Covina, Los Angeles County
New House in Covina? A Locksmith Who Checks Every Entry Point
Short answer: Do the locks before the furniture. On the first evening, make sure every exterior door latches and locks and that nobody else holds the garage remote. Within the first week, have a locksmith check hardware, strikes and sliders. Julian's Locksmith serves Covina every day from 6:30 a.m. to 11:30 p.m. We're closed overnight, so plan move-in help around that.

A resale house has a past, and its hardware shows it. One owner swapped the front deadbolt for something sturdier and left a hollow knob on the garage entry. Another painted over a strike plate. A third added a keypad lock and never mentioned the code. When you buy in Covina, you inherit that patchwork. A locksmith for new house work sorts it into three piles: fine as it is, worth upgrading, and better replaced. Julian's Locksmith does that on site, quotes each pile separately, and leaves the decisions to you.
How this works in Covina
Resale houses in Covina come with older hardware and a history of partial fixes. The front door may have a solid Grade 1 deadbolt, while the side door still has a spring-latch knob that a credit card could slip. Cylinders wear until keys stick or turn too freely. Some homes run on two or three different brands because each owner replaced what annoyed them. A previous owner's keypad or smart lock may still hold a stranger's code. A locksmith walking the house sorts all of this into what is safe to keep, what is worth upgrading and what is better replaced. Often the most useful step is bringing the weak doors up to the level of the strong ones rather than replacing everything, which any locksmith for new house purchases should be willing to say out loud. That keeps spending proportional: a worn but sound deadbolt gets cleaned and kept, while a flimsy lock on the door everyone actually uses gets the attention.
How we can help in Covina
- Entry-point security walk-through. The walk-through ends with a ranked list in plain language: fix tonight, fix this month, nice to have. If you have an inspection report or a builder punch list, bring it. We'll match its door and lock items to what we actually find, and flag anything the report missed, such as a loose slider latch.
- Reinforcing strikes, hinges and door frames. A solid door is only as strong as what holds it. We check hinge screws, shim gaps behind the jamb, and fit door-edge guards or longer strikes where the frame is thin. For double doors and French doors we look at the flush bolts and the astragal too, because that is where they tend to give.
- Locks for the doors that came without them. Builders sometimes fit a deadbolt on the front door and a knob lock everywhere else. We add deadbolts to the side door, the garage entry and the back door, bored to the standard 2-1/8-inch hole and matched in finish, so every exterior door gets the same level of protection.
- Upgrading builder-grade hardware. Builder-grade locks do the job, but many sit at the lightest end of the range. We can step up to a Grade 2 deadbolt or, where a line offers it, Grade 1, from Schlage, Kwikset, Baldwin and others, with a heavier bolt, hardened insert and stronger strike. Upgrading the front, garage-entry and back doors usually gives the best return.
- A keying plan for the whole household. A new house is the best time to decide who gets which key. We can key every exterior door alike so you carry one, or separate the main house from a casita, workshop or rental unit. A short chart of doors and keyways keeps copies manageable as the household changes.
How Covina shapes the job
Buying an older home near Mesa Oaks usually means original hardware, shimmed jambs and doors planed and re-hung over decades. Our walk-through separates what is charming and sound from what is tired and risky. Old mortise locks can often be rebuilt instead of replaced, solid wood doors take reinforcement well, and a missing garage-entry deadbolt is a quick fix. We help you keep the character while closing the gaps.
Family homes in Covina need locks that work for a toddler's reach and a teenager's late return. We plan kid-safe interior privacy locks with emergency releases, keypads for teens who forget keys, and a spare-key plan that doesn't involve a rock by the door. A walk-through also catches slider latches small hands can open and gates that lead to pools or streets.
Commuters moving into a new house in Covina tend to leave before dawn and return after dark, so a front door that works smoothly in poor light matters. A keypad or smart lock spares you from fumbling with keys, and a lit entry makes the first look at the lock easier. We start at 6:30 a.m. every day, weekends included, which fits a visit before work.
