The Omnimed Manager Key and Programming Key (#291591) are required accessories for the non-audit E-Lock. The lock provides secure keyless entry for patients or clinicians and is equipped with a 1/2 inch dead bolt, usage and low battery indicators, a tamper guard and programmable automatic unlock. Each of the keys for this lock performs a different function. The Programming Key initializes the lock so that the default combination can be changed and manager keys can be added. The Manager Key opens the lock and changes the combination even when codes are forgotten or batteries depleted. One Programming Key and one or more Manager Keys are recommended per facility.
