Why is my lock not turning, sticking, or jammed?

A lock that fights you is rarely a lock that has to be thrown away. Almost always, something specific has worn, shifted, or gummed up: a spring that has gone weak, a pin stack that is binding, a latch bolt that no longer lines up with its strike plate, or a mounting screw that has backed out over years of use. Lock repair is the work of finding that one cause and correcting it, so the hardware you already own keeps doing its job.

San Marino adds its own twist to this. The city is almost entirely single-family homes, built largely in the 1920s and 1930s in Spanish Colonial Revival, Tudor, Monterey, and other period styles on large lots. Door hardware on houses like that has often been in daily service for generations. It tends to be well made, but it is old, and old hardware wears in predictable ways. A key that used to slide in now catches. A deadbolt that once threw smoothly now needs a shoulder against the door. A knob wobbles in your hand.

This page is about repair: sorting out what is wrong and fixing it where fixing makes sense. If you are already looking at a locked-out situation, our house lockout service is the better starting point, and if the lock is beyond saving, we explain replacement further down and link to it. Everything else, from a stiff cylinder to a loose latch, belongs here.

Which lock problems can be repaired instead of replaced?

Here are the problems we see most often and what is usually behind each one. These are the typical causes, not a diagnosis of your particular door, since we need to put hands on the lock to be sure.

  • Lock not turning: the key goes in but the cylinder will not rotate. Common causes include worn or dirty pins, a bent or badly copied key, a swollen door pushing the bolt against the strike, or a cylinder that has seized from old lubricant and grit.
  • Key stuck in lock: the key will not come back out. This is often a worn key, debris in the keyway, or a cylinder halfway between positions. If the key has actually snapped off inside, that is a separate job, covered by our broken key extraction service.
  • Jammed door lock: the bolt or latch will not retract or extend. The usual culprits are a door that has shifted so the bolt binds, a broken internal spring, or a latch mechanism full of old residue.
  • Loose door lock: the knob, lever, or deadbolt wobbles or rotates in the door. Often the fix is as simple as properly seating and tightening the hardware, but it can also mean a stripped bore, a cracked rose, or a worn spindle.
  • Latch repair: the door will not stay closed, or it rattles in the frame. We look at the latch bolt, the strike plate position, and whether the door itself has dropped or swollen.
  • Deadbolt repair: the bolt drags, only half-throws, or the thumb turn spins without moving anything. A broken tailpiece or connecting bar inside is a common reason.
  • Mortise lock repair: the heavy lock body set into the edge of the door sticks, fails to latch, or has a worn spring or lever inside. This is specialist work, and we cover it in its own section below.
  • Broken or damaged lock repair: a lock that has been forced, kicked, or partly pried. If the lock body and door are still sound, we can often repair or rebuild rather than start over.

How does Wilshire Lock & Key repair a lock, step by step?

We work the same way whether the lock is on a 1930s front door or a side gate. The aim is to find the real fault before touching anything, and to tell you honestly whether repair is the right call.

  1. You call (213) 577-1366. A person answers, any hour, any day. Tell us what the lock is doing, what kind of door it is, and whether you can still get in and out.
  2. We ask a few specific questions: does the key turn partway, does the problem happen only in hot weather, is the door hard to close, has the lock been serviced before. Those answers often point to the cause before we arrive.
  3. A technician comes to the property. We work from our Westwood storefront and our mobile vans, and San Marino is roughly 22 miles from our base.
  4. We test the lock with the door open and closed. Many problems that look like a bad lock are really a door that has moved, so we check alignment of the latch, bolt, and strike plate first.
  5. We take the hardware apart as far as needed, inspect the springs, pins, levers, and spindles, clean out old residue, and replace worn internal parts where they exist.
  6. We reassemble, adjust the strike or the door fit if that was part of the problem, and test the lock repeatedly with the key and from inside.
  7. Before we finish, we tell you what we found, what we did, and whether anything else is wearing and worth watching. If repair is not the sensible route, we say so and explain the alternatives before any replacement begins.

Should I repair the lock or replace it?

Repair is usually the more economical route when the lock body is basically sound and the fault is a worn part, a misalignment, or a build-up of dirt. It is also the right call when the hardware matters to the house. On a period home, original hardware is part of the character of the door, and finding a modern substitute that fits the same mortise pocket and looks right is not always easy.

