Replacing the Locks on Your San Dimas House, Door by Door
Short answer: House lock replacement means swapping out the locks across a home, from the front and back doors to the garage entry, sliders and side gates, and keying the new hardware to a single key. In San Dimas, Julian's Locksmith walks the house with you, recommends which locks to replace and which only need rekeying, quotes the whole job, and installs it in one visit.

Some houses reach the point where every lock is tired at once. If your home still has the hardware it was built with in the 1970s or 1980s, the knobs probably wobble, the deadbolts grind and the brass has worn through to the base metal. Rekeying worn-out mechanisms just puts new keys into old problems. For a house lock replacement in San Dimas, Julian's Locksmith swaps tired hardware for sturdier sets that fit your existing door holes, reinforces the strikes on exterior doors and keys the whole house alike, so the job is done once and done right. We also check hinge screws and strike plates while the old locks are off, since a new lock in a loose frame only moves the weak point somewhere else.
How this works in San Dimas
A house lock replacement covers several families of hardware, and each opening needs its own kind. The front and back entries usually carry a bored deadbolt and a knob, lever or handleset. The door between the garage and the house typically gets a deadbolt and a latch too, and that door is usually expected to be solid or rated and to close by itself, so a lock swap shouldn't strip its closer or self-closing hinges. The garage side door often has the weakest lock on the property. Sliding glass doors use a narrow hook latch set into the door's stile, matched by screw-hole spacing. French doors may use flush bolts or a multipoint lock. Side gates need weather-resistant latches, and sheds use padlocks and hasps. Interior doors carry passage and privacy sets. We plan the house as a set, matching style and keying across all of it, while choosing the right mechanism for each opening rather than putting the same box on every door. Exact requirements vary by door and local rules, so we look before we promise.
How we can help in San Dimas
- Sorting each lock: replace, rekey or adjust. Not every lock in the house deserves the same answer. We sort them into three piles as we walk: replace what is worn, damaged, light-duty or the wrong style, rekey what still works well, and adjust what is sound but fighting a sagging door or a shifted strike.
- Exterior entry doors keyed alike. Exterior doors are the priority in any house lock replacement. We match each door's bore and backset, install Grade 1 or Grade 2 deadbolts, and set each strike so the bolt slides in easily. A door that needs a shove to lock gets adjusted first.
- Sliders, French doors and other back-of-house openings. Patio openings use their own hardware, not the bored locks found on entry doors. We match sliding hook latches by screw spacing, replace multipoint gearboxes on French doors when they stiffen, and key outside handles to the house where the door allows it.
- Smart lock up front, matched mechanical hardware elsewhere. Many households put a smart or keypad deadbolt on the front door or garage entry and keep standard locks elsewhere. During a house lock replacement, we install the smart lock, key its backup cylinder to the house key, and set codes for everyone who needs one.
- Reinforcing every exterior entry. Back doors and garage entry doors often have the lightest frames on the house. We replace thin strikes with heavy plates, run screws into the framing, check hinges for short screws, and replace them so the hinge side resists a kick as well as the lock side.
How San Dimas shapes the job
Hillside and foothill homes in San Dimas have long driveways, doors facing slopes and decks, and wildfire seasons that make quick, orderly exits essential. A house lock replacement should keep every exit usable from the inside without a key, pick finishes that tolerate wind-borne dust and ash, and secure the lower-level and deck doors that are easy to forget. We also check that gates and doors operate smoothly when you need to leave in a hurry.
Family houses in San Dimas accumulate keys the way they accumulate shoes: kids, grandparents, babysitters, neighbors. A whole-house lock replacement is a good moment to reset all of it. We key the exterior doors alike, put sturdy deadbolts on the garage entry and back door, fit privacy locks with outside releases on bedrooms and baths, and choose levers that small hands can use. Then we count the keys with you so you know exactly who has what.
Horse properties around San Dimas keep valuable tack, feed and equipment in barns and tack rooms that sit far from the house. A house lock replacement here should include those buildings, with sturdy hasps, weather-rated padlocks or keyed deadbolts and, where useful, one key shared with the house. Dust and moisture are hard on cheap hardware, so we choose parts that stand up to them and make gates easy to latch with gloves on.
Example situations
- A homeowner adds a pool and wants the back yard gate and the patio slider to be hard for small children to open. We fit a self-latching gate latch mounted high, replace the slider lock and add a high secondary latch, then key the gate to the house. Pool barrier rules are set locally, so we suggest confirming details with the building department.
- A homeowner rents a backyard casita and wants the tenant's key to open only the casita and the shared gate, never the main house. We replace the casita deadbolt, key the side gate to the casita key and rekey the main house to a different one. Two key systems, no overlap, and the owner carries both.
- After a parent passes, siblings inherit the family home in Lone Hill. Nobody knows how many keys exist, from neighbors to former caregivers. We inventory every lock, replace the failing 1980s hardware, rekey the sound deadbolts and hand the executor one key set and a written record. The house stays secure while the family decides what happens next.
- For example, a couple closing on a house near Horsethief Canyon Park and San Dimas Dog Park receives a ring of a dozen keys from the previous owner and no idea who else has copies. We walk the property, count eight locks including the side gate and the shed, replace the two worn knobs, rekey the good deadbolts and pin everything to one key. They move in with a single key and a short list of what's on each door.
How the visit works
- Tell us how many doors and why. The reason matters because it changes the plan. A move-in calls for fresh keys everywhere, a break-in puts the damaged entries first, and a remodel is about matching finishes. Tell us which applies, and we tailor the walk-through to it.
