How Preventive Lock Maintenance Can Help Reduce Property Maintenance Requests

Preventive lock maintenance can help property managers reduce avoidable maintenance tickets by catching worn keys, loose hardware, door alignment problems, sticking cylinders, and electronic lock issues before they interfere with resident access. Rather than waiting for a lock to stop working, property teams can incorporate locks and door hardware into scheduled inspections, unit turnovers, and preventive maintenance routines.

That approach aligns with broader multifamily maintenance guidance. The National Apartment Association (NAA) recommends systematic property inspections and continual preventive maintenance as core property-management practices. NAA's maintenance standards also emphasize scheduled service and follow-up inspections to preserve function and longevity while minimizing downtime and emergencies.

The Institute of Real Estate Management (IREM) similarly treats routine inspections, preventive maintenance, recordkeeping, and maintenance-program oversight as important property-management responsibilities.

For locks and door hardware, the practical takeaway is straightforward: don't wait for a resident lockout or failed door to discover that a component has been deteriorating for months.

"Many lock problems develop gradually. A key starts sticking, a deadbolt becomes harder to throw, or a handle begins to loosen. Adding those small warning signs to preventive maintenance inspections gives property teams an opportunity to address them before they become access problems." — KeyMe Locksmiths

Locks are easy to overlook because they're relatively small components compared with HVAC, plumbing, roofing, and other major building systems.

Operationally, however, they matter every day.

Residents, maintenance personnel, property staff, vendors, and other authorized users may operate doors repeatedly throughout the day. Every cycle places some degree of wear on keys, cylinders, latches, hinges, handles, closers, and related components.

Preventive maintenance is already an established principle in multifamily operations. NAA's Certified Apartment Manager framework calls for systematic physical inspections and preventive maintenance performed on a continual basis to preserve the property and reduce operating expenses. Its maintenance technician standards similarly describe scheduled service activities and follow-up inspections as ways to support component longevity and minimize downtime and emergencies.

IREM takes a similar approach. Its professional property-management standards include routine property inspections, preventive maintenance programs, operating procedures, and maintenance recordkeeping among the responsibilities involved in managing physical property.

Locks and doors can be incorporated into those existing processes rather than requiring an entirely separate maintenance program.

Reactive maintenance begins after someone experiences a problem.

With a lock, that might mean a resident reports:

• "My key won't turn."

• "The deadbolt is stuck."

• "My door won't latch."

• "The handle is loose."

• "My keypad isn't responding."

• "I can't get into my apartment."

At that point, an inconvenience has already become a maintenance ticket and potentially an urgent access issue.

NAA's guidance on preventive maintenance specifically recommends identifying systems where maintenance is needed and creating a process and schedule designed to address issues before they become larger problems.

IREM also emphasizes the value of proactive inspection. Its property-management guidance describes inspections as a way to understand the condition of an asset, maintain continuity of services, and make informed maintenance decisions rather than relying exclusively on reactive responses.

Applied to locks, that means noticing the deadbolt that has gradually become harder to operate before it stops working.

The Associated Locksmiths of America (ALOA) identifies several common problems that develop as locks and keys age.

These include worn keys, worn locks, and hardware that requires maintenance.

ALOA notes that locks wear as keys are repeatedly inserted and removed and that high-use locks can experience greater wear over time. It also identifies the latch as one component particularly susceptible to wear.

For property managers, common warning signs include:

• Keys becoming difficult to insert or remove
• Keys requiring additional force to turn
• Deadbolts rubbing or failing to extend smoothly
• Loose handles or lever hardware
• Latches sticking instead of retracting normally
• Doors that need to be pushed, pulled, or lifted to lock
• Visible key wear
• Intermittent smart lock operation
• Low-battery notifications
• Hardware that moves when it should remain firmly mounted

These aren't necessarily signs that the entire lock needs replacement. They are signals that the opening should be inspected.

One of the most useful maintenance distinctions is separating a lock-cylinder problem from a door-system problem.

A resident may report that the deadbolt no longer works smoothly, but the cylinder itself may be functioning correctly.

The actual cause could be:

• Loose hinges
• Door sag
• Strike plate misalignment
• Building movement
• Weather-related expansion or contraction
• Loose mounting hardware
• A latch no longer lining up with its strike

For example, if a deadbolt turns normally while the door is open but becomes difficult to operate when the door is closed, alignment deserves attention before the lock is automatically replaced.

This is why preventive inspections should evaluate the entire opening, not just the key cylinder.

Property managers don't necessarily need to create a standalone "lock inspection day."

Instead, add a short door-and-lock check to inspections already being performed.

