The Short Answer: Upgrade Only If Turnover Is High

For most owner-occupied homes or stable rental units in Etobicoke and Lakeshore, is upgrading to mul-t-lock from schlage deadbolt worth it comes down to one metric: how many times per year do you rekey?

Rekeying needs can vary with tenant turnover and property access requirements. A professional locksmith can review whether your existing lock hardware is suitable. Rekeying and hardware work are priced per job.

If you manage rental property in Mississauga or Long Branch with annual turnover, Mul-T-Lock’s restricted-key system becomes valuable – only your master key works for rekeying, so emergency after-hours calls cost less because techs don’t have to call the previous tenant or manager to get authorization first.

The Full Answer: Five Factors That Change the Decision

1. Picking Resistance Matters – But Only in Specific Situations

Door hardware can have different security features and access considerations. A professional locksmith can assess existing locks and discuss appropriate replacement or upgrade options.

Mul-T-Lock’s engineering is genuinely different. The sidebar mechanism – a moving pin that has to align with a sidebar as the key turns – defeats the standard bump-key attack. It also resists picking much longer. But the difference only matters if you’re in a high-break-in neighborhood or managing a property that attracts opportunistic theft.

If you’re in New Toronto or Islington Village and have experienced break-ins, or if you’re renting units where previous tenants had sketchy connections, Mul-T-Lock justifies itself. If your property has good foot traffic, good lighting, and zero break-in history, Schlage (especially a quality residential version) is sufficient.

2. Master-Key Systems Are Cheaper With Schlage – But Restricted Keys Win With Mul-T-Lock

If you manage a multi unit building, a master key system may be worth discussing. A professional locksmith can review access requirements and door hardware. Work is priced per job.

Mul-T-Lock’s system costs about the same upfront, but here’s the advantage: Mul-T-Lock uses restricted keyways. Only a registered locksmith can duplicate a Mul-T-Lock key. A tenant can’t walk into a hardware store and get a backup made. That matters for properties with turnover, because it means you have absolute control over who has access.

Last year we recovered an Islington Village condo unit where the resident had lost both keys. The building’s restricted-key system meant the manager had to call us – a registered locksmith – instead of a tenant just getting a copy at Canadian Tire. We rekeyed it in 45 minutes. With Schlage, any locksmith could have done it, but so could the tenant’s friend who copies keys on the side.

3. Installation Complexity Can Double Your Real Costs

Deadbolt replacement options are priced per job. The exact price depends on the selected hardware and the condition of the door.

Some lock installations may require door or strike plate adjustments for proper alignment. A professional locksmith can assess the door conditions, and you get the exact price before any work starts.

For multiple units, the scope of lock installation and rekeying work can be reviewed before service begins. You get the exact price before any work starts.

4. Smart Locks May Be the Real Upgrade Path

Here’s something that surprises people: if you’re trying to decide between Schlage and Mul-T-Lock for a rental property, a smart lock like Schlage Encode or Yale Assure might solve your problem cheaper and better.

Smart lock options may offer digital access features for some properties. A professional locksmith can discuss compatible smart locks and door hardware. Installation is priced per job.

If your turnover is 2+ units per year, smart locks often cost less over 3 years than the Mul-T-Lock upfront investment. The downside: you need reliable WiFi or cellular, and some tenants resist “keyless” systems. But for landlords managing Mississauga or Lakeshore units where tech-savvy renters are common, this often wins.

5. Comparing Medeco, ASSA Abloy, and Other High-Security Options

If you’re already comparing Mul-T-Lock to Schlage, you might wonder: what about Medeco or ASSA Abloy? These are true high-security cylinders used in commercial and government buildings.

For residential or commercial property, lock hardware selection should reflect the building’s access needs and existing door hardware. A professional locksmith can discuss suitable options and provide the exact price before work begins.

Mul-T-Lock sits in the sweet spot: better security than Schlage, restricted-key control, and a price that makes sense for landlords with 3-10 properties. For anything larger, you might negotiate Medeco pricing.

When the Answer Is Different

You Already Rekeyed Everything Last Year

If you just invested in rekeying all your Schlage locks, don’t upgrade. The payback period starts now, and you won’t recover the Mul-T-Lock hardware cost for 3-5 years. Wait until natural replacement (a lock breaks, a door is replaced) to swap the cylinders.

Your Building Uses Kwikset or Master Lock

If you have older Kwikset or Master Lock cylinders, upgrading to Mul-T-Lock is a legitimate security improvement. These brands are even less pick-resistant than modern Schlage. But the upgrade cost is the same, so your ROI math doesn’t change – it just gets stronger if security is your primary goal.

You’re In an Area With Organized Rental-Housing Break-Ins

If you manage units in Mimico or near the Queensway and you’ve had break-ins (or you know neighbors who have), Mul-T-Lock becomes urgent, not optional. The cost is justified by insurance claims avoided and property damage prevented. Some landlords also see insurance premium reductions when they upgrade to high-security cylinders – ask your insurer for the specific discount percentage before deciding.

The Real Hidden Cost: Choosing the Wrong Locksmith

We see this mistake repeatedly in Etobicoke and Mississauga: property managers call the wrong vendors and get quoted prices that make no sense.

Mobile locksmith technicians can help with car key replacement and other automotive locksmith needs. The exact price is confirmed before any work starts.

The same principle applies to lock selection. Chain locksmiths and big-box installers often quote Schlage because it’s what they stock. They don’t mention Mul-T-Lock because it requires rekeying equipment and restricted-key certification they might not have. You’re not getting an unbiased recommendation – you’re getting what they can sell fastest.

If you call for a quote, ask these three questions: (1) “What brands do you install and why do you recommend each one?” (2) “What’s your cost for a master-key system with Schlage vs. Mul-T-Lock?” (3) “Can you show me the rekeying cost difference if we have three tenant turnovers per year?” A good locksmith will explain the tradeoffs. A vendor just pushing the cheapest option is not acting in your interest.
