The Interactive patented key and key blank provide increased control over key cutting to achieve an even higher level of key security. Additional keys are cut after presentation of a Mul-T-Lock key card and verification of customer identity in accordance with Mul-T-Lock key cutting procedures, which may be obtained through professional Mul-T-Lock locksmiths. Interactive technology is retro-compatible with the Mul-T-Lock Classic system, allowing existing locks to be upgraded.
All keys have their unique serial number registered to owner of system.
