Common questions about costs and estimates for this service.
To estimate the cost for a commercial building, contractors should conduct a detailed site survey. Count every lock and cylinder that needs to be included in the system. Then multiply this number by the per-lock cost, which typically ranges from $15 to $35 in Stone Mountain, GA. Also, factor in service call fees, the complexity of the master key hierarchy, and any necessary hardware upgrades or repairs.
Yes, there are potential disadvantages. The primary concern is security: if a master key is lost or falls into the wrong hands, it can compromise the security of all locks it operates. "The higher the level of the lost master key, i.e., the grand master or great grand master key, the higher the security risk." Contractors should educate clients on robust key control policies to mitigate this risk.
Rekeying multiple doors into a master key system will involve a per-lock charge, typically between $15 and $35 per lock or cylinder in Stone Mountain, GA. Additionally, a service call fee (usually $50 to $100) will apply. For a full home with multiple locks, the total cost for rekeying can range from $100 to $200 when done during a single visit.
Contractors can save clients money by performing a comprehensive initial assessment to avoid rework, offering bundled pricing for multiple locks, and suggesting cost-effective lock types that still meet security requirements. Planning for future expansion during the initial design can also prevent more costly modifications later on.
A 'premium' master key system (priced $29–$35 per lock/cylinder) often involves higher security cylinders, more complex key hierarchies (e.g., grand master keys for different departments), patented keyways that prevent unauthorized duplication, and potentially more durable or specialized lock hardware. A 'basic' system ($15–$20) might be a simpler setup with standard cylinders and a less intricate keying structure for a single lock or cylinder.
