    The order arrived in 14 days, threw it in a mailbox, wrapped in a poupock and an envelope. The keys are stitched into the system, there is no marriage. These keys are not flashing/duplicated, the number is sewed into them and the other cannot be sewed.

    Great deal for access fobs if you have a system that uses these. Register just fine on my programming system ‘Access Control’ and have about 6 in use so far, with apparently no issue.

    These work perfectly with our door system. I wanted an option for the female members, who have they’re keys in their hand, to scan and enter the building. The men are fine with the scan card.