NAA's apartment-management standards call for frequent and systematic property inspections, while IREM includes regular property inspections and preventive maintenance programs within professional property-management responsibilities.

During those inspections, teams can check:

• Does the door close normally?
• Does the latch engage without force?
• Does the deadbolt extend and retract smoothly?
• Is the strike plate properly aligned?
• Are handles and levers secure?
• Are hinges loose?
• Does the cylinder operate smoothly?
• Is there visible damage?
• Does the door closer function properly, where applicable?
• Are electronic locks responding normally?

A short inspection can identify developing conditions before they generate a resident request.

Keys themselves are consumable mechanical components.

ALOA specifically warns that keys show evidence of wear as they age and that poorly duplicated or worn keys can contribute to operational problems. It notes that in some situations creating a duplicate from a better original key can resolve an issue; when it cannot, a locksmith may need to diagnose the lock or originate the appropriate key.

Property teams should therefore watch for:

• Bent blades
• Rounded or heavily worn cuts
• Cracks
• Loose or damaged key heads
• Keys that work only when manipulated in a particular direction

A worn key shouldn't automatically be treated as evidence that the lock cylinder has failed.

When several residents or staff members use the same opening, comparing how different authorized keys operate can also help isolate whether the problem is associated with one key or with the lock itself.

There's another reason to address key wear early.

Creating another key from an already degraded key can reproduce imperfections rather than restore the intended original geometry.

ALOA specifically identifies worn or poorly duplicated keys as a common source of lock problems.

For property managers, this makes key condition part of key management, not merely an inconvenience for the resident.

When a key is visibly damaged or operating poorly, it should be evaluated before additional copies are made from it.

Unit turnover provides one of the best opportunities to inspect a residential door without creating an additional resident appointment.

NAA's apartment maintenance training treats make-ready inspections as a way to identify the work, materials, and contractor support required before the next resident moves in.

Locks should be part of that process.

During turnover, property teams can:

• Test every exterior lock.
• Evaluate whether rekeying is appropriate.
• Inspect resident keys.
• Tighten loose handles and hardware.
• Check door and strike alignment.
• Test deadbolts with the door open and closed.
• Verify mechanical backup keys for electronic locks.
• Test smart lock functions.
• Check battery status where applicable.
• Document hardware that may require future replacement.

Finding a sticking deadbolt during make-ready is far preferable to discovering it when a new resident returns home after move-in.

Electronic access doesn't eliminate lock maintenance. It changes what needs to be maintained.

A smart lock may combine:

• A mechanical cylinder
• A latch or deadbolt
• Batteries
• A keypad
• Wireless communication
• Electronic credentials
• Firmware or software
• Mechanical override components

That means both the mechanical and electronic sides of the system need attention.

Property teams should follow the hardware manufacturer's instructions for the specific system, which may include:

• Monitoring battery status
• Replacing batteries according to manufacturer guidance
• Testing keypad operation
• Verifying authorized credentials
• Confirming mechanical backup access
• Checking emergency procedures
• Applying manufacturer-supported firmware updates when appropriate

The objective is to identify a declining battery or intermittent component before it becomes a resident access problem.

Unit doors aren't the only openings that generate maintenance issues.

Multifamily properties may have heavily used doors at:

• Main entrances
• Leasing offices
• Package rooms
• Fitness centers
• Pool or amenity areas
• Maintenance rooms
• Storage areas
• Parking facilities
• Stairwells
• Other common spaces

Because these openings may experience substantially more cycles than an individual apartment door, wear can appear differently.

ALOA notes that high-use locks experience wear over time, reinforcing the value of monitoring frequently operated doors.

Depending on the property, common-area inspections may need to consider:

• Lever hardware
• Lock cylinders
• Latches
• Hinges
• Door closers
• Exit hardware
• Access-control components
• Strike alignment

Life-safety and code-regulated hardware should always be maintained and serviced according to applicable requirements and manufacturer instructions.

Preventive maintenance doesn't mean residents should stop reporting problems.

In fact, residents can provide valuable early warnings because they operate their doors every day.

Encourage residents to report symptoms such as:

• A key becoming harder to turn
• A latch beginning to stick
• A loose handle
• A door that suddenly requires additional force
• An electronic lock displaying a battery warning
• Intermittent keypad response

NAA's Certified Apartment Manager framework specifically includes monitoring service requests and conducting follow-up as part of improving resident satisfaction and property performance.

The goal isn't to eliminate every lock-related maintenance ticket. Some repairs will always be necessary.

The better goal is to prevent predictable failures and use incoming service requests to identify recurring patterns.

Maintenance records become more valuable when managers use them to identify patterns.

