Cylinders & Keying

Interchangeable Cores

PDQ offers interchangeable cores in BEST® compatible Small Format (SFIC) and  Schlage® compatible Full Size, Large Format (LFIC).  Our highly skilled keying personal can design a keying system from a simple master key, to a complex system featuring, Master and Grand Master keys using the A2, A3 and A4 Systems. Along with designing new keying systems, PDQ can add to an existing system provided proper records are presented. In addition, PDQ offers both plastic and regular construction cores for use while work is in progress. This protects the integrity of the keying system while allowing use of the locks that are installed. The plastic construction cores are disposable, while standard construction cores can be returned for full credit.
