Residential Lock Replacement in Ontario: Choosing What Goes In
Short answer: Replace a home lock instead of repairing it when the housing is cracked, parts are discontinued, it was damaged in a break-in, or you want stronger hardware. For residential lock replacement in Ontario, Julian's Locksmith checks your door's bore and backset, recommends hardware that fits, and installs it on site. Call (951) 903-3193 for a quote.

Sometimes locks get replaced because the house changed, not because the locks failed. A new front door color, a kitchen remodel with matte black fixtures, or a move away from the polished brass of the 1990s can make old hardware look out of place. Changing finishes across a house involves more than the front door: back and side doors, interior passage sets, hinges and the screen door all show. We help plan a residential lock replacement in Ontario that keeps finish and style consistent, fits existing holes where possible and keys the exterior doors alike. Call (951) 903-3193 and we'll go over the options before anything is ordered.
How this works in Ontario
Residential lock replacement doesn't always mean replacing everything on a door. A typical exterior door has three separable parts: the knob or lever set, the deadbolt, and the strikes in the frame. Often only one of them has failed. A deadbolt with a cracked housing can be swapped while the matching knob stays. A worn but otherwise solid deadbolt may only need a new cylinder, including an upgraded or high-security cylinder that fits the existing body. A strike torn from the frame can be replaced with a heavy-duty version without touching the lock at all. Full replacement makes the most sense when several of those parts are worn at once, when the hardware comes from a discontinued line with no parts, when you want a higher security grade throughout, or when consistent style and keying across the house are part of the goal. We'll tell you which approach fits each door, because replacing a whole set to fix one failed component spends money on parts that still had years of life left in them.
How we can help in Ontario
- Knob and lever entry set replacement. Many homes still have the original builder knobs on the side and back doors long after the front got an upgrade. Replacing those with Grade 2 keyed levers or knobs in the same finish evens out security around the house. We key them to the front deadbolt during installation, so nobody is left carrying a separate key.
- Mortise lock replacement and conversion. Some homeowners upgrade from an old residential mortise set to a modern mortise entry lock with a deadbolt and a standard cylinder. That keeps the solid, single-unit construction mortise hardware is known for, while adding a stronger bolt and a cylinder that can be keyed to the rest of the house.
- Replacing a deadbolt with a smart or keypad lock. Replacing a keyed deadbolt with an electronic one is a good moment to reinforce the strike, since motorized bolts need clean alignment to work reliably. We also key the backup cylinder to match your other locks where the manufacturer allows it, so a dead battery never turns into a locked-out evening.
- Garage entry and side door locks. Some homeowners want the garage entry to be the keyless door, since kids and family usually come in that way. A keypad deadbolt or keypad lever there, with a backup cylinder keyed to match the rest of the house, removes the need for a hidden key under the mat while every door stays on one key.
- Keying the new locks. Replacement is the best time to get every exterior door on one key. We choose hardware that shares a keyway, such as Kwikset KW1 or Schlage SC1, and key each new lock to the same combination before installation. If you prefer to keep your current key, we can usually pin the new cylinders to match it.
What's different about Ontario
Newer homes usually have standard door prep, which makes swapping hardware easy, but they also come with builder-grade locks many owners upgrade early. A common residential lock replacement in newer Ontario tracts is trading the exterior builder hardware for Grade 1 deadbolts and Grade 2 levers, adding reinforced strikes and keying everything to a new key, since builders and subcontractors had access during construction.
Commuters want locks that work fast and need no thought at 5:30 in the morning. Popular replacements include a keypad deadbolt on the garage entry so you can lock up without keys, auto-lock settings, and front and back doors on one key. We can schedule a residential lock replacement early in the day, since we start at 6:30 a.m. every day, before you head out on SR-60.
Older homes in Ontario often have doors bored for hardware that no longer exists, mortise pockets, or several generations of patched holes. Residential lock replacement there starts with careful measuring and sometimes conversion plates or wood repair. We try to keep the door itself, since solid older doors are worth saving, and choose replacement hardware that fits the period look while adding a modern deadbolt.
Example situations
- For example, a house with daily sprinkler spray and hard afternoon sun on its back door has exterior locks with peeling finish and cylinders that corrode within a few years. The owners want hardware that lasts. We replace them with PVD-finish levers and deadbolts made for outdoor exposure, suggest moving the worst sprinkler head, and dry-lubricate the new cylinders before handing over keys.
- Picture an older homeowner whose arthritis makes round knobs and a stiff deadbolt a daily struggle. We replace the entry knob with a lever, swap the deadbolt for one with a larger thumb-turn, and suggest a keypad deadbolt on the garage entry so a code replaces fumbling with keys. Every keyed cylinder stays on one key, and the doors close with light pressure.
- In a 1930s Spanish-style house, for example, the front door's original mortise lock has a cracked case that can't be rebuilt, and no current mortise body matches the pocket. We fit a conversion plate that covers the old pocket, install a bored entry set and deadbolt in an oil-rubbed bronze finish that suits the house, and hand the original parts back to the owners.
- Picture a front door after an attempted break-in: the deadbolt cylinder was wrenched until the housing cracked, though the door held. The owners want stronger hardware. We remove the damaged deadbolt, install a Grade 1 model with a reinforced strike and long screws, add an edge wrap around the lock area, and rekey the other exterior locks so the whole house shares one new key.
How the visit works
- Inventory and goals. Some calls are simple: one broken deadbolt, replace it today. Others are whole-house projects with finish choices and smart locks. Either way, the first conversation sets expectations about which locks we carry, which need ordering, and whether you'd rather buy hardware yourself and have us install it.
