About this service

Commercial locks take a beating. Constant use, rough handling, and sometimes forced entry attempts wear out hardware faster than residential use. We replace cylindrical locks, mortise locks, and storefront hardware on commercial doors. We carry Grade 1 commercial hardware from brands like Sargent, Corbin Russwin, and Schlage commercial lines, and we install with proper door prep to ensure smooth operation and long service life.

Grade 1 commercial hardware for heavy use
Proper installation with door prep

Residential Locksmith

Locked out of your home, need a lock rekeyed, or want a smart lock installed? Our residential locksmiths handle lockouts, rekeying, lock replacement and repair, deadbolts, smart locks, and gate locks.

Lock Rekeying

Change who can open your lock without replacing the hardware. Rekeying is fast, affordable, and the smart move when you move or lose a key.

Lock Replacement

Old, damaged, or low-quality locks put your home at risk. We replace residential locks with properly installed hardware that actually works.

Common Causes of Commercial Lock Replacement

Heavy daily use wearing out cylinders faster than residential hardware

A commercial entry door can be used hundreds of times a day, which wears components down far faster than a home door ever would.

A forced entry attempt

Attempted break-ins on storefronts or offices often damage the lock mechanism even when the attempt itself failed.

Outdated hardware that no longer meets security needs

Older mortise or cylindrical locks installed decades ago may no longer meet a business's current security expectations.

Door hardware upgrade during a remodel

Storefront renovations or office buildouts commonly include a hardware refresh to match new doors or a rebranded entrance.

Incompatibility with a new door closer or panic device

Adding a door closer or panic bar sometimes requires the existing lock to be replaced with a compatible function.

Failed lock function after years of use

A lock that no longer latches consistently under a commercial door's daily use load is a common replacement trigger.

A change in the door's function requirement

Converting a storage-function door to an entry-function lock, or vice versa, typically requires new hardware rather than a simple adjustment.

An ADA compliance update

Some hardware upgrades are prompted by accessibility requirements around how much force is needed to operate a lock or lever.

A tenant buildout in a leased commercial space

New tenants moving into a leased suite often replace existing lock hardware as part of their buildout rather than inheriting the prior tenant's setup.

The Risks of DIY Commercial Lock Replacement

Commercial hardware has different door prep than residential locks

Mortise locks in particular require door prep that most in-house maintenance staff haven't worked with before.

Compatibility issues with door closers or panic hardware

A mismatched lock function can prevent the door from working correctly with an existing closer or exit device.

Improper fire-rating compliance

Commercial doors are often fire-rated, and installing non-compliant hardware can violate code requirements.

Downtime for the business while troubleshooting

An improperly installed commercial lock can leave a door non-functional during business hours, which is a direct cost.

Latch function mismatch with the door's use case

Selecting the wrong lock function (entry, storeroom, or classroom function) can leave a door either less secure or less convenient than intended.

Door alignment overlooked during hardware swap

Replacing the lock without checking overall door alignment can leave latching issues in place even with new hardware.

Overlooking lock function codes (entry, storeroom, classroom, communicating)

Commercial lock functions have specific names tied to how they should operate, and ordering the wrong function can leave a door that locks or unlocks incorrectly for its intended use.

Reusing worn or incompatible strike plates

Keeping an old strike plate that doesn't match the new lock's throw distance can prevent the bolt from seating properly.

Not accounting for ADA-required operating force

Some jurisdictions cap how much force a lever or lock can require to operate, and a non-compliant replacement can create a code violation.