Common situations
- Think of a hillside home near Vincent, where the lot is steep and the side gate leads straight to the backyard slider. The gate has a thumb latch and the slider has a flimsy factory hook. We'd fit a keyed gate latch, add a track bar and pin to the slider, and suggest lighting the side path.
- Imagine buyers who plan to rent the casita behind their new house in Covina. The main house should share one key; the casita needs another, with its own deadbolt and a keypad for guests. We'd set up a two-tier plan, keep a record of which doors share keys, and choose a restricted keyway so copies can't be cut without authorization.
- Take an owner who moves into a new house in August and finds the deadbolt hard to throw every afternoon, though it is smooth in the morning. Wood swells in heat, the frame has moved, and the bolt rubs the strike. We'd file or reposition the strike, adjust a hinge and lubricate, instead of replacing a lock that was never broken.
- Suppose a builder hands over a key set tagged permanent and mentions that crews used construction keys. Whether the temporary key stopped working at every door is worth testing, not assuming. We'd try a construction key in each cylinder if one is available, and rekey any door where the answer isn't clear. One door that still opens for a worker's key undermines the other five.
From your call to the finished job
- Tell us about the house. Call (951) 903-3193 and tell us whether the house is newly built or newly bought, how many exterior doors it has, and whether there's a slider, a garage entry or gates. Mention a move-in date or inspection list if you have one. That helps us bring the right hardware.
- Show that the house is yours. Before we work on a new house, we ask for proof it's yours: a closing statement, deed or purchase contract, plus a photo ID. For a new build, the builder's closing paperwork works. We do this for every home, because a locksmith who skips it is a risk to every homeowner.
- Walk every entry point together. Walking with you matters. You point out the door the dog uses, the one the kids slam, the slider that sticks. We show what we find in the lock and frame and explain why it matters, so the list we build at the end reflects your house and your routines.
- Sort the list: tonight, this month, later. Priorities depend on your house and budget. A weak door frame and an unlockable slider come first; a finish upgrade or a smart lock can wait. We explain our reasoning and take your preferences seriously, since you know how you'll live there and we know where the weak points are.
- Do the work while protecting new finishes. Most of the work happens in a single visit: strike reinforcement, new deadbolts, slider locks, opener resets and key cutting from the van. If a part has to be ordered, such as a particular finish or a high-security cylinder, we secure the door in the meantime and return to finish.
- Test, record and schedule the recheck. New houses settle, so we suggest a recheck at six to twelve months. A short visit then catches strikes that have drifted, doors that have started to rub and batteries that need replacing. It's optional, and it keeps small misalignments from becoming failed locks.
How we quote the job
- How many entry points and cylinders you have. Each door adds time: testing, reinforcing, rekeying or replacing the cylinder, cutting keys. Doing several in one visit is usually more efficient than scattering the work over weeks, since the drive and setup happen once. We'll tell you where batching saves money and where it doesn't.
- Grade, brand and finish of the hardware. Premium doesn't always mean better for you. A high-security cylinder with restricted keys makes sense for a rental or a large household; for a small family, a solid Grade 2 deadbolt properly reinforced may be the sensible spend. We'll tell you which we'd choose in your place.
- Door and frame condition. Steel and fiberglass doors need different handling from solid wood. Some can take additional bores and some can't without damage. We check the door type before quoting, so you don't pay for a deadbolt that a thin door can't hold.
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.
Common errors that cost time and money
- Assuming a new house is secure because everything is new. Builder-grade hardware and short screws are common, and construction workers had access for months. Treat the first week as a security setup, not a move-in detail you'll get to eventually, and have someone walk every door.
- Buying a handsome handleset without checking the door. A lock that doesn't match the backset, thickness or bore can wobble, bind or push the bolt off line. Measure before you shop, or let us check first, and avoid returns and extra holes that scar a brand-new door.
- Assuming construction keys stopped working. Some systems are designed to disable temporary keys the first time yours is used, but only if that happens at each door. Test each cylinder or ask for a rekey, so the only keys that work are the ones you hold.