- Measure the door prep. We also measure the frame. Strike location, jamb condition, the gap between door and frame, and whether screws can reach the wall framing all affect how the new lock performs. A new deadbolt installed into a weak or misaligned frame won't feel new for long.
- Choose the hardware. Choosing hardware means balancing security, ease of use and appearance. A Grade 1 deadbolt on the main entry, Grade 2 levers elsewhere, a keypad on the garage entry and matching finishes throughout is a common plan. We explain the options and leave the decision with you.
- Quote, approval and verification. You get an itemized quote: hardware for each door, labor, any strike or frame work, and keying. Nothing starts until you approve it. Because we're changing locks, we confirm you own the home or have the owner's authorization; tenants need written landlord approval unless state law gives them a specific right to change locks.
- Remove and install. Doors that need new holes get them drilled with proper jigs so the lock sits square. Old holes the new hardware doesn't cover are filled and can be finished. For smart locks, we also mount the interior unit, install batteries and pair the lock with your app before moving to the next door.
- Key, test and hand over. Before we leave, we walk through each door with you: how the locks work, how to change smart lock codes, which lubricant to use and when to tighten trim. Any door we noticed with problems beyond the lock, such as a sagging hinge or worn weatherstrip, gets mentioned too.
How we quote the job
- Hardware grade and brand. Within the same grade, prices vary with finish, style and features like SmartKey rekeying, pick-resistant cylinders or keypads. We quote hardware separately from labor, so you can compare options side by side and decide where an upgrade is actually worth it for your home.
- Fit and door preparation. If the new hardware fits the existing holes, installation is straightforward. Doors that need a new bore, a larger edge hole, a re-chiseled faceplate pocket or filled holes from old hardware take more time. Measuring first keeps those surprises to a minimum and lets us quote accurately from the start.
- Who supplies the hardware. You can buy locks yourself and pay only for installation, or have us supply them. Supplying your own can save on hardware, but returns and fit problems become your errand. When we supply the hardware, we're responsible for it fitting the door and keying correctly.
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 Ontario.
What to do before we arrive
- Before installing a smart lock, check your Wi-Fi signal at the front door and learn how your model handles a dead battery. Some use a backup key; others have external terminals for emergency power. Knowing the backup method before you need it can save you a lockout.
- If you're replacing a deadbolt next to a glass sidelight, think through egress before choosing a double-cylinder lock. A single-cylinder deadbolt combined with laminated glass or security film on the sidelight usually solves the reach-through concern without needing a key to get out in an emergency.
- Pick one keyway for the whole house before buying anything. If the front door is Schlage and the back door Kwikset, they can't share a key without changing one of them. Deciding up front lets every replacement lock run on the same key from day one.
- When replacing locks on a rental, choose hardware you can rekey quickly at turnover and deadbolts with at least a 13/16-inch throw, which is what California's rental deadbolt rule describes. Keep a key log for each unit, and if you manage several properties, consider keeping spare cylinders ready.
Common errors that cost time and money
- Replacing a lock on a door that's sagging or warped. The new lock inherits the old problem: a dragging bolt, a latch that misses, a keypad motor that strains. Fix hinge screws, strike position and door fit before or during the replacement, not after the new hardware starts failing.
- Reusing the old strike plate and short screws with a new deadbolt. The lock may be Grade 1, but if the strike is held by screws that only reach the soft jamb, a kick tears it out. Replace the strike and use screws that bite into the framing.
- Buying a lock before measuring the door. Backset, bore, thickness and faceplate shape all have to match, and a mismatch means new holes, a sloppy fit or a return trip. Measure first, or have a locksmith look before you buy, especially on older or custom doors.

Frequently asked questions
Can all my new locks work with one key?
Yes, as long as they share a keyway. Schlage and Kwikset, for example, use different keyways, so we choose hardware with compatible cylinders and key every new lock to the same combination during installation. Some decorative brands offer cylinders in common keyways, which lets premium hardware share a key with everything else. One key for the front, back, side and garage entry is the usual goal.
Can you replace a handleset without leaving holes?
Often. We measure your current handleset's mounting hole spacing and look for a replacement that matches it. When nothing in your preferred style lines up, the options include a backplate that covers the old marks or carefully filled and refinished holes. We show you those options before you choose, since the front door is the most visible place for a patch.
Can you replace my locks today?
Often, if the hardware you want is on the van and the doors fit standard prep. Specialty finishes, handlesets, mortise locks and multipoint mechanisms may need ordering. We work every day from 6:30 a.m. to 11:30 p.m. Call (951) 903-3193 and we'll tell you honestly what's possible in Ontario.
Is a double-cylinder deadbolt a good idea?
It's a tradeoff. A double-cylinder deadbolt needs a key on both sides, which stops someone reaching through nearby glass to turn a thumb-turn, but it also slows your exit in an emergency, and building codes generally expect the main exit to open from inside without a key. Many homeowners choose a single-cylinder deadbolt plus security film or laminated glass instead.
Will you install locks I bought myself?
Yes. We check the hardware against your door before starting and tell you if anything won't fit, such as the wrong backset or a handleset with different hole spacing. If the locks need keying alike, we can rekey them on site. When you supply the hardware, returns and product defects are handled through the store or the manufacturer.
Do you need proof that I own the house?
Yes. Before replacing locks, we confirm you own the home or are authorized to change its locks: photo ID with the address, a deed or tax bill, or a property manager's work order. Tenants generally need the landlord's written approval unless state law gives them a specific right to change the locks. These checks protect you from unauthorized lock changes.
How far is Ontario from your base?
Ontario is about 25 miles from our San Bernardino base, roughly 33 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.
