Commercial-Grade Lock Replacement in Waldau
A new tenant moved into the unit next door, and the property manager just found three different cylinders on three doors, none of them cut to the same key.
In plain words
Think of it as re-equipping a door for the job it actually does rather than swapping one lock for a similar one. A back door taking deliveries all shift needs different internals than a quiet office entrance, and a storefront's aluminum frame needs a narrow-stile lock a wood door was never built to accept. The locksmith matches lock body, cylinder and strike to the door's real prep and real use, decides with the business whether the new hardware joins an existing master key system or starts a new one, and leaves the opening cycling cleanly from both sides before the visit ends.
How the visit goesThe key to the office entrance turns with almost no resistance now, and some mornings the deadbolt does not fully retract until someone jiggles the handle and tries the key again.

How the visit goes


Reading the door before the lock
The door tells the locksmith what kind of hardware it can even accept. A hollow-metal or solid wood door with a mortise pocket cut into the edge takes a mortise lock body; an aluminum storefront door with a narrow stile takes a purpose-built narrow-stile lock or hookbolt; a standard cylindrical bore takes a heavy-duty lockset sized to that hole pattern. Handing, swing, backset and existing strike location are measured so the replacement drops into the prep that is already there rather than requiring the door itself to be re-cut.
Testing under real conditions before signing off
The finished hardware is cycled from both sides, under the door's normal swing and closing force, and by more than one person where staff are on site to try it, since a lock that operates cleanly for one hand may bind for another depending on height and grip. Any electric strike or reader tie-in is triggered several times to confirm consistent release. Only once the hardware performs the same way on repeated tries is the work considered finished rather than merely installed.
A record the next contractor can use
The business keeps a plain account of what was fitted: the hardware model and function, the keying it was cut to, how many keys were issued and to whom, and any fire or exit rating the door carries. For a property manager or facilities team, this record answers the next question about that door without another site visit, and for a business with several locations it becomes a reference for bringing other branches onto the same standard over time.

What affects the quote
Keying complexity
A single stand-alone cylinder is the simplest keying job. A master or grand-master structure spanning multiple doors, departments or locations takes more planning and more cylinders to combinate correctly, and that planning is part of the quote.
Site access and building type
A ground-floor storefront is the simplest case to reach and work on. A unit inside a larger building with its own access rules, or a site requiring coordination with building management, can add steps the quote takes into account.
Condition of the existing door and frame
A door and frame in good condition accept new hardware into the existing prep with little extra work. Damage from a break-in, a cracked frame or a previously mis-cut mortise pocket adds repair time the quote accounts for separately.
What to have ready
- What kind of door is it: solid, hollow-metal, wood, or aluminum storefront?
- Who can authorize the work and sign for new keys?
- What is currently installed: a knob, a deadbolt, a mortise lock, or an exit device?
Commercial-Grade Lock Replacement: questions
QuestionsWhat happens to keys held by former employees or contractors?
Once a cylinder is replaced or rekeyed, any key that was not reissued for the new combination simply stops working on that door. This is the direct answer to a key that walked out with someone who left the business, and it is worth doing across every door that key used to open, not only the one that prompted the call.
Does an electric strike need to match a specific lock function?
Yes. An electric strike has to suit the latch or deadlatch type it will receive, the door's handing and swing, and whether the application needs fail-safe or fail-secure operation, meaning whether the door should unlock or stay locked if power is lost. Choosing a strike without checking these against the mechanical lock is a common reason a door releases electronically but still binds mechanically.
Do you handle interchangeable-core (IC) cylinders?
Yes. An interchangeable-core cylinder lets an authorized key holder pull the core and swap in a new one when a key needs retiring, without removing the whole lock from the door. Businesses with regular staff turnover often move to this system because it turns a rekey into a short in-house task rather than a full service call every time.