IREM's professional standards include maintaining property recordkeeping systems and monitoring maintenance programs. NAA has similarly emphasized the value of maintenance data for identifying conditions and directing management attention where it is most needed.

For locks and door hardware, consider recording:

• Date of repair
• Unit or door
• Reported symptom
• Diagnosis
• Repair performed
• Rekeying history
• Key replacement
• Hardware replacement
• Smart lock battery changes
• Repeat service requests
• Locksmith involvement

Over time, those records can answer useful operational questions.

Are the same doors generating repeated tickets?

Is one hardware type failing more frequently?

Are alignment problems concentrated in one building?

Are smart lock batteries being replaced reactively rather than through planned maintenance?

Those insights can inform future repair, replacement, and purchasing decisions.

Preventive maintenance doesn't mean repairing the same hardware indefinitely.

NAA's maintenance standards specifically include diagnosing whether products should be repaired or replaced, while IREM's property-management framework includes oversight of maintenance and capital replacement programs.

A single loose screw may justify a simple repair.

Repeated failures at the same opening may justify a broader evaluation.

Consider:

• Age of the hardware
• Frequency of use
• Repair history
• Availability of replacement components
• Compatibility with the property's key system
• Condition of the door and frame
• Whether failures are isolated or property-wide

Maintenance records help turn that decision from a guess into a documented operational choice.

Property maintenance teams can identify and address many routine hardware issues, but some situations call for locksmith expertise.

Examples include:

• Broken or malfunctioning cylinders
• Rekeying
• Keys broken inside locks
• Master key system problems
• Restricted key systems
• Recurring lock failures
• Commercial lock replacement
• Specialized door hardware
• Electronic lock troubleshooting within the locksmith's scope
• Situations where the underlying cause isn't clear

ALOA recommends qualified locksmith assistance when routine maintenance does not correct a worn or malfunctioning lock.

A locksmith can also help distinguish between a key problem, cylinder problem, hardware issue, or another condition affecting the opening.

The best approach is to make lock care part of the property's existing preventive maintenance system rather than creating a separate reactive process.

A practical program can include:

1. Inspect during scheduled property checks.
   Add basic lock, latch, handle, and door-alignment checks to existing inspection routines.
2. Test thoroughly during turnover.
   Evaluate every unit entry before the next resident takes possession.
3. Respond to early symptoms.
   Don't wait until a sticking key becomes a key that won't turn.
4. Monitor electronic locks.
   Follow manufacturer guidance for batteries, credentials, software, and backup access.
5. Track recurring issues.
   Use maintenance records to identify repeat failures and problematic hardware.
6. Make informed repair-versus-replacement decisions.
   Consider condition and service history rather than evaluating every ticket in isolation.
7. Use locksmith expertise where appropriate.
   Escalate specialized or recurring problems before they result in repeated access disruptions.

This reflects the broader approach recommended by NAA and IREM: systematic inspections, planned maintenance, documentation, and informed repair decisions rather than relying primarily on emergency response.

KeyMe Locksmiths connects property managers with locksmith professionals who can support residential and commercial properties with services that may include:

• Lock inspection and diagnosis
• Rekeying
• Lock repair
• Lock replacement
• Key duplication
• Master key system support
• Commercial lock and door hardware services
• Smart and electronic lock support where applicable
• Emergency locksmith assistance

For eligible, supported non-restricted keys, KeyMe's Online Key Copying also provides another duplication method: a user submits a photo of the key, the key is produced at a central facility, and the finished key is shipped to the requested address. Whether this option is appropriate for a managed property should depend on the key type and the property's authorization and key-control policies.

"The most useful maintenance program isn't the one that simply reacts fastest. It's the one that recognizes recurring warning signs, documents them, and addresses predictable problems before they repeatedly interrupt residents and staff." — KeyMe Locksmiths

The strongest reason to maintain locks proactively isn't simply to reduce the number of work orders. It's to keep an essential building function dependable.

NAA's multifamily maintenance standards emphasize systematic inspections, preventive maintenance, service-request monitoring, and informed repair decisions. IREM similarly incorporates inspection, maintenance planning, and recordkeeping into professional property management. ALOA's consumer guidance adds the locksmith-specific reality that locks, latches, and keys all experience wear through ordinary use.

Taken together, those sources support a practical strategy for multifamily operators: inspect access hardware before failure, pay attention to early warning signs, document recurring problems, and bring in qualified expertise when the issue exceeds routine property maintenance.

For residents, that can mean fewer unexpected access problems. For maintenance teams, it can mean fewer preventable urgent calls and better information about which hardware requires attention.
