When does a lock need to be replaced instead of repaired?

Most lock trouble does not call for a new lock. A key that sticks, a handle that has come loose, or a latch that catches only some of the time can often be fixed in place. But some problems mean the lock is finished, and patching it only delays the day you get locked out or locked in.

Age is a big factor. Hardware that has been used every day for decades wears at the points where the key meets the pins and where the bolt meets the strike. The key starts to feel loose in the cylinder, then it spins without moving the bolt, and eventually it fails at the worst moment. Outdated hardware is the other common reason. A lock whose parts are no longer made, or one that has been copied so many times you have lost track of who holds a key, is often worth retiring even though it still turns.

Here are the situations where we usually recommend replacing the lock rather than repairing it:

  • The key turns but the bolt does not move, or the cylinder spins freely.
  • The lock body is cracked, bent, or pried after a break-in attempt.
  • A key snapped inside and the cylinder was damaged during removal.
  • The deadbolt has been forced into a misaligned door for years and is worn out from it.
  • The finish has worn through and the mechanism feels gritty or loose.
  • You have lost keys, moved into a place with unknown key holders, or ended a tenancy, and the lock is also old or low quality.
  • The hardware is too weak for what the door protects, and you want a real security lock upgrade.

Which locks do we replace?

We replace locks on homes, apartments, and businesses. The work is the same in principle, but the hardware and the door conditions differ, so we treat each door on its own terms.

Front door lock replacement is the most common request. That can mean a deadbolt, a knob or lever set, or a combination of the two. House lock replacement often covers every exterior door at once: front, back, side, and any door that leads in from a garage. If you want to add or upgrade a deadbolt as part of the job, our deadbolt installation page explains what that involves.

Apartment lock replacement is common when a tenant moves in or out, when a key goes missing, or when a lock has been damaged. Business lock replacement covers storefront doors, back doors, office suites, and utility rooms. A business security upgrade might be as simple as moving from a basic knob lock to a sturdier deadbolt, or as involved as replacing a full set of commercial hardware. For anything beyond a single lock, our commercial door hardware page covers the heavier equipment.

  • Front, back, and side entry doors on houses
  • Deadbolts, knobs, levers, and combination sets
  • Apartment and condo entry doors
  • Storefront, office, and back-of-house doors
  • Locks that were damaged by a break-in attempt or a forced entry
  • Older hardware being swapped for modern, sturdier locks

How does a lock replacement visit work?

We keep the process simple and explain each step as it happens, so you are never guessing what is being done to your door.

  1. You call (213) 577-1366, any hour. We ask what the lock is doing, what kind of door it is, and whether the door is secure right now. If the situation is urgent, we tell you what to do in the meantime.
  2. We come to you in one of our mobile vans. We are a single company with a storefront in Westwood, not a dispatch service that hands your call to whoever is closest.
  3. We look at the lock and the door before touching anything. We check the cylinder, the bolt, the strike plate, the latch, and how the door sits in its frame. A lock that fails because the door has shifted will fail again if we only change the lock.
  4. We tell you what we found and what your options are: repair, rekey, or replace, and what each choice means for security and cost. If repair or rekeying will do the job, we say so.
  5. If replacement is the right call, we help you pick hardware that suits the door and how you use it. We then remove the old lock, fit the new one, and align the bolt and strike so it throws smoothly.
  6. We test the lock from both sides with the door open and closed, hand you the keys, and show you how it should feel. If anything is off, we fix it before we leave.

Should you replace the lock, rekey it, or repair it?

This is the question we would rather answer honestly than sell around. The three options solve different problems.

Rekeying changes the inside of a lock so old keys stop working and new keys take over. If the hardware is sound and your concern is who has keys, rekeying is usually the more economical route, and it keeps the look of the lock you already have. Repair makes sense when one part has failed, like a loose spindle or a sticking latch, and the rest of the lock is healthy. Our lock repair service covers those cases.

Replacement is the right answer when the lock is worn, damaged, weak for the door it protects, or simply not worth putting more money into. It is also right when you want a different type of lock, such as moving from a simple knob lock to a proper deadbolt. If you are weighing it up and cannot tell, describe the lock to us over the phone. We will give you a plain opinion, and we will not push a new lock when an adjustment would do.

What affects the cost of lock replacement in South Pasadena?

We do not quote numbers on a web page because the real cost depends on your door, not on a standard price list. Here is what moves it up or down, so you know what you are paying for when you hear a quote.

We explain the cost on the phone and again at the door before any work begins, so there are no surprises after the lock is already off.

  • Hardware grade. A basic lock and a high-security lock are very different products, with different materials, tolerances, and pick and drill resistance. Better hardware costs more and lasts longer.
  • Number of locks. Replacing one deadbolt is a smaller job than replacing every exterior lock on a house or a full set on a storefront.
  • Door condition. A door that is warped, poorly bored, or has a damaged edge may need some prep work before a new lock will sit and operate properly.
  • Type of lock. A standard deadbolt, a handle set, a mortise-style lock, a smart lock, and commercial hardware all involve different parts and different labor.
  • Keying. Having several locks keyed alike, or setting up a set of keys with a specific structure, adds some work.
  • Time of day. A call at an inconvenient hour is different from a scheduled daytime visit, and we are open 24/7 for both.
  • Distance. South Pasadena is roughly 20 miles from our Westwood base, and travel is a factor in any mobile service.

What does lock replacement look like in South Pasadena?

South Pasadena is a small, preservation-minded city, and its housing stock shapes almost every lock job here. In the Mission West district and across the Marengo neighborhood, many Craftsman, Victorian, and period-revival homes date from the 1890s to the 1930s, and plenty still carry original hardware. Vintage lockset repair and rekeying on Craftsman homes in Mission West is a typical call for us, and it often raises the replacement question: can we keep the original lock and make it work, or has it reached the end? When the old lock can be saved, we say so. When it cannot, we look for replacement hardware that suits the door and the house, rather than something that looks out of place on a period front door.

