Stop carrying a different key for every door
If any of these describe what you're dealing with right now, this is the service you need. Call with your situation and location - we'll confirm we can help before sending anyone out.
Carrying a Different Key for Every Door
You manage 20 units and carry 20 keys. We set up one master key that opens every door in your building - maintenance calls take half the time.
Tenants Copying Keys Without Permission
Your tenants made copies at the hardware store and gave them to friends. We use restricted keyways where copies can only be made through you.
Tenant Moved Out but You Can't Rekey Everything
One tenant leaves and suddenly you're worried about every door. Our system lets you reset just that one unit without touching the rest of the building.
Maintenance Staff Needs Access to Common Areas Only
Your cleaning crew shouldn't open tenant units. We create sub-master keys that only open hallways, laundry rooms, and mechanical spaces.
Describe your situation - we'll confirm the right service and come prepared.

Tell Us About Your Building
How many doors? How many access levels (owner, manager, maintenance, tenants)? We map out who needs to open what before anything else.

Master Key Systems for Multi-Tenant Buildings in Delaware
If you manage an apartment building, office complex, or mixed-use property, you know the headache of tracking dozens of keys. Kwikey Locksmith designs master key systems that give you one key for every door while keeping each tenant restricted to their own space. We serve property managers across Delaware and nearby Pennsylvania who need simple, secure access management without going electronic.
How a Master Key System Saves You Money on Tenant Turnover
Every time a tenant moves out, you face a choice: rekey the whole building (expensive) or hope they returned all their keys (risky). A master key system eliminates this problem. We reset only the departing tenant's cylinder - your master key still works, other tenants aren't affected, and the cost is a fraction of a full rekey. For buildings with regular turnover, the system pays for itself within a year.
Restricted Keys That Can't Be Copied Without Your Permission
Standard keys can be duplicated at any hardware store for a few dollars. That means you never truly know how many copies of your building's keys exist. Our master key systems use restricted keyways - the blanks simply aren't available at retail locations. Every key copy goes through your authorization, giving you complete control over who has access to your property.

Do you work with insurance claims?
We provide written records of the work and hardware fitted on Wallingford jobs, which is generally what insurers ask for. Tell us in advance if you need particular detail.
Do I need to be present for the work in Wallingford?
For most jobs yes — we verify authority over the property or vehicle before starting. If that's difficult, call (302) 551-2550 and we'll work out what's practical.
What does master key systems cost in Wallingford?
It depends on the specifics, which is why we quote before starting rather than after finishing. Describe the job on the phone and you'll get a firm number to approve or decline.

Yes — labor and any hardware we supply are covered. If something isn't right after a Wallingford job, we return and put it right.

It won't, as long as the job matches what was described on the phone. If the technician finds something genuinely different in Wallingford, you'll be told and asked before any extra work happens.
Will the job be finished in one visit?
Usually, yes. Vans heading to Wallingford carry the common hardware and tooling, so most jobs complete on the first trip rather than needing a parts run.

Master Key Systems FAQ
These are the questions people ask most before booking this service. If yours isn't here, call us - we'll answer it directly.
Can you use my existing locks or do I need all new hardware?
In most cases, we can re-pin your existing commercial locks into a master key system. We'll check your hardware during the site visit and let you know if anything needs replacing.
What happens when a tenant moves out?
We reset just that unit's cylinder so the old tenant key no longer works. Your master key still opens everything, and no other tenants are affected. It takes about 15 minutes per door.
Can tenants copy their keys at a hardware store?
Not with restricted keyways. The key blanks we use aren't available at retail stores or kiosks. Tenants have to come through you to get copies, so you always know how many keys are out there.
How many levels of access can you set up?
As many as you need. A typical setup is: owner (opens everything), maintenance (common areas only), and individual tenant keys (their unit only). We can add more levels for larger buildings.
What if I add more units or doors later?
We design every system with expansion built in. Adding new doors to your existing master key is straightforward and doesn't require rekeying the rest of the building.
