Home Rekey Service

Moving into a new home on Kortright Road, handing over keys after a tenant vacates a Stone Road rental, or realizing your house keys are gone after a busy week in the Hanlon Creek neighbourhood — these moments all share one thing: your current locks no longer fully belong to you. Rekeying is the smart, precise way to reclaim that control without replacing every lock on your door. At Maple Masters Locksmith Pros, our trained, insured technicians come directly to your Guelph address, mobile and fully equipped to rekey your locks on the spot.

A rekey service changes the internal pin configuration of your existing lock cylinder so that only brand-new keys will operate it. Every old copy — whether held by a former tenant, a previous owner, a lost roommate, or anyone else — becomes permanently useless. It is faster than a full lock replacement, preserves the hardware you already trust, and is confirmed with an exact up-front price before any work begins. Whether your home has traditional door knob locks, a heavy-duty mortise lock on a heritage door, or a mix of both, our team handles it all with precision and care.

Why Guelph Homeowners Choose a Home Rekey Service After a Move or Tenant Change — Maple Masters Locksmith Pros

Why Guelph Homeowners Choose a Home Rekey Service After a Move or Tenant Change

When you take possession of a resale property in Guelph — whether it is a Victorian semi-detached near the Downtown core or a newer build in Clairfields — you genuinely cannot know how many key copies the previous owners distributed over the years. Real estate agents, contractors, house-sitters, relatives: each could still have a working copy. Rekeying immediately after closing is the fastest way to make certain that your family is the only one with access. The same logic applies to landlords managing rental units along Edinburgh Road South or near the University of Guelph campus: between every tenancy, a professional rekey eliminates the risk of an unreturned key without the cost of sourcing entirely new locksets.

Tenant turnover situations often involve locks that have been handled repeatedly and may show wear on the keyway. Our technicians inspect each cylinder during the rekey process and flag any components that need attention — something a simple key swap at a hardware counter cannot do. We work with the most common residential lock formats in Guelph homes: standard pin-tumbler door knob locks, deadbolts, and the larger mortise lock assemblies found on older doors throughout the Exhibition Park and Ward neighbourhoods. If a cylinder is beyond rekeying, we advise you honestly and quote a replacement before touching anything.

Mortise Lock Rekeying and Specialty Hardware — Handled with the Right Tools

The mortise lock is a hallmark of Guelph's older housing stock. Unlike a standard cylindrical lock, a mortise lock sits inside a pocket cut into the door edge and combines the latch, deadbolt, and sometimes a nightlatch into one substantial assembly. Rekeying a mortise lock requires removing the cylinder from that assembly without damaging the surrounding door material — a process that demands the correct follower tools, plug followers, and pinning mats, all of which our mobile units carry. Attempting this without the proper equipment risks cracking the cam, misaligning the tailpiece, or scratching a refinished heritage door.

We stock pinning kits compatible with the major residential lock brands commonly found in Guelph homes, including Schlage and Kwikset cylinders used in both mortise and standard door knob lock formats. After rekeying, we test each key through multiple full rotations under load before we consider the job complete. If you have a multi-point locking door or a European-style mortise profile cylinder, let our team know when you call — we confirm compatibility before dispatching so there are no surprises on arrival.

Lost Keys, Break-In Concerns, and Emergency Locksmith Response Around the Clock

A lost key is more than an inconvenience — it is an open question about where that key is and who might find it. If your keys went missing somewhere public, like the Stone Road Mall parking lot or along the Speed River trail, rekeying the same evening is a reasonable precaution rather than an overreaction. Maple Masters Locksmith Pros operates as a 24/7 emergency locksmith service across Guelph, meaning a trained technician can be at your address in the middle of the night, during a weekend, or on a holiday. We answer every call live — there is no voicemail during off-hours.

Following a break-in or attempted forced entry, the affected lock should be assessed by a professional before you rely on it again. Our technicians examine the cylinder, the strike plate, and the door frame for damage that might not be visible at a glance. Where the lock is structurally sound, a rekey restores security; where damage has compromised the mechanism, we recommend the right replacement and install it during the same visit. Call (548) 490-6124 any time — we answer 24/7 and dispatch quickly throughout the Guelph area.

