Should Tenants Change the Locks?

A Practical Security Guide for Renters in Toronto, Etobicoke, Mississauga & the GTA.
Moving into a new rental home can be exciting – but it also raises an important question: who else might still have a key to your place? Previous tenants, cleaners, contractors, real estate agents, or even someone who found an old key may still have access.
For that reason, many renters across Toronto and the GTA choose to rekey or upgrade their locks as a standard security step. This guide explains why this is commonly recommended, what tenants should keep in mind regarding the rules, and how a professional locksmith service like Locksmith Express Toronto can help.
Before Changing Locks: Understand the Rules
Ontario’s Residential Tenancies Act contains specific rules about locks in rental units. The general principle is that both the tenant and the landlord must have access to the unit, and changes to the locks may require permission.
Because every rental situation is different, tenants should always check the exact legal requirements or review their rental agreement before making any changes.
If you’re unsure, the safest approach is to:
- Ask your landlord in writing before changing or rekeying locks
- Consult official Ontario resources or obtain legal advice if needed
This ensures full compliance and prevents misunderstandings.
Why Many Tenants Choose to Rekey or Upgrade Locks
Even with the best landlords and property management teams, security concerns are common when moving into a rental. Updating the locks is often considered a standard security practice, especially when:
- You’ve just moved in
You simply cannot know how many people had keys in the past. Rekeying allows only your new keys to work.
- A key has been lost
If a roommate, previous tenant, or anyone else misplaces a key, rekeying eliminates the risk of unauthorized access.
- The existing lock is worn or unreliable
Old or damaged hardware may be easier to pick or force open.
- You want more control over access
Sharing with roommates, subtenants, or frequent guests can make key management tricky.
- You want to upgrade overall home security
High-security cylinders, better deadbolts, or digital solutions improve peace of mind.
How to Upgrade Your Lock Security Responsibly
To keep things simple and avoid any legal issues, tenants can follow these steps:
1. Request permission in writing
Most landlords are reasonable as long as they continue to have access when required.
2. Choose the appropriate lock solution
Common options include:
- Rekeying the existing lock (quick, affordable, and usually recommended)
- Replacing old or weak deadbolts
- Upgrading to high-security cylinders
- Installing smart locks if the landlord approves
3. Use a professional locksmith
A qualified technician ensures that everything is installed properly, safely, and without damaging the property.
4. Provide a key
Depending on the rental agreement and provincial rules, landlords may need a copy of the new key.
The Most Popular Lock Options for Tenants
Different rental units may require different solutions:
Rekeying (Most common choice)
You keep the same hardware, but the key changes. Fast, cost-effective, and ideal for new tenants.
Deadbolt replacement
A must if the current lock is outdated, weak, or damaged.
High-security locks
Resistant to picking, drilling, and bumping – perfect for added protection.
Smart locks – Keyless entry
Convenient for renters who prefer digital access, temporary codes, or key-free living (requires landlord approval).
