What does a lock installation involve in Claremont?
Lock installation means putting new hardware on a door that has nothing on it, has the wrong kind of lock for how you use it, or needs an additional lock. A front door with only a knob and no deadbolt is the classic case. So is a freshly hung door, a door damaged in a break-in attempt, or a back entry that was never properly secured. It is different from fixing a lock that has stopped working, and different from changing the keys on a lock you already like.
The lock is only half of the job. The door has to be bored to the right size, the latch has to meet the strike in the frame, the backset has to match the hardware, and the door has to close without dragging. A good lock fitted badly will feel loose, stick in hot weather or fail to latch. We give the door and frame as much attention as the lock itself.
If your current lock works and you only want different keys, that is lock rekeying, a separate job. If the existing unit is worn out and you are swapping it for the same type, see our page on lock replacement. This page is about fitting new locks, including types your door has not had before.
Which types of locks do we install?
We fit hardware on residential and commercial doors. These are the installs people ask about most:
- Front door lock installation: a keyed entry set, a handle set paired with a separate deadbolt, or a lever with a deadbolt above it. We choose based on door thickness, existing bore holes and how your household actually uses the door.
- Door lock installation on side, rear and garage-access doors, which often get less attention than the front door but are used to get in just as often.
- Lever lock installation: levers replace round knobs and are easier on hands and wrists. They come in passage, privacy and keyed-entry functions, and we match the function to the room.
- Mortise lock installation: a mortise lock sits in a rectangular pocket cut into the door edge. It is common on older residential doors and many commercial doors. The pocket has to be the right size, so a mortise lock cannot simply be swapped for a cylindrical one without carpentry.
- Security lock installation: higher-grade deadbolts, reinforced strike plates, longer screws that reach the framing, and edge reinforcement where the wood is weak.
- Commercial lock installation: keyed entries, interior office locks and storefront hardware, covered in its own section below.

Call (213) 577-1366Where do deadbolts, smart locks and restricted keyways fit in?
Adding only a deadbolt is its own job, and we cover it on our deadbolt installation page. If you want keypad, app or fingerprint entry, that belongs on smart lock installation. And if your concern is key control, such as restricted keyways that make unauthorized copies harder, read about high-security locks before you choose hardware.
We mention these here because people often start by asking for a new lock and end up wanting something more specific. It is better to decide before we cut into the door than after.
How do we install a new lock, step by step?
Every door is a little different, but the process is consistent.
- You call (213) 577-1366 and describe the door, what is on it now and what you want. Tell us if the door is wood, metal or glass, and whether it is an exterior or interior door.
- We look at the door in person: thickness, material, edge condition, frame, existing holes and swing direction.
- We confirm the hardware with you before cutting anything. If your door needs a different lock than you planned, we say so and explain why.
- We prepare the door: boring or enlarging holes, mortising for the latch and strike, and repairing or reinforcing wood that is split or soft.
- We mount the lock, set the latch and fit the strike plate with screws long enough to reach the framing, not just the trim.
- We test with the door open, closed and latched, cycling the key, thumb-turn and handle repeatedly to make sure nothing binds.
- We hand over every key, show you how the lock operates, and tell you plainly if anything about the door or frame should be dealt with later.
What affects the cost of a new lock installation?
We do not put numbers on a web page, because the honest answer depends on the door in front of us. These are the things that move the cost:
- The lock itself: grade, finish, brand, and whether it is a basic cylindrical set, a handle set or a mortise lock.
- The door: a door already prepared for the hardware takes less work than one that needs new bores, a repaired edge or a custom mortise.
- Material and condition: solid wood, hollow-core, metal and glass doors are each handled differently, and a damaged frame adds work.
- How many doors, and whether you want the locks keyed alike so one key opens them all.
- Reinforcement: strike plates, edge plates and longer screws for doors that need to resist force.
- Timing and distance: a scheduled daytime job is different from an urgent after-hours call, and travel to Claremont is part of the picture.

Call (213) 577-1366How can you keep the cost reasonable?
Ask for the full scope up front: what is included, what could change once the door is open, and whether any carpentry is expected. The usually more economical route is a lock that suits the door you already have rather than one that forces extra woodwork. We will tell you when the lighter-cost option is a sound choice and when it is a false economy, such as fitting a strong lock into a door edge too weak to hold it.
How do Claremont's older homes change the installation?
Claremont's housing stock spans Victorian, craftsman and Spanish revival homes near the Village, notable mid-century tracts and custom homes, hillside houses in Claraboya, and faculty and student housing around the Claremont Colleges. That range means no two doors are alike, and standard hardware does not always fit.
Historic-district homes, such as those in the Russian Village District, often carry original or period hardware that owners prefer to preserve rather than replace. If that is your preference, we look for ways to add security without stripping the character: a modern deadbolt placed discreetly, a reinforced strike, or new hardware chosen to sit comfortably beside what is already there. Whether an existing mortise lock can stay and be supplemented depends on its condition and the door, and we assess that in person.
Mid-century and custom homes can bring their own questions, such as unusual door thicknesses, non-standard bore sizes or hardware that has been mixed over the years. We measure first and fit properly instead of forcing a lock to go where it was not designed to.
What does lock installation look like around the Village, the Colleges and the hillsides?
Claremont is covered by ZIP code 91711, but the work changes by area. In Claremont Village and Village West, older-home questions come up often, along with doors that face the public. Around the Claremont Colleges, faculty and student housing means many doors and many occupants, so a clear plan for which key opens what matters more than a fancy finish.
Off-campus student housing around the Colleges tends to produce rekey calls at turnover. A landlord who wants to add a lock where a door has none, or upgrade a tired entry set, is asking for installation instead, and that is work we do. Owners handling several units can read about our locksmith services for landlords.
In Claraboya and the North Claremont foothills, hillside home lockouts are a scenario we plan for. When we install a new front door lock on a hillside house, we talk through where a spare key will live and whether every exterior door should take the same key. If your home has several entries, it is worth setting that up while the hardware is being fitted.
The same process applies in Padua Hills, Towne Ranch, Arbol Verde and Pilgrim Place: look at the door, confirm the hardware, then fit it carefully.