Replacement makes more sense in a handful of situations. The lock may be cracked or badly corroded, or the internal parts may no longer be obtainable. It may be a low-grade lock that has failed repeatedly. You may also simply want better security than the existing lock can give. In those cases, our lock replacement service is the next step, and we will tell you plainly when we think repair is only delaying the inevitable.

We do not push replacement when a repair will do the job, and we do not patch a lock that should be swapped out just to keep a visit short. The point is to leave you with a door that works and an honest picture of its condition.

What affects the cost of lock repair in San Marino?

We do not quote numbers on a web page, because a lock that will not turn can come from a dozen different causes and the work behind them varies a great deal. What we can do is tell you what moves the cost up or down, so nothing surprises you.

The biggest factor is what is actually wrong. Tightening a loose door lock or adjusting a strike plate is a lighter job than rebuilding a mortise lock body with worn internal parts. The type of lock matters too: a standard residential cylinder is a different proposition from a vintage mortise set, or a high-security cylinder with restricted keys.

Parts availability plays a role. If an original component is still obtainable or can be reconditioned, repair is straightforward. If it has to be sourced or made to suit, that takes more time. The condition of the door also counts, since a swollen or dropped door may need fitting work in addition to the lock repair.

Finally, timing and location. Calling in the middle of the night is different from booking a daytime visit, and San Marino sits some distance from our Westwood base. We will explain the factors that apply to your situation when you call, and we will talk through the work before we start, so you can decide with full information.

How does mortise lock repair work on San Marino's period homes?

Many San Marino houses still carry the original mortise locksets and period door hardware they were built with. A mortise lock is not a cylinder bolted onto the door face. It is a rectangular steel and brass body set into a pocket cut in the edge of the door, with a latch, a deadbolt, and an arrangement of levers or springs inside, operated by a key, a knob, and sometimes a thumb turn. That construction is part of why these locks last so long, and also why a careless replacement can damage the door.

Typical mortise problems include a latch that sticks halfway, a deadbolt that will not fully throw, a spring that has finally given out, a worn key that no longer lifts the levers properly, and a knob spindle that has loosened and wobbles. Many of these are repairable by opening the case, cleaning, and replacing or adjusting the worn pieces. That route keeps the original plate, trim, and look of the door, which owners of Spanish Colonial Revival, Tudor, and Monterey homes usually care about.

Climate plays a part too. San Marino is inland in the San Gabriel Valley, with hot, dry summers and mild winters. It is far enough from the coast that salt-air corrosion is not the issue. Heat is. In summer, wood doors can swell and shift, and older mortise hardware that fit perfectly in spring can start to bind or misalign. If your lock only acts up on the hottest days and behaves in winter, that pattern is a strong hint that the door and the hardware are fighting each other, not that the lock itself has failed. Adjusting the fit is often the cure.

Lock repair around Lacy Park, Huntington Drive, and Mission Street

San Marino is a small city with one ZIP code, 91108, and the work looks different depending on which part of it you are in.

Around the Lacy Park area and the estate streets nearby, the typical call involves an older front door and a lock that has begun to stick or fail. When one of those locks stops working with someone on the wrong side of the door, it turns into a house lockout first and a repair second. We open the door in the least destructive way we can, then repair the lock so it does not happen again.

Near the Huntington Library area and along the Huntington Drive corridor, many properties are large fenced lots, with side doors and gates that get used more than people realize. A gate latch that no longer catches or a side-door deadbolt that has gone stiff can leave a property effectively open. For gates in particular, our gate lock repair page goes into the specifics.

Around San Marino High School, we often see the aftermath of home sales. New owners find that keys do not work smoothly, or that old hardware is worn after years of use, and they want everything confirmed working and secure. If you want every key changed as well, a lock rekey is the companion service to repair, and the two often go together on the same visit.

On the Oak Knoll border near Pasadena and in the El Molino Viejo and Old Mill area, the same pattern holds: period houses with original hardware, large lots, and doors that have seen a lot of summers. In every one of these areas, the first step is the same. We look at the lock and the door together before deciding what needs to be done.

What about commercial lock repair on Mission Street?

