Change Locks After Buying a House in Ontario, Door by Door

How this works in Ontario

When you change locks after buying a house, you are really choosing among three different jobs, and the price and the result differ for each. Rekeying keeps your existing hardware and swaps the pins inside, so old keys stop working. Replacing the cylinder alone suits mortise locks and rim locks, where the lock body stays and the part your key enters is new. Replacing the whole lockset suits hardware that is loose, worn, mismatched or bargain-grade. We score each door on four things: its grade, its condition, how well it fits the door prep, and whether it matches the rest of the house. A solid Grade 1 or Grade 2 deadbolt in good shape earns a rekey. A rattling knobset from a builder's catalog earns a swap. In Ontario most houses end up with a mix, and that is fine. What matters is that each door gets the answer it actually needs, and that you see the reasoning before you approve anything.

Work included on a typical visit

• Front door deadbolt and handleset swaps. The front door is the one everybody sees, so its hardware matters twice: for security and for curb appeal. We replace worn deadbolts and loose handlesets with Grade 1 or Grade 2 sets that fit your existing bore holes, and match the finish to your house numbers, hinges and porch light.
• Rekeying the locks worth keeping. Rekeying costs less than new hardware and takes less time per door, so we use it wherever the lock has life left. Kwikset SmartKey cylinders can be changed with a working key and a small tool; without a working key we replace the cylinder. Schlage and most other brands are re-pinned at the door or in our van.
• Garage-to-house door and side doors. The door between garage and house often has the cheapest knob on the property, plus a gap people forget. We fit a proper deadbolt, check the frame for kick-in weakness, and replace or rekey the lock so the key matches your front door. Side doors get the same treatment.
• Strike plates, frames and hinges. Past owners leave marks on door frames: filled holes, split jambs, cracks from old break-ins. We inspect the jamb around every strike and recommend reinforcement when it's needed. For serious damage we say so honestly and suggest a carpenter before you spend money on a lock.
• Getting into a house that came with no keys. A lockout at a house you've just bought is stressful because the key problem is suddenly yours to solve. We'll get you in with the least damage, set up your own keys and give you a fresh start, ideally before the movers arrive.

What's different about Ontario

Homes built decades ago in Ontario often have mortise locks, brass knobs and lock sets that have outlived several owners. Those locks are worth saving when they're sound. We usually replace the cylinder, rekey and keep the lock body, then add a modern deadbolt where the door lacks one. If the hardware is worn or missing parts, we can match it or suggest a sympathetic modern set. The goal is a safe door that still looks right.

Commuters often close on a house in Ontario and move in around a tight work schedule. Early-morning and evening appointments help, and our day starts at 6:30 a.m. every day, running until 11:30 p.m. Book around your drive and your move date, not just a convenient window. If you leave before sunrise, a keypad or smart lock can make mornings easier, and a spare key with someone nearby covers the rest.

Inland heat is hard on door hardware. Metal expands, finishes fade, and a south-facing front door can reach temperatures that warp thin lock parts. When you change locks after buying a house in Ontario, we look at how exposed each door is and recommend finishes and brands that hold up to sun, such as durable PVD or powder-coated sets. Smart locks need extra thought, since heat shortens battery life. We suggest a keyed backup on every one.

Example situations

• For example, buyers in Ontario who want to change locks after buying a house close on a Friday afternoon and plan to move in over the weekend. We're open every day, so the sensible plan is to book Saturday morning from 6:30 a.m., before the moving truck shows up. Until then they keep the keys they were handed on their person, lock what they can, and avoid leaving the place empty overnight.
• A typical call: after replacing the front locks, a buyer notices the sliding patio door can be lifted off its track from outside. We'd inspect the track and rollers, add a secondary lock and an anti-lift block, and make sure the new keyed lock on the slider matches the front door key. The front door was the visible risk. The slider was the quiet one.
• Imagine a retired couple in a 55-plus community near Toyota Arena who bought from a family with grown children, so many keys may be floating around. They also want lever handles on every door because knobs tire their hands. We'd replace knobs with levers, rekey the exterior locks to one key, and keep the hardware easy to use for years.
• For example, a family buys a new-construction home near Graber Olive House. The builder's warranty team may still hold keys, and finish carpenters, painters and flooring crews all had access before closing. The hardware is builder-grade, with thin strikes and short screws. We'd confirm who retains keys, swap the entry deadbolts for sturdier ones, add proper strikes and rekey the remaining locks to a single key.