What Determines Your Rekey Quote — Transparent Pricing, No Surprises

Every rekey job at Maple Masters Locksmith Pros starts with a clear, confirmed price before any work begins. Several factors shape that final number: the type and brand of lock being rekeyed (a basic door knob lock cylinder differs in complexity from a full mortise lock assembly), the number of locks included in the service, whether new keys need to be cut and how many copies are required, the time of day the work is requested, and travel distance to your Guelph address. There is no hidden after-hours surcharge that only appears on the invoice — if the time of day affects the price, we tell you before we arrive.

We also serve commercial properties throughout Guelph, and a commercial locksmith rekey — covering office suites, storerooms, or multi-unit residential buildings — involves its own set of variables, including master-key system compatibility and the number of cylinders in the building. Regardless of the job size, the process is identical: quote confirmed, work completed, result tested, keys handed over. No work starts until you have agreed to the exact figure.

Frequently asked questions

Answers to what our customers ask most. Still unsure? Just call.

What is the difference between rekeying a lock and replacing it entirely?+

Rekeying changes only the internal pins inside your existing lock cylinder so that the old keys no longer work and new keys do. The hardware — the knob, lever, deadbolt body, or mortise lock casing — stays exactly as it is. Lock replacement means removing all of that hardware and installing new components. Rekeying is the right choice when your lock is in good working condition and you simply need to invalidate existing keys. Replacement makes more sense when the lock mechanism itself is damaged, worn beyond rekeying, or you want to upgrade to a higher-security grade. Our technician will assess your locks on arrival and clearly explain which option applies and why.

How long does a home rekey service typically take?+

For a standard residential property with two to four door knob or deadbolt cylinders, most rekeys are completed in under an hour once our technician is on site. A mortise lock rekey takes a little longer because the cylinder must be carefully extracted from and reseated within the door body, but it is still typically finished well within a single visit. If you have a larger property — a Guelph rental with multiple suites, for example — we will give you a realistic time estimate when you call. Because we are a fully mobile service, we arrive with all the tools and pinning stock needed for same-visit completion.

Can you rekey my locks to all work on one key?+

Yes. Keying multiple locks alike — so one key operates your front door, back door, garage entry, and any other exterior locks — is one of the most common requests we handle. It requires that the locks either already use compatible keyways or be reconfigured to share one. During our assessment we confirm which of your existing locks can be matched to a single key and advise on any that cannot due to keyway incompatibility. If a lock cannot be keyed alike, we let you know before proceeding. The result is a single key that works every matched lock, with extra copies cut on the spot.

I just moved into an older Guelph home with a large antique-style lock on the front door. Can that be rekeyed?+

Older Guelph homes — particularly those in heritage areas like Exhibition Park, The Ward, or St. George's Park — often have mortise lock assemblies that are decades old. Many of these can absolutely be rekeyed provided the cylinder is a standard pin-tumbler type. Our technicians are experienced with mortise lock hardware and carry the specialist tools required to remove and re-pin these cylinders without damaging the surrounding door or the antique escutcheon plate. In cases where the cylinder is a non-standard or warded type that cannot accept modern pins, we discuss compatible replacement cylinder options that fit the existing mortise pocket. We never force a solution that puts your door at risk.

Is it safe to call a locksmith late at night, and how do I verify the technician is legitimate?+

Maple Masters Locksmith Pros operates 24/7, and our technicians are trained, insured professionals who arrive in identifiable vehicles. When you call (548) 490-6124, you speak directly with our team — not a call centre — and we confirm the technician's estimated arrival and name before dispatch. On arrival, any legitimate locksmith should be willing to show identification and discuss the job before beginning. A key verification step we always follow: we confirm an exact price up front. If a technician you have called from any source refuses to give a firm price before starting work, that is a red flag. Our team will never begin work until you have agreed to the quoted amount.

Do you offer rekeying for rental properties with multiple units in Guelph?+

Absolutely. Tenant turnover rekeying for multi-unit residential buildings is a regular part of our work across Guelph. Whether you manage a duplex near the University of Guelph or a larger building off Woolwich Street, we can coordinate a rekey schedule that minimizes disruption between tenancies. For buildings that use a master-key system — where a landlord's master key must continue to work while tenant keys are changed — our team has the experience to rekey within that hierarchy without disrupting the rest of the system. Pricing for multi-unit jobs accounts for the number of cylinders, the lock types involved, and any master-key requirements, and is confirmed in full before work begins.
