Familiar Lock Change Issues We Solve

We've handled every reason a homeowner needs new locks. Here are the situations our clients call us about most often.

🏠

Just Moved Into a New Home

A new homeowner has no way to know how many key copies exist from previous owners, agents, or contractors. Leaving old locks in place means unknown people could still have access. We change every exterior lock and issue fresh keys before you move belongings in.

🔑

Lost or Stolen Keys

A missing key set creates real uncertainty about who might be able to get in. Waiting to see if the keys turn up leaves that risk open the whole time. We change or rekey the affected locks quickly to close the gap.

🔧

Key Sticks or Requires Wiggling

A key that needs extra force or wiggling to turn usually signals worn internal pins or a misaligned cylinder. Continuing to force it risks the key snapping off inside the lock. We diagnose whether a repair or full change solves the issue.

🚪

Front Door Lock Feels Loose

A deadbolt or knob that shifts when handled often means mounting screws have loosened or the strike plate has worn down from daily use. Left alone, this weakens the lock's actual security. We tighten, repair, or replace the hardware as needed.

🚨

Recovering From an Attempted Break-In

Tampered or damaged hardware after an attempted break-in often can't be trusted to function reliably even if it still turns. Continuing to rely on it leaves the home vulnerable to a repeat attempt. We replace the hardware promptly and can recommend a higher security grade.

🔁

Preparing a Rental Between Tenants

A previous tenant may still have a working key long after moving out, creating liability for the landlord. Skipping a lock change between tenants leaves that exposure open. We change locks efficiently to keep turnover on schedule.

🛡️

Outdated or Low Security Grade Hardware

Older homes often still have Grade 3 hardware on a main entry point, which offers far less resistance to forced entry than modern options. Homeowners aren't always aware their front door is the weak point. We recommend and install an appropriate security grade upgrade.

🗝️

Locks Don't Match Across Multiple Doors

Carrying separate keys for the front, back, and side doors is a daily inconvenience most homeowners don't realize can be fixed. Rekeying every lock to a single key simplifies this without replacing all the hardware. We rekey multiple doors to work with one key in a single visit.

❓

Not Sure If Repair or Full Change Makes Sense

Homeowners often can't tell whether a sticking lock needs a quick repair or full replacement. Guessing wrong means either overpaying or delaying a fix that's genuinely needed. We diagnose the actual cause and recommend the appropriate option honestly.

What Customers Say About the Work

Natalie P.

Changed all our locks after closing

We had every exterior lock changed the day after we got the keys to our new house. Prime Windows Toronto had all four doors done in under two hours and matched everything to one key. Genuinely relieved knowing the previous owners can't get back in.

Julian R.

Recommended rekeying instead of replacement

I called expecting to pay for brand new hardware but the technician suggested rekeying since our locks were still in great shape. Saved us money and the process took less than an hour. Prime Windows Toronto never tried to upsell us.

Camille D.

Great work, one door needed extra adjustment

Three of our four doors went smoothly but the front door needed some frame adjustment since it had shifted over the years. Took a bit longer than expected but the technician explained why before doing the extra work.

Marcus T.

Upgraded to Grade 1 hardware on the front door

After a break-in attempt on our street, we wanted the highest security grade available for our front door. The technician from Prime Windows Toronto explained the grading system clearly and we ended up with a much sturdier deadbolt.

Deborah S.

Same-day response for a broken key

Our key snapped off in the lock on a Saturday morning. Prime Windows Toronto got someone out within a couple hours and had a new lock installed before lunch. Exactly the kind of fast response we needed.

Andre F.

Landlord who appreciates the thoroughness

I manage a few rental units and needed locks changed between tenants. The team was quick, professional, and gave me a clear invoice for each property. Makes my turnover process so much simpler.