How the visit works

1. Call with your closing date and what you've been handed. Start the conversation before closing if you can. We can't change anything until the house is yours, but we can plan the visit, pencil in a time and tell you what paperwork to have in hand. Planning ahead avoids a scramble on closing day.
2. Show proof of purchase and possession. Bring a photo ID and one document that ties you to the address: the closing statement, the recorded deed, or a utility bill in your name. We compare names and addresses and keep the process quick and friendly. It takes a few minutes and protects everyone involved.
3. Walk every door and score the hardware. On the walk-through, we operate every lock, check the latch alignment, and look at the strike plates, hinges and frame. A lock that turns smoothly with the door closed is a candidate for rekeying. A lock that binds, rattles or sticks is a candidate for replacement.
4. Decide door by door: keep, rekey or replace. We lay out a better and a best path for the front door and a simpler plan for the others. Many owners choose a mix: a premium deadbolt up front, solid rekeys elsewhere. If you want to stage the work over several weeks, we help you put the doors in the right order.
5. Install, align and fit-check each lock. We install each lock to the manufacturer's spec, check the bolt throw into the strike, and test the latch with the door closed and under load. If the door sags or the strike is off, we fix the door first, because new hardware on a poorly fitted door fails early.
6. Test every key, hand over, and list what's still open. We test every key in every lock, with the door open and then closed. You get the keys, any keying cards or codes, and a short written list of the lock work done and what remains on your own to-do list.

How we quote the job

• How many doors move from rekey to replace. If every door is sound, the visit is mostly rekeying. If five are worn, the quote shifts toward new locksets. Either way we give you the choice door by door, and we tell you plainly which replacements are worth it and which are optional.
• Smart features and keypads. A basic smart deadbolt costs more than a standard one, and a model with Wi-Fi, a camera or a fingerprint reader costs more still. We help you decide whether the extras suit your family, and we install and set up the account so it works the first night.
• Keys, key control and matching. One key for every door means matching keyways and sometimes extra rekeying, which adds a little to the bill. A restricted keyway adds more, because the system needs paperwork, special blanks and a controlled copy process. We explain when it's worth it.

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.

Mistakes to avoid

• Hiding a spare under a rock or mat. Burglars look there first, and so do neighbors who help with deliveries. Give a spare to someone you trust, or use a keypad lock with temporary codes you can cancel. A spare with a neighbor you trust is safer than any hiding place.
• Forgetting the openings that don't use a key. Sliding doors, garage remotes, the alarm panel and smart home accounts keep the seller's settings until you clear them. A new deadbolt doesn't help if the slider lifts off its track. Walk the whole house with a list before you call it done.
• Assuming new construction is clean. Builders, subcontractors and warranty crews may hold keys, and some builders key a whole development to a master. Ask who retains keys and for how long, then change or rekey the exterior locks. Written confirmation from the builder settles it.

Advice before you book

• Photograph each exterior door and its hardware at the final walkthrough. A clear picture of the front lock, the garage-entry knob and the slider latch helps us plan the visit before we arrive and gives you a record of what you inherited in Ontario.
• Before you change locks after buying a house, read the possession clause in your purchase contract. It spells out when the home becomes yours to occupy, and that is when lock work can start. Until then, the seller, their agent and sometimes a rent-back agreement control access. Your agent can confirm the date in a short call.
• After the lock change, test every key on every door the next morning, in daylight. A key that sticks or a latch that catches shows up better after a night of settling. If anything's off, call us; we'd rather adjust it now than have you locked out later.
• Pick one brand for the exterior doors. Schlage and Kwikset use different keyways, so a mixed set can't share a single key. Staying with one maker keeps the household to a single key and makes future repairs simpler for any locksmith.
