Home Rekey Service

When a property changes hands or a lease turns over, the physical locks rarely change. That means any key cut during the previous occupancy — whether it was handed to a dog walker, a neighbour, a contractor, or a family member — still works. Rekeying resets the internal pin configuration of your existing lock cylinder so that old keys become permanently useless and only your newly cut keys will operate the lock. It is faster, less disruptive, and far more thorough than simply adding a deadbolt, because it neutralizes every previously distributed copy at once.

For tenants, rekeying is especially important in older Mississauga rental stock, where high-turnover buildings along Burnhamthorpe Road or near Square One have often seen dozens of residents over the years. Ontario's Residential Tenancies Act permits tenants to change their own locks, but doing it correctly — without damaging the door frame or the hardware — requires the right tools and the right knowledge. Our mobile home rekey service is available around the clock at (289) 779-3062, so you can book us the day you pick up your keys rather than waiting weeks for a scheduled appointment.

A single residential property in Mississauga can have a surprisingly diverse mix of lock hardware. Our technicians are trained and experienced working with the full range, including mortise locks, which deserve special attention. A mortise lock — the kind recessed into a pocket cut into the door edge — is common on older Mississauga homes, century properties near Port Credit, and solid wood commercial-grade entry doors. These locks have a more complex cylinder and internal mechanism than a standard cylindrical lock, and rekeying them incorrectly can compromise the entire lockset. Our skilled team handles mortise lock rekeying with precision tools, keeping the multi-function body intact while swapping the pin tumblers to accept only your new keys.

Beyond mortise locks, we rekey Schlage and Kwikset cylindrical deadbolts, door knob locks, handlesets, padlocks with rekeyable cores, and sliding patio door locks. We also key locks alike across your property so that one key operates every exterior door — a practical upgrade that eliminates juggling multiple keys. If any lock is too worn or damaged to rekey safely, we will tell you honestly before we start work, recommend the right replacement hardware, and install it on the same visit wherever possible.

We know pricing transparency matters. Rather than quoting a flat rate that hides variables, Maple Guard Security gives you an exact, confirmed price before any work begins. Several factors shape that number: the number of locks being rekeyed, the lock type (a standard door knob lock takes less time to rekey than a high-security mortise lock with sidebar pins), the time of day you call (a 2 a.m. emergency locksmith callout involves different logistics than a mid-morning appointment), travel distance within the Mississauga service area, and whether any replacement parts — new cylinders, pins, keys — are needed. We talk through all of this with you on the phone so there are no surprises when we arrive.

What we do not do is pressure you into hardware upgrades you do not need or bundle services without explaining what each one covers. If rekeying your existing locks is the right solution, we will say so. If a lock is beyond rekeying and needs replacement, we will explain exactly why and show you the options. That straightforward approach is what keeps Mississauga residents calling us back and referring their neighbours.

Our goal on every home rekey service call is to leave your property exactly as we found it — except with locks that only you control. We use professional disassembly tools and follow manufacturer-recommended procedures to avoid marring door frames, scratching hardware finishes, or stressing cylinder housings. Damage-free service matters particularly with high-end mortise lock hardware, antique-style door knob locks, and decorative handlesets that would be expensive or difficult to source as replacements. Every technician on our team is insured, so you have peace of mind throughout the process.

Because Mississauga is a large city — stretching from the lakefront in Port Credit up through Meadowvale and across to Malton — a truly mobile locksmith has to be ready to travel. We are. Our dispatch team operates 24 hours a day, seven days a week, 365 days a year. Whether you are a new homeowner who just closed on a property near Cooksville GO Station or a tenant taking over a unit in Streetsville who wants the locks sorted before the moving truck arrives, call (289) 779-3062 and we will have a trained technician heading your way.
