How much does it cost to rekey a commercial building?
Rekeying a single commercial door lock typically costs between $50 and $150 per lock including labor, while rekeying an entire building depends heavily on the total number of locks and whether a master key system needs to be reconfigured at the same time. A master key system rekey generally costs more per lock than a standalone rekey, since it requires careful planning to maintain the intended hierarchy of which keys open which doors. Rekeying is significantly less expensive than replacing entire lock hardware, since it reuses the existing lock body and only changes the internal pins to work with a new key, making it the standard choice after a change in staff with key access.
When should a commercial building be rekeyed?
A commercial building should be rekeyed whenever there is reason to believe key control has been compromised, most commonly after an employee with key access leaves the company, especially in a role with access to sensitive areas, after a lost or stolen master key, or after a break-in where forced or unauthorized entry occurred. Some facilities also rekey on a set schedule, such as annually, as a general security practice regardless of specific incidents. Buildings that have gone through multiple staff changes without rekeying accumulate an increasing number of former employees who could technically still have a working key, which is a common and often overlooked security gap.
What is a commercial master key system and how does it work?
A commercial master key system is a hierarchy of keys designed so that individual keys open only their assigned door, while a master key higher in the hierarchy can open multiple doors, and a grand master key can open even more, often across an entire building or campus with multiple tenants. This allows different levels of access for different roles, such as a cleaning crew with a master key covering common areas while individual tenants retain keys that only open their own space. Designing a master key system correctly requires careful planning by an experienced locksmith, since a poorly designed system can accidentally allow a lower-level key to open more doors than intended.
Should a commercial building switch from keys to electronic access control?
Switching to electronic access control is generally worth considering for a commercial building with frequent staff turnover, multiple entry points needing different access schedules, or a need for an audit trail showing who entered a space and when, since electronic systems allow individual credentials to be deactivated instantly rather than requiring a physical rekey. Traditional keyed locks remain a reasonable and lower-cost choice for smaller buildings with stable staff and simpler access needs, since electronic systems carry higher upfront installation cost and ongoing software or subscription fees in many cases. A hybrid approach is a common way to balance cost against the benefits of electronic control.
How much does it cost to install commercial access control?
Commercial access control system cost varies widely based on the number of doors, whether the building has existing wiring that can be reused, and the sophistication of the software managing credentials, but a basic single-door card reader installation typically starts in the range of $1,000 to $2,500 including the reader, controller, and installation labor. Multi-door systems scale up from there, and systems requiring new wiring runs through finished walls generally cost more due to the added labor involved. Ongoing software or cloud subscription fees are common with modern access control systems and should be factored into the total cost of ownership rather than just the upfront installation price.
Why is my commercial electronic lock or keypad not working?
A commercial electronic lock or keypad that stops working is commonly caused by dead or low batteries in a standalone battery-powered lock, a lost connection to the access control network in a wired system, a firmware or software glitch requiring a reset, or physical damage to the keypad or reader itself from weather exposure or vandalism. Check battery level first on standalone units, since this is the most common and easiest cause to fix without a technician visit. For networked systems, check whether other doors on the same system are also affected, since a problem isolated to a single door points toward that specific lock, while a building-wide outage points toward the central controller.
Who is responsible for locks and keys in a multi-tenant commercial building?
In a multi-tenant commercial building, locks on doors within an individual tenant's leased space are generally the tenant's responsibility to maintain, while locks on common area doors, such as the main building entrance or shared restrooms, are typically the landlord's or property management's responsibility. Master key systems spanning the whole building are usually managed and controlled by the landlord or property management company, who typically retains a master key while individual tenants control their own unit-level keys. Building policy on rekeying, replacing lost keys, and who pays for these services should be spelled out in the lease.
