Lock Repair in Washington, DC

Lock Repair DC


A lock that sticks, drags or refuses to turn is usually a sign that something is wearing out. Left alone, a stiff cylinder or a sagging latch can end with a key snapped off in the lock or a door that will not close behind you. The Locksmith DC Company repairs locks on homes and businesses across Washington, DC, with the aim of getting your existing hardware working properly again.

Many problems that look like a bad lock actually start with the door, the strike plate or a worn key. We find the cause first, then fix what is wrong, whether that means servicing a cylinder, adjusting a strike, replacing a worn internal part or re-securing loose hardware.

If a repair will not hold up, we will say so and explain your options, including lock rekeying or a full lock change. We are open every day from 7:00 AM to 11:00 PM.

Common Problems

Lock Problems We Repair

Most repair calls fall into one of these four groups. Tell us what you are seeing when you call, and we can usually narrow down the cause.

Jammed Locks and Stuck Cylinders

Dirt, old lubricant, worn pins or a bent tailpiece can stop a cylinder from turning. We service and repair the cylinder so the key turns smoothly again.

Keys That Won’t Turn

A key that goes in but will not turn usually points to a worn key, a door that has shifted, or a damaged pin. We find out which one before deciding on a fix.

Deadbolts and Latches That Won’t Catch

When a bolt drags, stops halfway or misses the strike, the cause is often alignment. Adjusting or reinforcing the strike usually solves it.

Loose, Worn or Damaged Hardware

We tighten, re-mount or fit new parts to wobbly knobs, drooping levers and loose deadbolts before they fail completely.

How We Repair Locks


Every repair starts with a few simple checks. We operate the lock with the door open and closed, look at how the bolt lines up with the strike, check the condition of your key, and take the lock apart when needed. That tells us whether the lock is the real problem or only the part showing the symptom.

Typical Lock Repairs

  • Servicing sticky cylinders and lock bodies
  • Freeing jammed cylinders and removing broken keys
  • Replacing worn springs, cams, tailpieces and spindles where parts are available
  • Adjusting or moving strike plates so bolts and latches catch cleanly
  • Tightening and re-securing loose knobs, levers and deadbolts
  • Repairing commercial mortise locks, storefront cylinders and exit devices

Repair, Rekey or Replace?

Repair makes sense when the lock is sound but a part, the alignment or the key is causing trouble. Rekeying is the right choice when the lock works well but old keys need to stop working, for example after a move or a lost key. Replacement is the better call when the lock body is cracked, the manufacturer no longer makes parts, a break-in damaged the hardware, or the lock is too weak for the door.

We explain which option fits and why, so you do not pay to replace a lock that only needed an adjustment, or keep repairing one that is past its useful life.

Lock Brands We Repair

At home, we work on Schlage, Kwikset, Yale and Baldwin locks and deadbolts. For businesses, we service commercial hardware from Schlage, Yale, Corbin Russwin and Sargent, exit devices from Von Duprin and Detex, and LCN door closers.

Lock Repair in Washington, DC


Washington’s older housing creates its own repair calls. Rowhouses in neighborhoods such as Petworth, Shaw and Capitol Hill often have doors that have settled over the decades, so a deadbolt that once lined up perfectly now drags against the strike. Humid summers can swell wooden doors and make the problem worse.

Many older homes still have original mortise locks. When parts are available, repairing them keeps the door’s character and avoids cutting new holes. In condo and apartment buildings, check with management before work on an entry lock, especially if the building uses a master key system.

For businesses, locks on high-traffic doors wear faster. We repair storefront cylinders, mortise locks and exit devices for offices, shops and restaurants so doors secure properly at closing time. Learn more about our commercial locksmith services.

How Much Does Lock Repair Cost in DC?


The cost of a lock repair depends on what is wrong, the type of lock, whether parts are needed, and how many locks we work on during the visit. A sticky residential cylinder that only needs servicing costs far less than a commercial mortise lock that needs internal parts.

We explain the problem and quote the work before we start. If a repair would cost close to the price of a new lock, we will tell you, so you can choose between repair, rekeying and replacement. Starting prices for common services are listed in our DC locksmith cost guide.

Frequently Asked Questions

Can a jammed lock be repaired, or does it need to be replaced?

Most jammed locks can be repaired. Dirt, worn pins, a bent tailpiece or a misaligned strike are common causes, and we can usually fix each one without replacing the lock. We recommend replacement only when the lock body or key parts have broken or worn beyond repair.

Why won’t my key turn in the lock?

The most common reasons are a worn or poorly copied key, a dirty or dry cylinder, or a door that has shifted so the bolt binds. Try the key with the door open: if it turns easily then, the problem is alignment rather than the lock. Avoid forcing the key, since a snapped key makes the repair harder.

Should I spray WD-40 into a sticky lock?

We do not recommend it. Oil-based sprays can attract dust and gum up the pins over time. A dry lubricant made for locks is a better short-term fix, and a lock that keeps sticking needs servicing.

My deadbolt only locks when I push or pull on the door. What is wrong?

That is almost always an alignment problem between the bolt and the strike plate, usually because the door has sagged or swelled. Adjusting the strike, and sometimes the door, usually fixes it without replacing the deadbolt.

Do you repair commercial locks and panic bars?

Yes. We repair commercial mortise locks, storefront cylinders and exit devices, including Von Duprin, Detex, Sargent and Corbin Russwin hardware. A worn door closer can also stop a door from latching, so we check the whole door, not just the lock.

Is it cheaper to repair or rekey a lock?

They solve different problems. A repair fixes a lock that does not work properly, while rekeying changes which key operates a lock that already works well. If you need both, we can often handle them in the same visit.