San Marino has a small Mission Street business district, and the shops there have the same lock problems as homes, with more traffic going through the door. A commercial lock repair usually involves a storefront deadbolt, a latch that sticks as the door is used all day, or a cylinder that has seized after years of daily use. The difference is that a business cannot easily leave the door unsecured while it waits.

We handle commercial lock repair with the same approach: find the fault, repair what can be repaired, and be honest when hardware has reached the end of its life. For the full scope of door and frame work on shopfronts, see our storefront lock repair page. If you manage a business and are not sure whether the problem is the lock, the door closer, or the frame, describe it on the phone and we will help sort out which it is.

Why call Wilshire Lock & Key for lock repair?

We have been in business since 1987, and David, the owner, is the lead technician and oversees the work. That means the person who built the company is the person accountable for how a repair is done, and not a call-center script.

We are one company with a storefront at 10740 Wilshire Blvd in Westwood and our own mobile service vans. There is no dispatch middleman passing your job to whoever is available. The phone is answered 24 hours a day, 7 days a week, year-round, at (213) 577-1366, and we serve 140 cities across Los Angeles and Ventura counties, San Marino among them.

We also prefer to explain things. If you are looking for a residential locksmith who will tell you what is wrong, what the options are, and which one is the lighter-cost option, that is how we work.

One more thing worth knowing: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith you call for it before work starts. It is a reasonable question, and any reputable company should be comfortable with it.

What can I do before the technician arrives?

A few simple steps can make the visit quicker and help avoid making the problem worse.

  • Do not force the key. Bending or snapping a key inside a stiff lock turns a repair into a bigger job.
  • Do not spray heavy oil into the cylinder. Thick lubricants collect dust and can make a sticky lock worse over time.
  • Note when the problem happens: only in the heat, only when the door is closed, only from outside. That detail is useful.
  • Keep the door closed and the area clear. If you can still get in and out, leave the lock as it is until we look at it.
  • Have any spare keys ready, since a comparison against a known-good key can reveal a worn key as the cause.
  • If you are locked out or a door will not secure and you need help urgently, call us and mention it, and our emergency locksmith service covers those situations.

Frequently asked questions

Can a sticking lock really be repaired, or do I have to replace it?

Usually it can be repaired. Sticking is most often caused by wear, dirt, a weak spring, or a door that has moved out of alignment, and all of those can be corrected without replacing the lock. We will tell you plainly if the lock is too worn or damaged to be worth repairing.

Why does my lock only stick in the summer?

In San Marino's hot, dry summers, wood doors can swell and shift, which can push a bolt against its strike plate or misalign older mortise hardware. If the lock works well in cooler months, the door fit is often the cause, and adjusting it can fix the problem.

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

Stop pulling or twisting hard, because that can snap the key. Try wiggling it gently while applying slight pressure in each direction. If it will not come out, call us at (213) 577-1366. If it has broken, we can extract it and repair the lock afterward.

Can you repair the original mortise locks on my 1920s or 1930s home?

In many cases, yes. Mortise lock repair is a core part of working on older San Marino homes. We open the lock body, inspect and clean the parts, and replace or adjust what is worn, so the original hardware and look of the door stay intact where possible.

Do you repair deadbolts and loose door locks too?

Yes. Deadbolt repair, loose door lock repair, and latch repair are everyday work for us. A loose lock is often just a matter of reseating and securing the hardware, though a stripped bore or worn spindle may need more work.

How much will my lock repair cost?

We do not give prices on this page because the cost depends on the cause. It is shaped by the type of lock, what has failed, whether parts are readily available, the condition of the door, and the time of day. We talk through the work with you before we start.

Do you do commercial lock repair as well as residential?

Yes. We handle residential lock repair and commercial lock repair, including storefront locks in places like the Mission Street business district. The approach is the same: find the fault, repair what is worth repairing, and be honest about what is not.

Is it safe to keep using a lock that is starting to stick?

It is risky to wait. A lock that sticks today can fail completely tomorrow, often at a bad moment, and forcing it can damage the key or the internal parts. It is usually easier and more economical to have it looked at while it still works.

How do I know a locksmith is properly licensed?

California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith for it before they begin work, and check that it is current. It is a normal request and a good habit to adopt.

Do you answer calls at night and on weekends?

Yes. Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, all year, so you can reach a person at any hour if a lock fails.