Call (213) 577-1366Do Santa Ana winds and dry heat affect a new lock?
In practical ways, yes. Claremont's foothill position brings hot, dry summers and notably strong Santa Ana wind events. The two effects that matter for installation are heat expansion of wood doors and wind-driven debris. There is no marine-layer dampness here, so heat-driven movement is the bigger concern.
A wood door can expand in summer heat and shift slightly. If the latch and strike are set with no tolerance, the bolt can rub or the door can bind when temperatures climb. We leave sensible clearance and line the bolt up so it throws freely. Strong wind also slams doors, and a strike screwed into the framing tolerates that far better than one held by short screws.
Dust, grit and plant debris get into exposed keyways and latches during wind events. On exterior doors we pick hardware suited to the exposure, and we suggest a dry lubricant rather than oil, since oil tends to hold onto grit.
What about commercial lock installation for Claremont Village merchants?
Storefront and office lock service for Claremont Village merchants is a scenario we plan for. Commercial lock installation differs from residential work: doors are cycled far more often, some must allow quick exit, and several doors may need to work within one keying plan. We ask how each door is used before recommending hardware.
Typical commercial installs include:
- Keyed entry hardware, including mortise locks, on storefront and office doors.
- Lever locks on interior office, storage and restroom doors.
- Back-of-house and service door locks.
- Keying plans, such as keyed-alike sets, so staff carry fewer keys.
How does commercial installation connect to door hardware?
Closers, exit devices and full hardware sets are a larger category, which we cover on our commercial door hardware page. If your project is a single lock on a single door, we can usually handle it as straightforward lock installation.

Call (213) 577-1366How should you check any locksmith before they install?
California requires locksmith companies to hold a BSIS LCO license, issued by the state's Bureau of Security and Investigative Services. Ask any locksmith for it, including us, before work starts. Also ask who will actually come to your door, whether the company you called is the company doing the job, and what the quote covers.
Be wary of anyone who will not discuss scope until the door is already open, or who cannot explain why a particular lock suits your door. A reliable installer should be able to tell you what they are fitting, why, and what it depends on.
Frequently asked questions
Can you install a lock on a door that has never had one?
Yes. We bore the door for the lock and latch, fit the strike into the frame and test the result. The door's thickness, material and condition decide which lock suits it, and we confirm that in person before cutting.
What is the difference between lock installation and lock replacement?
Installation puts new hardware where there is none, adds a lock, or changes to a different type of lock. Replacement swaps out a worn or damaged lock for the same kind of unit. If you only want new keys on a lock that works, that is rekeying.
Can you fit a mortise lock in an older Claremont door?
Often, yes, but it depends on the door. A mortise lock needs a correctly sized pocket in the door edge, and older wood may need repair. If your door already has a mortise lock, we look at whether it can stay and be supplemented instead of replaced.
Will a new lock damage my historic door?
We try to keep cutting to the minimum. For period doors, such as those in the Russian Village District, we talk through options first, including adding a discreet deadbolt or reinforcing the strike so original hardware can stay.
Do I need a deadbolt on my front door?
Most people want one, because a spring latch alone is easier to defeat than a deadbolt held in a well-fitted strike. The right choice depends on your door and household, and we can walk you through it. Dedicated deadbolt work is covered separately on our deadbolt page.
Can you make several new locks use the same key?
Yes, keyed-alike sets are a common request for homes with multiple exterior doors and for small businesses. Tell us which doors should share a key when you call so we can plan the hardware.
How long does a lock installation take?
It depends on the door. A door already prepared for the hardware goes faster than one that needs new bores, a repaired edge or a custom mortise. Once we have seen the door, we can tell you what to expect for that job.
How much does lock installation cost in Claremont?
It depends on the lock, the condition and material of the door, how many doors are involved, any reinforcement needed, and the timing of the call. We will explain the scope and what could change it before we start work.
Should I buy the lock myself first?
Call us before you buy. Backset, door thickness, handing and the function you need all have to match, and a mismatch is a common reason for a lock that will not fit. We can tell you what to look for or help you choose.
Do you come to Claremont at night or on weekends?
Our phone is answered 24 hours a day, 7 days a week, year-round, and we serve Claremont and ZIP code 91711 with mobile vans. Call (213) 577-1366, describe the situation, and we will tell you what we can do and when.
