent when someone tried to force the door, the finish has worn through, or it’s the basic knob the builder put in, never meant to be the only thing keeping someone out. Replacing it is a chance to choose a stronger lock, a style that suits your home, or a keypad so nobody needs a key at all. Master Locksmith installs new residential locks across Silver Spring and the surrounding counties, and we fit each lock to its door so it closes and locks without a fight.
We can supply the lock or install one you’ve already bought. Our technicians fit new locks in Montgomery and Prince George’s counties, Washington DC, Howard and Anne Arundel counties, Baltimore and Northern Virginia. We’re open Monday through Saturday, 8am to 8pm, and the number for a quote is (301) 888-5152.

What You Get With a New Lock From Us

A new lock is only as strong as its installation. A deadbolt that doesn’t fully extend, or a strike held on by short screws, gives up much of what you paid for. We take care of those details.

Help Choosing the Right Lock

Locks are graded under an industry standard (ANSI/BHMA) from Grade 3 up to Grade 1, with Grade 1 the toughest. For most front doors we suggest Grade 2 or better, and we'll explain the options in plain language.

Stronger Strike Plates

Most forced entries break the door frame, not the lock. We can fit a heavier strike plate with long screws that reach the framing behind the jamb, so a kick meets the house framing instead of a thin strip of trim.

Keyed to Match

New locks come with their own keys. We can set them to match your other locks, so the new deadbolt and the old back door still share one key.

A Clean Fit on Any Door

Older doors, steel doors and doors with unusual measurements need some adjusting. We drill, chisel and shim as needed so the lock sits flush and the bolt extends all the way.

Old Hardware Taken Away

We remove the old locks and take them with us if you don't want them. You're left with working locks and nothing to clean up.

When It's Time for a New Lock

Rekeying and repair cover a lot of ground, but these situations usually call for replacement.

After Someone Forced the Door

If a door was kicked or pried, the lock and strike are usually bent even if they still turn. We replace them and reinforce the frame so the door is stronger than it was.

Worn Out or Broken Locks

Locks that wobble, grind when you turn the key or have broken parts inside often cost more to fix than to replace.

Upgrading Your Security

Moving from a basic knob to a solid deadbolt, or adding a deadbolt to a door that only had a knob lock, is one of the simplest ways to make a home harder to break into.

New Style or Finish

Renovating? We can install new handle sets and levers in the finish you choose and keep them consistent from door to door.

Going Keyless

Keypad deadbolts and smart locks mean no more lost keys. We install them and line up the bolt so the motor isn't straining every time it locks.

Thinking about a smart lock? Our smart lock installation page covers keypads, app locks and what to check before you buy one.

How a Lock Replacement Visit Works

1. Call or Send a Request

Start with a call to (301) 888-5152 or a message through the form. Tell us which doors, what's on them now, and if you already have new locks or want us to bring them.

2. Get a Clear Quote

You get a clear price for the locks and the installation before anything is scheduled.

3. A Technician Heads Your Way

A technician arrives with the locks we agreed on and the tools for drilling, chiseling and fitting.

4. The Work Itself

We remove the old hardware, prepare the door if it needs it, and install the new lock and strike.

5. Testing Before We Finish

We try every lock with every key, adjust the strike until the bolt slides in cleanly, and check that the door latches without a push.

6. Before We Leave

You get your keys, we show you how anything new works, like setting keypad codes, and the old locks leave with us unless you want them.

Lock Replacement Questions

Should I replace or rekey my locks after moving?

If the locks work well and you like them, rekey. If they’re worn, low grade or not your style, replace them. Either way, the old keys stop working.

Can you add a deadbolt to a door that doesn't have one?

Yes. We drill the door and frame, fit the deadbolt and install a strike plate with long screws. It’s one of the most useful upgrades for any exterior door.

Do I need to buy the lock myself?

No. We can bring good quality locks for you to choose from, or install one you’ve already bought. If you’re buying your own, send us the model first so we can confirm it fits your door.
