MK179: 2 doors/1 key

same tag for 2 MK179 (following)
Hi
you think “it is possible to learn the same tag to 2 units”
:?: but is it only on “low security mode” or it is possible with high security 64 bit code
:!: how to get the same code for my 2 units without it being possible for any user of a MK179
thanks
