Kwikset Key Control Deadbolt - Key Management System Question

[Joe Norman]

Hello BP! I posted previously about key management systems, and I opted to go with the Kwikset Key Control Deadbolts. I love the concept of having one master Landlord key for all my front doors, while the tenants all have unique keys for each unit that can be easily rekeyed at turnover.

Here's the only problem I'm running into - copies of my master/landlord key don't work. Does anyone know if there is a special blank that has to be used for this cylinder? To my non-professional locksmith eyes the blanks all look the same but the copies of my master key aren't turning the lock. Copies of the tenant key do turn the tenant's cylinder which is makes it more confusing. Thanks in advance BP!
