Master Key Systems in Kent & Sussex County, DE

A commercial customer usually contacts us when key control has become confusing or risky. They often describe multiple keys floating around a building, subtenants with their own copies, or a need for cleaners and contractors to have restricted access. The sites are offices, small warehouses, medical suites, and retail storefronts in Kent and Sussex County where doors have different types of hardware. We see a mix of cylindrical deadbolts, mortise locks, rim exit devices, and padlocks on gates. Some facilities have existing master keying built on older pin-tumbler cylinders like Schlage C or Kwikset, while others have higher security cores such as Medeco or ASSA. The common element is a desire to reduce the number of keys while controlling who can enter which areas.

On site we start by mapping the desired access levels with the facility manager and any stakeholders who need input. We inspect each door and lock cylinder, noting brand, keyway, and whether there are master pins or a restricted key system. If the existing hardware can be rekeyed, we remove the cylinder, change the pinning to the new key system, and record the cut codes. For installations requiring new cylinders or cores, we replace cylinders with compatible units and test operation on every door. We label keys and update the keying schedule. We keep all work in our van and perform the rekeying at the door or inside the van's workspace so there is no need to bring hardware to a shop.

The complexity of the job depends on the lock hardware, the door type, and how many unique access levels are required. A building with uniform Schlage or Yale cylindrical locks and a single hierarchy is straightforward to rekey into a simple master system. Jobs get awkward when there are mixed brands, restricted or patented key systems, electronic access panels, or old mortise locks that require special parts. Doors with exit devices, rim cylinders, or padlocks on gates add time because of unique core sizes. Vehicle fleet locks, like those on delivery vans or service trucks, use different keyways and must be handled separately. When restricted keys or factory-registered cores are involved, sourcing parts can affect the approach.

When we finish, the customer has a clear keying schedule and labeled keys that match the agreed access levels. We leave a record of cylinder serials, key cuts if applicable, and which doors correspond to each key level. Before we go, we test every door with each relevant key to ensure smooth operation, verify that exit devices latch correctly, and confirm that electronic locks respond if they are part of the system. We also brief the facility contact on how to control future key duplication and what to do if a key is lost. Our work is mobile, done from the van at the site, and we document the system so building access remains consistent.
