What Our Locksmiths Handle

Clear breakdown of our lock repair, installation, rekeying, and commercial door hardware services.

01 / REPAIR
Lock Repair & Maintenance

Sticking cylinders, loose lever handles, and misaligned strike plates are common on busy doors. We diagnose the mechanical issue, replace worn internal components, and adjust the latch and strike so the door locks smoothly.

Jammed or spinning cylinders Mortise lock body servicing Latch & strike alignment Broken key removal
02 / INSTALLATION
Lock Installation & Upgrades

We install new locks on hollow metal, solid wood, and aluminum storefront doors. Whether replacing a damaged residential deadbolt or fitting Grade 1 commercial levers across an office floor, we prep the door properly and mount hardware built for daily traffic.

Grade 1 & Grade 2 lever locksets Commercial mortise locks Single & double cylinder deadbolts Aluminum storefront deadlatches & hookbolts
03 / REKEYING
Rekeying & Master Key Systems

When keys are lost, tenants move out, or employees leave, rekeying existing cylinders invalidates old keys without the cost of replacing the entire lockset. We also design and pin master key systems so building managers carry one master key while tenants access only their own space.

Commercial & residential rekeying Keyed-alike door groups Master & grand-master key systems Interchangeable core (SFIC / LFIC) pinning
04 / DOOR HARDWARE
Commercial Door Closers, Panic Bars & Hinges

A lock cannot secure a door that fails to close or latch. We replace leaking hydraulic door closers, install rim and vertical-rod panic exit devices, fit full-surface continuous hinges on heavy doors, and install latch protectors and kick plates.

Surface-mounted hydraulic door closers Panic exit bars & exterior trim Continuous geared & ball-bearing hinges Latch guards, astragals & flush bolts
05 / KEYLESS & STRIKES
Keypad Locks & Electric Strikes

For staff entrances, storage rooms, and shared corridors, we install mechanical pushbutton locks, standalone electronic keypad levers, and electric strikes compatible with intercom and card systems.

When the Door or Frame Also Needs Repair

Many lock failures are caused by a bent steel frame, rusted hinge pockets, or a damaged door slab. Because CSI Montreal INC. also operates a commercial renovation division, we can replace or reinforce damaged doors and frames on the same job.
