Tightening a sagging door handle and latch plate with a screwdriver

What does a failing lock look like, and what is usually behind it?

Most lock trouble starts small. The key takes a little more wiggle than it used to. The deadbolt only throws if you lift the door slightly. The latch rubs the strike plate, and the door will not click shut unless you lean on it. People live with these quirks for months, and then the lock quits at the worst moment, usually when your hands are full or you are already late.

Here is how the common symptoms break down, and what we usually find when we open the lock up or look at the door around it:

One thing worth knowing up front: a large share of calls that start as a broken lock turn out to be a door problem. A door that has swelled, sagged on its hinges, or shifted in its frame will make a perfectly good lock bind. Fixing the lock without addressing the alignment only buys you a few weeks, so we check both.

  • Lock not turning: a worn or bent key, debris in the cylinder, a bolt binding against the strike plate because the door has moved, or a broken part inside the lock body.
  • Key stuck in lock: worn pins, a damaged key, or old lubricant and dirt gumming up the cylinder. Pulling harder with pliers is how a stuck key becomes a snapped key.
  • Jammed door lock: a bolt stuck halfway out, a latch that will not retract, or a failed spring or linkage inside the mechanism.
  • Loose door lock: a knob, lever, or deadbolt that wobbles because screws have backed out, the mounting hole is worn, or internal parts have loosened over years of use.
  • Latch problems: a latch that sticks, will not catch, or rubs because of misalignment, a bent latch bolt, or a worn strike plate.
  • Broken or damaged locks: a cracked housing, a snapped key, or damage left behind after a break-in attempt.

Should the lock be repaired or replaced?

Our starting point is repair, because it is usually the more economical route and it keeps hardware you already know and like. A lot of locks are sturdier than the replacements sold in hardware aisles, and a worn internal part is a small problem inside a solid lock.

But repair is not always the right call, and we will say so. If a lock is badly corroded, if the body is cracked, if parts are no longer made, or if the lock was never a good one to begin with, putting more work into it is money wasted. In those cases we will walk you through lock replacement and let you decide.

Here is roughly how we weigh it:

  • Repair makes sense when the problem is alignment, a worn or dirty cylinder, loose mounting, a weak spring, or a single failed internal part in an otherwise sound lock.
  • Replacement makes sense when the lock body is cracked, rust has eaten into the mechanism, parts cannot be sourced, or the lock is a loose-fitting low-grade unit that will keep failing.
  • If the lock works fine but you are worried about who else holds a key, that is a different job. A lock rekey changes which key operates the lock without touching its condition.

How does a lock repair call work?

We keep the process simple and we explain each step as we go, so you are never guessing what the work involves or why.

  1. You call (213) 577-1366. A person answers at any hour. Tell us what the lock is doing, what kind of door it is on, and whether you can currently get in and out.
  2. We talk through the symptoms and tell you what is likely going on, plus what you should avoid doing in the meantime, such as forcing a key or spraying the wrong lubricant into the cylinder.
  3. A technician comes to you in a mobile service van carrying common parts and tools. When we call, we will be straightforward about travel to San Dimas rather than promise something we cannot keep.
  4. On arrival we look at the lock, the key, the latch, the strike plate, and the door's fit. We check whether the trouble is the hardware or the door around it.
  5. Before any work starts, we tell you what we found, whether repair or replacement is the better fit, and what is driving the cost. You approve the work or you do not.
  6. We make the repair, then test the lock repeatedly with the door open and closed, from both sides, with every key you have. We would rather find a remaining issue in your doorway than have you find it tomorrow morning.

How do we repair deadbolts, mortise locks, latches, and loose hardware?

Different locks fail in different ways, so the fix depends on what is actually in your door.

Deadbolt repair usually comes down to the bolt, the cylinder, the thumbturn, or the strike. A deadbolt that is hard to throw is often fighting a misaligned strike or a door that has shifted. A deadbolt where the key turns but nothing moves often has a broken connecting piece inside. Both are commonly repairable without replacing the whole lock.

Mortise lock repair is a more specialized job. A mortise lock sits in a deep pocket cut into the edge of the door and holds a latch, a deadbolt, and a set of internal levers and springs in one body. They are found on older residential doors and on many commercial doors. Because the parts are individually serviceable, a mortise lock can often be cleaned, adjusted, and rebuilt rather than swapped. We will be honest, though: on some older mortise bodies, parts are hard to find, and that can tip the decision toward a different lock.