Practical tips before you call
- Tell painters and flooring crews to keep paint and finish off strikes, hinges and cylinders. Paint in a latch makes a door stiff, and paint in a keyway can jam it. Ask them to remove the hardware or tape it off, and don't let anyone spray over a lock body. A clean install is easier for everyone.
- Hold off on a smart lock until your router is in its final spot. Stand at the front door with your phone and check the signal. If Wi-Fi is weak there, choose a Bluetooth or hub-based model instead. Whatever you pick, keep a keyed backup, because batteries have a talent for dying at inconvenient moments.
- On your first evening, test every exterior door with the door open and again with it closed. Turn the deadbolt and watch the bolt: it should slide fully into the strike without you lifting, pushing or pulling the door. If it drags or stops short, note which door and tell your locksmith. A half-engaged bolt protects far less than it seems to.
- If your garage opener came with several remotes, gather all of them and count. Erase the opener's memory with the learn button, then pair only the remotes you hold, and change the keypad code too. A forgotten remote in a builder's truck or a seller's drawer is as good as an unlocked door.

Not open around the clock, and we say so plainly. What we do offer is a long day: from 6:30 in the morning until 11:30 at night on Sundays, Mondays, Tuesdays, Wednesdays and Thursdays. Fridays and Saturdays get the same long day. That schedule covers the hours when people are usually heading out to work or getting back home.
ID locked inside with your keys? That's a common situation, and it isn't a dead end. We can open the door, and you show us your license or a piece of addressed mail from inside before we pack up. If nothing inside proves residence, your landlord or property manager can usually confirm it by phone.
Locked out in Covina?
Call (951) 903-3193 with the address and what's locked. You'll get an arrival estimate and a quote before anyone heads out, and when we arrive we'll ask for ID that ties you to the property. If a child or pet is shut inside a hot car or building, call 911 first.
Frequently asked questions
What does a locksmith do at a new house?
We check every way in: front, garage entry, back, side doors, sliders and gates. We test deadbolts, strikes, hinges and latches, fix or upgrade weak spots, set up keys and codes, and reset garage openers. You end up with a ranked list, finished work you approved and a one-page record. Call (951) 903-3193 and tell us whether the house is newly built or previously owned.
My builder says the locks are keyed to me only. Should I trust that?
It's worth testing. Some builders use construction keying, where the first use of your key is meant to disable the temporary one, but that works only if it happened at every door. If you have a construction key, or can borrow one, try it in each cylinder. Where the answer is unclear, a rekey settles it in one visit.
What proof of ownership do you need for a new build?
Photo ID plus something showing the house is yours: a closing statement, deed, purchase contract or the builder's sale and occupancy paperwork. If the house is in a trust or company name, bring the trust certificate or a confirmation from the owner of record. It's a few minutes of paperwork that protects your home and every other homeowner.
Can you add a deadbolt to the door from the garage into the house?
Often yes. These doors are commonly solid-core or fire-rated, so we follow the label and the rules, and we don't bore where a rating forbids it. We check the door and frame first, then fit a deadbolt and a reinforced strike with long screws if it's allowed. If the door is too thin or the rating limits it, we'll explain alternatives.
Will changing the hardware affect my builder warranty?
We can't speak for your warranty, so ask the builder's warranty representative before you swap anything. Many warranties focus on structure and systems rather than lock hardware, but terms vary. Keep the original parts and take photos before and after. If a lock or door is part of an open warranty item, let the builder handle that item first.
Do I need to upgrade every lock in the house?
No. Most houses need a few targeted fixes, not a full overhaul. We rank findings into tonight, this month and later, and quote each separately. The front, garage-entry and back doors, the slider and the gates usually come first. Finishes, smart locks and interior upgrades can follow. If you don't need something, we'll say so.
How far is Covina from your base?
Covina is about 39 miles from our San Bernardino base, roughly 45 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.