- Verify you live at or own the house. Our license is LCO7891 from the Bureau of Security and Investigative Services, and you can check it at search.dca.ca.gov. California's Locksmith Act is the law behind it. We ask for ID, confirm ownership or residency, and then begin the walk-through.
- Walk the property and build the plan. The plan is simple: a list of openings, what each needs and what hardware fits the existing holes. We choose one keyway for the house and one finish for the exterior doors, and we explain why, so the choices are yours and not ours.
- Approve one quote for the whole job. The quote shows replacements, rekeys, parts, reinforcement and labor in plain lines, so you can see where the total comes from. If you want to trim it, we can drop interior sets or keep a good lock, and the total changes accordingly.
- Work exterior first, then the rest. Where a door needs adjusting, we do it as part of this step: easing a strike, resetting a hinge, trimming a sticky edge. A lock that lines up with its strike lasts longer, and the doors close without the shove many owners have learned to live with.
- Key everything alike, test it and leave a record. Before we go we write down what is on each door: brand, model, finish and keyway. Keep the note in a drawer. It makes the next repair, a matching lock for an addition or a rekey after a tenant moves out much easier.
Pricing factors
- Grade, brand and style choices. Grade 1 locks use heavier parts than Grade 2 or 3 and cost more. A common approach is Grade 1 or 2 on exterior doors and simpler sets on interior closets. Brand and style vary too, from basic Kwikset and Schlage models to designer lever sets.
- Special openings: sliders, French doors and gates. A gate lock made for outdoor use costs more than an indoor lock bolted to a post, but it survives sun and rain. Slider and French door hardware varies from basic to heavy-duty. We explain which tier your openings actually need.
- Condition of the doors and frames across the house. We'll be honest if a door is beyond lock work. A rotted frame or warped slab needs a carpenter, not another lock. We note it on the quote, help you decide what to fix first and don't pile on work you don't need.
Every job gets a clear quote before any work starts. Call (951) 903-3193 with the details and we'll tell you what to expect for your situation in San Dimas.
Advice before you book
- Count the keys you have and the keys you suspect exist. Previous owners, former roommates, cleaners, contractors and relatives may all hold copies. If you can't account for them, replacing or rekeying all the exterior locks is the only way to be sure.
- Use levers on bedrooms and baths, especially with children or older relatives in the house. A lever with an outside emergency release opens quickly if someone gets locked in. Knobs also work, but levers are easier on hands and under stress.
- Keep the old locks until the new ones have been tested on every door. It lets you compare screws, latches and bores if something is off, and it spares you digging through the trash later. Once everything works, recycle the old hardware.
- Collect every old key after the job and take the useless ones out of circulation. A key that no longer fits any lock should not sit on a neighbor's hook as false reassurance. Hand out the new keys deliberately, and keep a count.
Mistakes to avoid
- Buying keyed-alike packs from different boxes. Each box shares its own key, but the next box doesn't. You end up with three or four keys again. Pick one keyway, rekey everything to match, and test every key in every lock.
- Spending on locks and ignoring frames. A Grade 1 deadbolt set into a thin jamb with short screws fails at the strike. Every exterior door needs a heavy strike plate and long screws into the stud, and the hinges need the same attention.
- Replacing every lock by default. A house lock replacement doesn't mean tossing hardware that still works. A sound Grade 1 deadbolt only needs new keys. Replace what's worn, damaged or weak, rekey the rest, and put the savings toward reinforcement or a better garage entry lock.

Frequently asked questions
What does a whole-house lock replacement cost?
It depends on the number of locks, how many are replaced versus rekeyed, the grade and finish, special openings like sliders and gates, the keying plan and any door repairs. We don't guess over the phone. After the walk-through you get one written quote for the whole house in San Dimas, and nothing starts until you approve it.
How long does a whole-house lock replacement take?
It depends on the door count and what each opening needs. A house with a few doors is a manageable single visit, while a larger property with gates and outbuildings takes longer. Reinforcement, door adjustments and unusual hardware add time. When you call, we ask the door count and give an honest estimate, and after the walk-through we confirm how long the work will take.
What happens to my old keys and locks?
Old keys stop working on every lock we rekey or replace, so they can be discarded. We return the old hardware if you ask and otherwise dispose of it. Keep the old locks until you have tested every door. We can cut spares of the new key, so everyone in the household ends up with a working copy.
Do I need to be home during the whole visit?
An adult who lives at or owns the house should be there at the start to verify ID, approve the quote and let us in. You don't have to watch every step, but you'll want to test the locks before we leave. If you can't be there, an owner or property manager can authorize the work by phone.
Can I do the work in phases?
Yes. Exterior doors go first because they protect the house, with everything keyed alike. Interior sets, gates and outbuildings can follow later on the same key plan. Phasing adds travel and means some doors keep their old hardware meanwhile, so if budget isn't the limit, one visit is simpler. We quote it both ways if you ask.
What if you find damage while you're working?
We stop and tell you. Rotted framing, split jambs or warped doors can't be fixed with a lock. We explain what we found, what it means for the new hardware and what the options are, including adding reinforcement ourselves or leaving that door for a carpenter. Nothing is added to the quote without your approval.
How far is San Dimas from your base?
San Dimas is about 34 miles from our San Bernardino base, roughly 37 minutes in light traffic. Arrival time depends on traffic and on the job the technician is finishing, so we give you an estimate on the phone before you commit.