Climate plays a small part. The inland climate here is mild, moderated slightly by the Arroyo Seco, so weather-driven lock wear is modest. The one thing to watch is summer heat, which can swell older wood doors in historic homes. A door that rubs or sticks in July may be putting extra strain on the bolt and strike, and we check the fit before blaming the lock. When a lock here needs replacing, the cause is usually age, heavy use, or damage rather than weather.

Apartments and condos cluster near the Fair Oaks Avenue corridor and on Raymond Hill. Condo lockouts on Raymond Hill and apartment lockouts along Fair Oaks Avenue sometimes reveal a worn or damaged lock that needs replacing once the door is open. If you are locked out of a unit, our apartment lockout page explains how we get you in. The replacement is a separate decision, made once you are inside and we can look at the lock. In Altos de Monterey, the 1960s mid-century homes on the southwest hills often have original hardware that is now around sixty years old, and replacing front door and side door locks there tends to be a matter of wear rather than damage.

For businesses, storefront lock service on Mission Street near the Metro A Line station is a regular scenario. Storefront doors take constant use, so locks wear faster than on a house, and a business owner who finds a sticking or loose lock at closing time wants it handled quickly. We work across the 91030 ZIP code and the rest of South Pasadena, from homes near Garfield Park to shops along the Mission Street business district.

Is a security lock upgrade worth it, and what about business security?

Sometimes a replacement is also the moment to improve security. If a lock is already coming off, it costs little extra effort to put something stronger on. The question is how much strength you actually need.

For a house, the biggest improvement is often a solid deadbolt with a strong strike plate that is properly anchored into the frame. Many break-ins defeat the door frame rather than the lock, so the hardware around the lock matters. If you want more resistance to picking, drilling, and bumping, our high-security locks page covers what that hardware offers. If you prefer keyless entry, our smart lock installation service is a separate job, and we are upfront about which doors suit it and which do not.

For a business, a security upgrade usually means looking at the whole door: the lock, the latch, the hinges, the frame, and how the door closes. Replacing one lock on a poorly fitted storefront door may not improve much. We look at how the door really fails and recommend only what makes a practical difference. Commercial lock replacement also tends to involve keying decisions, such as who holds which keys, which we raise before the work starts.

Why call Wilshire Lock & Key for lock replacement?

We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties, including South Pasadena. We run a storefront at 10740 Wilshire Blvd in Westwood and send mobile service vans to you, so there is a real place behind the phone number.

When you call (213) 577-1366, you reach us directly, 24 hours a day, 7 days a week, all year. We are one company, not a dispatch middleman passing your job to a stranger who may or may not know the work. David, the owner and lead technician, oversees the work, and that matters on a job where the right answer depends on reading a door correctly.

What we offer is plain: we look first, we tell you what we found, and we recommend the lighter-cost option when it solves the problem. If you want to see where else we work, our locations page lists the areas we cover.

What should you ask any locksmith before they replace your lock?

Ask every locksmith the same questions, including us. 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 for it, and for the license number, before work begins. A real company will not mind.

Also ask whether the person who answers the phone is the person who will show up, whether the company has a physical address, and whether the quote you are given covers the whole job. Be wary of a very low quote on the phone that grows once the technician arrives. And ask what brand and grade of lock is being installed, so you know what you are paying for.

If you want to talk through a job before booking, reach out through our contact page or call (213) 577-1366.

Frequently asked questions

How long does it take to replace a front door lock?

A single lock on a door in good shape is usually a short visit. The time grows if the door needs adjustment, if there are several locks to change, or if the hardware is older and fits oddly. We look at the door first and tell you what to expect.

Can you replace a lock that is original to my Craftsman home in South Pasadena?

Often we can repair or rekey the original lock instead, and we will tell you if that is realistic. When replacement is needed, we look for hardware that suits the age and style of the door. We check each door individually, since older doors vary a lot in how they were made.

Do I need a new lock if I lost my keys?

Not always. If the lock is in good condition, rekeying it so the lost keys no longer work is usually the more economical route. If the lock is worn, damaged, or weak for the door, replacing it makes more sense. We help you decide based on what we see.

Can you replace a lock at night or on a weekend?

Yes. We answer the phone 24 hours a day, 7 days a week, all year. If a lock has been damaged and your door is not secure, call (213) 577-1366 and we will tell you how we can help and what to do until we arrive.

Will a new lock fit my existing door?

Most standard doors take standard locks, but we check the door's bore holes, thickness, and edge before choosing hardware. If the door has been drilled badly or has moved over time, we explain what needs to be done so the new lock works smoothly.

I rent an apartment near Fair Oaks Avenue. Can I have the lock replaced?

Check with your landlord or property manager first, since the lock is usually part of the unit and they may have rules about changes. If they approve, or if they ask us to do it, we replace apartment locks regularly. Landlords and property managers can contact us directly.

Do you handle business lock replacement for storefronts?

Yes. We replace locks on storefront doors, offices, and back doors, and we can look at the whole door if you want a business security upgrade. Commercial hardware differs from residential, so we match the lock to how heavily the door is used.

Should I replace all my exterior locks at once?

It depends. If you have just moved in, had keys go missing, or had a break-in, doing every exterior door at once is a sensible way to be sure of who has access. If only one lock is failing, you may only need that one replaced, and we will say so.

How do I know your company is legitimate?

Ask for the company's BSIS LCO license number, which California requires of locksmith companies, and check it yourself. You can also see that we have a physical storefront at 10740 Wilshire Blvd in Los Angeles and have been in business since 1987.
