Home lock services for every Newmarket household

Your front door is the single most important security point in your home, yet most break-ins target weak, worn or poorly installed locks. We help Newmarket families keep that line strong — whether you live in an older home near Fairy Lake, a newer build off Yonge Street, or a rental closer to the GO Station. Every home is different, so we look at your actual doors and hardware before recommending anything.

We never push unnecessary upgrades. If a quick rekey or a simple adjustment solves the problem, that's what we'll suggest. When a real upgrade does make sense — a worn lock, a flimsy builder-grade deadbolt or a door that won't latch properly — we explain the options in plain language so you can choose what fits your budget and peace of mind.

Just moved in? Secure your home first

When you buy or rent a home, you have no idea how many copies of the keys are floating around — previous owners, their family, contractors, cleaners, real-estate agents and neighbours may all still have working keys. The fastest, most affordable way to take back control is to rekey or replace the exterior locks on day one.

We can rekey all your exterior doors to a single new key in one visit, so the old keys stop working immediately and you carry just one key for the whole house. It's one of the smartest, lowest-cost security moves a new Newmarket homeowner can make, and we do it every week.

Upgrades that actually improve security

A door is only as secure as its weakest part. We install Grade-1 and Grade-2 deadbolts, reinforce strike plates with longer screws that anchor into the door frame, and fit smart locks for keyless convenience. Small details — like the length of the screws in your strike plate — often make the difference between a door that resists a kick and one that doesn't.

We work with trusted, widely available brands so replacement parts and keys are easy to source in the future. If you want a keypad or smart lock so the kids never get locked out again, we'll recommend models that are proven, repairable and supported — not throwaway gadgets.

Locked out? We come to you fast

Home lockouts happen to everyone eventually. If you're stuck outside, call us and we'll reach most Newmarket addresses in 20–40 minutes and open your door using damage-free methods wherever possible. If your keys are lost rather than just locked inside, we can rekey on the spot so the missing keys can't be used to get back in.

Frequently Asked Questions

Should I rekey or replace my locks after moving in?

For most Newmarket homeowners, rekeying is the smarter first step. It changes the internal pins so all previous keys stop working, while keeping your existing hardware — which is faster and cheaper than full replacement. We'd only recommend replacing locks if they're worn, damaged, mismatched, or you want to upgrade the security grade or style. We'll look at your doors and tell you honestly which option makes sense.

How much does it cost to change locks on a house in Newmarket?

It depends on how many doors you have and the hardware you choose. Rekeying is typically the most affordable option at roughly $20–$30 per cylinder plus a service call, while installing new locks depends on the brand and grade you select. We always confirm the full price before starting so there are no surprises, and we can quote most jobs over the phone.

Can you make all my doors use the same key?

Yes. This is called keying alike, and it's one of our most popular requests. We can rekey or set up your exterior locks so a single key opens every door, which is far more convenient than juggling several keys. If you prefer, we can also set up a master-key arrangement for more complex needs.

Do you install smart locks and keypads?

Yes. We install and configure smart locks and keypad locks from reputable brands, so your household can enter without a physical key. We'll recommend proven models that are reliable, repairable and well-supported, and we'll set up the codes and walk you through using them before we leave.

Are you available for emergency home lockouts?

Absolutely. We provide 24/7 home lockout service across Newmarket, reaching most addresses in 20–40 minutes. We open your door using damage-free methods wherever possible, and if your keys are lost rather than locked inside, we can rekey on the spot for your security.