Latch repair covers knobs and levers that stick, retract slowly, or fail to catch. Sometimes the latch itself is worn or bent. Just as often the fix is moving or reshaping the strike plate so the latch lands where it should.

A loose door lock is one of the quicker repairs. We tighten and re-seat the hardware, deal with stripped or enlarged screw holes so the fix actually lasts, and check the internal mechanism for wear while we are in there.

A key stuck in a lock is another common call. If the key is intact, we work it out carefully and look for why it stuck. If it has snapped, that becomes a broken key extraction, which has its own tools and its own approach.

What affects the cost of lock repair?

We do not quote numbers on a web page because the honest answer depends on the lock in front of us. What we can do is tell you exactly what moves the cost up or down, so nothing on the estimate comes as a surprise.

The best thing you can do to keep a repair on the lighter-cost side is to call early. A lock that is merely stiff costs less to fix than one that has jammed shut or been forced.

  • The type of lock: a standard knob, a deadbolt, a mortise lock, and a commercial-grade lockset each involve different parts and different amounts of labor.
  • The cause: tightening a loose lock is a different job from rebuilding an internal mechanism or correcting a shifted door frame.
  • Parts: whether the needed part is common or has to be sourced for an older or specialty lock.
  • Whether the door is part of the problem: alignment work on the door, latch, or strike adds time.
  • The time of day: nights, weekends, and holidays involve different scheduling than a weekday daytime visit.
  • Travel: San Dimas is roughly 40 miles from our Westwood storefront, and distance is a fair thing for us to factor in and tell you about up front.
  • Repair versus replacement: if we find that replacing the lock is the better route, the scope and the estimate change, and we will tell you before proceeding.

What about commercial lock repair?

Commercial lock repair follows the same logic, with a few differences that matter. Business doors are used all day, so wear shows up faster, and a lock that will not secure the door is more than an inconvenience: it affects when you can open and close. We try to treat that urgency seriously.

Storefront doors often combine several parts that can each fail: the lock, the latch, a closer that controls how the door swings, and exit hardware. A door that slams or does not latch can look like a lock fault when the real culprit is the closer, which is a separate repair we cover under door closer repair. For storefront locks specifically, our page on storefront lock repair goes deeper.

We repair commercial hardware on site where we can and will tell you if a lock has reached the point where replacing it is the better use of your money.

What do lock repairs in San Dimas usually involve?

San Dimas has a mix of building types, and each one tends to produce its own kind of lock call. Everything here is within the 91773 ZIP code, so it is one city but several different kinds of door.

Much of the city is made up of suburban tracts built from the 1960s through the 1980s. Homes of that age often still have original or mid-life hardware that has been opened and closed for decades. That is exactly the situation where a repair, rather than a replacement, can make sense: the locks are worn but the doors and frames around them are sound.

The Via Verde planned community, in the southwest near Puddingstone Reservoir, adds townhomes, condos, and golf-course homes. In a shared-wall community, front-door deadbolts and latches take regular daily use, and a sticking lock there is usually a good candidate for adjustment. If what you really want is to change who has access after a move, that is a rekey rather than a repair, and we can steer you that way.

In the San Dimas Canyon area and the northern canyon neighborhoods, the properties are larger and include equestrian lots. Gates, barn doors, and tack-room latches live outside, and canyon winds carry dust into exterior hardware. Dust packs into cylinders and latches and makes them stiff. For driveway and pasture hardware, see our gate lock repair page. Mobile home parks along the Arrow Highway corridor have their own door and latch hardware, and we can service those as well.

Downtown San Dimas, around the Bonita Avenue district, has a western-themed streetscape with older storefronts that carry legacy commercial hardware. Older commercial locks and latches are often worth repairing because they still work well mechanically, and replacing them can mean changing the look of a historic-style storefront. Foothill Boulevard and Lone Hill Avenue also carry plenty of commercial doors.

Then there is the weather. San Dimas is an inland valley city, and summer highs run well above the coastal basin. Doors expand in the heat, and sticking latches in late summer are routine. A door that fits fine in March can rub in August, and then a latch or deadbolt that seemed fine starts to bind. Before we replace anything, we check whether the fix is adjusting the strike or easing the fit, rather than assuming the lock itself has failed.

