Covina, Los Angeles County
House Lock Replacement in Covina
Short answer: Most houses have more locks than owners remember: front door, back or patio door, the door from the garage into the house, the garage side door, a sliding door, side gates and sometimes a shed. A house lock replacement covers each one with hardware suited to that door, so the slider, gate and garage entry get as much attention as the front.

A whole-house lock job is easier than most people expect. You call (951) 903-3193 and tell us roughly how many doors are involved. We give you an honest arrival estimate, come to your house in Covina, verify ownership or residency, and walk every entry with you. You get one written quote. Once you approve it, we work door by door, exterior first, then key everything alike and test it. We work every day from 6:30 a.m. to 11:30 p.m., under California license LCO7891. Larger jobs, with gates or outbuildings, are best booked ahead so we can set aside enough time.
House Lock Replacement in Covina: what to expect
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.
Work included on a typical visit
- Sorting each lock: replace, rekey or adjust. This sorting step is where a whole-house job saves money. A Grade 1 deadbolt that is ten years old and still smooth only needs new keys, while a loose knob with a rattling latch needs to go. We explain the reasoning for each lock, and you make the final call.
- Exterior entry doors keyed alike. We replace the front, back and side door locks with matched deadbolts and knobs, levers or handlesets, all in the same keyway and finish. Each gets a reinforced strike with long screws, and all of them run on one new key when we're done.
- Interior passage and privacy sets to match. Privacy locks on bedrooms and bathrooms should have an emergency release on the outside, so a parent can open a door a small child locked. We install sets with that feature, set latches so doors close quietly, and fix loose hinges or misaligned strikes as we go.
- 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. Doors with past damage, such as split jambs or chewed edges from earlier locks, get reinforcement plates or wraps where the new lock mounts. We point out anything beyond lock work, like a rotted frame, so you can plan repairs.
What's different about Covina
Family houses in Covina 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.
Heat reshapes door hardware across Covina. West-facing doors swell and bind, plastic parts soften, lubricants dry out and keypad batteries lose life faster. A whole-house lock replacement is a good time to switch to metal-bodied sets, check door clearance and choose finishes that tolerate sun without peeling. We often find that the same two or three doors on the hot side of the house cause most of the complaints about sticky, stiff locks.
In commuter neighborhoods around Covina, houses sit empty for long stretches while everyone is on the road. That makes the quiet doors matter: the garage entry, the side gate and the back slider are all out of sight during the day. A house lock replacement should cover every entry, with keypad or smart options on the doors you use while rushing in and out, plus reliable mechanical backups. We plan the visit around your schedule and our 6:30 a.m. to 11:30 p.m. hours.
Common situations
- 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.
- 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.
- After a kitchen and bath remodel in Charter Oak, fresh paint makes the 1990s door hardware look dull. The homeowner asks for matching hardware on every door in the main hall and on the exterior. We fit levers, rekey the working deadbolts to match and finish with a hardware list so future touch-ups use the right brand and finish.
- A homeowner's former partner left with keys to the front door, the back door and the garage entry. Rekeying only the front door would have solved a third of the problem. We replace the garage entry lock, which was already loose, rekey the rest and test every key on every door. Only the new key opens anything now.
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. This step keeps whole-house jobs from getting messy. By the end of the walk-through you know the count, the condition and the recommended action for every lock. If a door is unusual, we tell you what we'd need to order before promising a one-visit finish.
- 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. Exterior doors come first, one at a time, so the house is never left open. We remove, fit, reinforce and test each lock before moving on, then handle gates, sliders and garage doors, and finally interior hardware if it is part of the job.
- Key everything alike, test it and leave a record. You test the locks yourself while we're still there. We show you how any smart lock works, which key fits the gates, and how to tell when a lock is starting to fail. If anything feels off, we correct it on the spot.
What affects the cost
- How many locks, and how many are replaced versus rekeyed. Each additional lock added to the same visit tends to cost less than a separate trip would, because we are already there with the tools and your approval. That is why planning the whole house in one trip is usually sensible.
- Keying plan and number of keys. Smart locks add a keying layer: the backup cylinder gets keyed to the house, and codes get set up. Restricted keyways, key cards and duplicated spares add up, so decide how many keys the household really needs before the visit.
- Condition of the doors and frames across the house. Older houses and past break-ins tend to hide more damage than the lock shows: chewed edges, short screws, flimsy strikes. Reinforcing every exterior entry adds modest cost per door, but it keeps the new lock from being the strongest part of a weak door.
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 Covina.
Practical tips before you call
- If you rent a room or a casita, give each living unit its own key system. A tenant key that opens the main house defeats the purpose of having separate spaces. Tell us the arrangement, and we'll plan keys that match it.
- 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.
- 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.
- 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.
Common errors that cost time and money
- Changing locks one door at a time over a long stretch. Meanwhile an old key still opens whichever doors haven't been done. If you must phase the work, do the exterior doors in one visit and rekey the rest to the same key right away.
- Fitting interior locks with no emergency release. Bedroom and bath privacy locks should open from outside with a pin or coin. A lock that needs a key from the hall, or one that jams, can trap a child. Choose proper privacy sets for every room that locks.
- Throwing away the old locks too soon. A bore that's off by a few millimeters, a missing screw or a latch of the wrong length is easier to sort out with the old hardware beside the new. Keep it until every door has been tested.

Frequently asked questions
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.
Should I replace the locks when I buy a house?
Yes, at least rekey them. You can't know who has copies, from previous owners to agents, contractors and neighbors. A house lock replacement at move-in also lets you swap worn hardware and fit one key to every exterior door. Many owners do it before moving boxes in. We verify ownership first, then rekey or replace and test everything.
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.
Do sliding doors and gates use the same key?
Not automatically. Sliding door latches are often unkeyed, though some keyed handles can join the house key. Gate locks and padlocks usually come with their own keys, but we can fit models that accept your house keyway where available. We list which locks can share your key, which can't and what the alternatives are before we quote.
I'm a landlord with a rental house. Is it the same process?
Largely, yes. We verify you own the property or manage it for the owner, walk the house and give one quote. California requires working deadbolts on main swinging entry doors, and Civil Code sections 1941.5 and 1941.6 set lock-change rules for landlords in certain protective order situations. Tell us if a tenant is in place so we can schedule around their access.
How far is Covina from your base?
