Best Locks for Rental Properties Landlords Can Trust

A tenant moves out on Friday, the new lease starts Monday, and the keys have passed through more hands than anyone can confidently count. That is why choosing the best locks for rental properties is less about buying the most expensive hardware and more about building a reliable turnover process. A rental lock needs to protect the next tenant, stand up to daily use, and be practical for the person responsible for the property.

For single-family rentals, duplexes, apartment buildings, and small commercial units, the right answer depends on the door, the tenant profile, the local code requirements, and how often access needs change. A dependable locksmith can assess the existing doors and hardware before a turnover becomes an emergency.

Start With the Door, Not the Lock

A high-quality lock cannot compensate for a weak door frame, a loose strike plate, or a door that does not close properly. Before selecting new hardware, inspect the full opening: the door material, hinges, frame condition, latch alignment, and the screws securing the strike plate.

Exterior doors should have a properly fitted deadbolt and a reinforced strike plate secured with long screws that reach the framing behind the jamb. This simple detail makes forced entry significantly more difficult than relying on short screws driven only into trim.

For rental properties, look for residential deadbolts rated ANSI Grade 1 or Grade 2. Grade 1 is the stronger choice for high-traffic entrances, exposed locations, or properties with a history of attempted break-ins. Grade 2 deadbolts are often a sensible fit for standard residential rental doors when the door and frame are in good condition. Grade 3 hardware may cost less, but it is generally better reserved for low-security interior applications.

The Core Setup: Deadbolt and Passage or Keyed Lever

For most exterior rental doors, the most practical arrangement is a single-cylinder deadbolt paired with a separate lever or knob. The deadbolt provides the primary security, while the lower handle manages everyday entry and exit.

A single-cylinder deadbolt uses a key outside and a thumbturn inside. It allows occupants to leave quickly without a key, which is an important safety consideration. Double-cylinder deadbolts require a key on both sides and can create a dangerous delay during an emergency. They may also conflict with fire or building codes, particularly where a glass panel is near the lock. Always verify local requirements before considering one.

Choose a lever rather than a round knob when possible. Levers are easier to operate for tenants carrying groceries, using mobility aids, or managing children. They also tend to suit accessibility needs better. The lower handle does not need to be the highest security component when a separate deadbolt is installed, but it should be durable, correctly fitted, and matched to the door’s handing.

Rekeyable Locks Are Often the Best Value

A landlord should not need to replace a working lock every time a tenancy changes. Rekeying changes the key combination inside the existing lock cylinder, making old keys stop working while preserving the installed hardware.

This is usually the most cost-effective option when locks are good quality, in working order, and compatible with professional rekeying. It also gives property managers a clear security reset at every turnover. Rekey exterior locks whenever possession changes, after lost or unreturned keys, following a contractor dispute, or if there is any uncertainty about who may hold a copy.

Not every lock can be rekeyed, and not every rekeyable lock offers the same level of key control. Basic residential keyways are convenient, but keys can often be copied at many hardware counters. For a rental house with a limited number of keys and predictable tenants, that may be acceptable. For multi-unit properties or rentals with frequent maintenance access, restricted key systems deserve consideration.

When Restricted Keys Make Sense

Restricted keyways are designed so duplicates can only be made through authorized channels. They are particularly useful for property managers, small apartment buildings, commercial rentals, and properties where several staff members, cleaners, or contractors need controlled access.

The trade-off is cost and administration. Restricted systems require a clear record of who is authorized to request keys. That extra discipline is the point: it reduces the chance that a former employee, vendor, or tenant can quietly create unauthorized copies.

Smart Locks Can Simplify Turnovers, With Limits

Smart locks are increasingly popular in rental properties because they can eliminate physical key exchanges. A property manager can issue a temporary code for a new tenant, schedule a code for a cleaner, or remove access when work is complete. For short-term rentals and properties with frequent turnover, that convenience can be substantial.

However, smart locks are not automatically the best choice for every rental. Battery management, tenant support, Wi-Fi reliability, app permissions, and emergency access must all be planned before installation. A lock that works perfectly in a showroom can become a service call if batteries die, a tenant changes settings, or the property loses connectivity.

If you choose a smart lock, select a recognized brand with a physical key override, clear audit capabilities, and a straightforward method for resetting access between tenants. Keep the mechanical override key controlled, document administrator credentials, and establish who is responsible for battery replacement. Smart locks should make access easier to manage, not create confusion when a tenant is locked out at night.

For many long-term rentals, a quality mechanical deadbolt with a disciplined rekeying process remains the simpler and more dependable solution. Smart locks are best where the operational benefit clearly justifies the added management.

Do Not Forget Secondary Doors

Front-door security gets most of the attention, but rear doors, side entries, garage-to-home doors, patio doors, and basement entrances are frequent weak points. Every door that provides access to the rental should be included in the same security plan.

Sliding patio doors may need more than their factory latch. A properly installed auxiliary lock, security bar, or pin can limit lifting and forced opening. Garage entry doors should have the same deadbolt protection as the front door because an attached garage can offer cover from view. Basement doors should be checked for moisture damage, frame movement, and latch alignment before a new lock is installed.

Interior locking is different. Bedroom and bathroom privacy locks are appropriate where needed, but they should not be treated as security locks. Avoid installing keyed locks on interior doors unless there is a clear operational reason and local housing rules permit it. A tenant must be able to safely exit the unit without searching for a key.

Key Control Is a Security System, Not a Key Ring

The best hardware will not solve a key-control problem. Property owners should know how many keys exist, who has them, and when they were issued. That includes keys held by maintenance teams, leasing staff, cleaners, family members, and emergency contacts.

Keep a simple written or digital record for every exterior key. During turnover, collect keys, fobs, garage remotes, mailbox keys, and access cards before issuing new credentials. If any item is missing, rekey or reset the affected access point rather than assuming it will not be used.

For buildings with several units, consider a master key system designed by a qualified locksmith. A well-planned system can let authorized management access common areas and units while keeping one tenant’s key from opening another tenant’s door. Poorly planned master systems can become difficult to maintain, so this is not an area for improvised hardware-store solutions.

Common Rental Lock Mistakes

The lowest-cost lock is rarely the lowest-cost decision over time. Cheap hardware often wears out quickly, sticks in cold weather, or requires replacement after a few turnovers. Mismatched keyways can also leave a manager carrying several keys for one property, increasing mistakes during urgent calls.

Another common mistake is changing locks without correcting door alignment. If a deadbolt is forced into a misaligned strike, it can bind, fail prematurely, and leave tenants struggling to secure the door. Finally, do not rely on a tenant’s statement that all keys were returned. Rekeying is a routine security measure, not an accusation.

A Practical Standard for Every Turnover

Set one standard for exterior doors across the portfolio: quality Grade 1 or Grade 2 deadbolts, durable levers, reinforced strike plates, and a documented rekey or access-code reset before each new tenancy. Standardized hardware makes key management, repairs, and emergency service much easier.

For properties in Oshawa, Whitby, Ajax, Pickering, and throughout Durham Region, Durham Regional Locksmiths can inspect existing door hardware, rekey compatible locks, install new deadbolts, and help design restricted-key or master-key systems where they make sense.

A secure rental does not require the most complicated lock on the market. It requires hardware that fits the door, access procedures that fit the property, and a turnover routine that leaves no question about who can enter when the next tenant moves in.