Why call Wilshire Lock & Key for lock repair?

We have been in business since 1987, and that history shows up in how we approach a repair: we have seen most of the ways locks fail, including old hardware that newer technicians sometimes have never worked on.

We are one company with a storefront at 10740 Wilshire Blvd in Westwood and our own mobile service vans. You are not passed along to a dispatcher who subcontracts the job to whoever is closest. The person who talks to you is part of the company that does the work.

David, the owner and lead technician, oversees the work. That matters most when a repair call is borderline: whether to repair, replace, or leave a lock alone is a judgment call, and we make it in your favor rather than selling you hardware you do not need.

A note about licensing: California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith you are thinking of hiring to show it to you, and verify it. That is a good habit no matter who you call.

If the problem is bigger than a stuck lock, we can help in other ways. For a locked-out situation, see house lockout. For how our vans work across the area, see mobile locksmith service.

What should you do before we arrive?

A few small choices can keep a repair simple and prevent a bad lock from getting worse. Here is what we recommend while you wait.

  • Do not force the key. Turning harder or using pliers on a stuck key is the most common way to turn a simple repair into a broken key.
  • Do not spray heavy oil into the cylinder. It can attract dust and make things gummy over time, which is especially true in dusty, windy spots.
  • If the door is open, leave it open, and do not lock it until you know the lock works. A lock that can trap you outside, or one that will not unlock from the inside, should not be tested repeatedly.
  • Gather every key you have for that lock, including the spares. A worn key is sometimes the real problem, and we want to test all of them.
  • Note when it started and what changed: hot weather, a recent door adjustment, a rough closing, or an attempted break-in. Small details help us find the cause faster.
  • If the door will not secure and you need to leave, tell us when you call. We can discuss a temporary option to protect the property until the repair is done.

Frequently asked questions

Can you repair my lock the same visit, or will I need to wait for parts?

Often we can repair it on the same visit, because our vans carry common parts and tools. Older locks, mortise bodies, and specialty hardware sometimes need a part that has to be sourced. When that happens, we tell you before starting, and we can discuss a temporary way to keep the door secure until the part arrives.

My key is stuck in the lock. What should I do?

Stop pulling and do not use pliers. If the key is still in one piece, wiggle it gently without turning, and call us at (213) 577-1366. If it has already snapped, that is a broken key extraction, which uses different tools. Forcing it risks pushing the broken piece deeper.

Why does my lock stick more in summer?

San Dimas gets inland valley heat, and doors expand in hot weather. That can make latches and deadbolts rub against the strike plate or frame. Dust blown in from the canyon area can also stiffen exterior hardware. Often the fix is adjusting the strike or cleaning the lock, not replacing it.

Is it cheaper to repair a lock than replace it?

Usually repair is the more economical route when the lock body is sound and the problem is alignment, wear, or a single failed part. But if the lock is corroded, cracked, or a poor-quality unit, replacement can make more sense. We tell you which applies before we start work.

Do you repair mortise locks and older hardware?

Yes. Mortise locks are serviceable, and we can often clean, adjust, and rebuild them instead of replacing them. The honest limit is parts: some older mortise bodies are hard to find parts for. If that is the case, we will tell you and explain the alternatives.

Why is my door lock loose or wobbling?

Usually the mounting screws have backed out or the screw holes have worn out, though internal wear can also loosen a knob or lever. Tightening it is often a quick fix, but if the holes are stripped, we repair them so the fix holds rather than tightening it again next month.

Can you fix a lock that was damaged in a break-in attempt?

Often yes, depending on the damage. Bent latches, damaged strike plates, and scarred cylinders can sometimes be repaired, but a cracked housing or a compromised lock should be replaced. We assess the lock and the door frame and tell you plainly which is the safer choice.

Do you do commercial lock repair in San Dimas?

Yes. We repair locks, latches, and related hardware on business doors, including older storefront hardware. We also check whether a door problem is really a closer or exit hardware issue, since those can mimic a bad lock.

What hours can I call for lock repair?

Our phone, (213) 577-1366, is answered 24 hours a day, 7 days a week, year-round. If your lock fails at night or on a weekend, call anyway. We will tell you honestly what can wait until morning and what needs attention now.
