I've got a card that I'm having trouble cloning. It looks to me to be an HID H10301 format card, but when I clone it to a t5577 card it doesn't open the door. Both my proxmark3 easy and my white chinese hand held cloner think they have cloned it. I suspect that there is something that should be obvious that I've missed and would appreciate a shove in the right direction.

Architecture Identifier: AT91SAM7Sxx Series
Nonvolatile Program Memory Type: Embedded Flash MemoryI verified that the card was only 125KHz with the "hw tune" command, and only saw a voltage drop on 125KHz when the original card was placed on either the lf or hf antenna.
I did an "lf read" and a "data save" command on both the original and the clone cards. The .pm3 files are:

clone: https://drive.google.com/open?id=107xkwlBWUmJJqp_TrNJx40lIPDXnM9dX
"lf search u" on the original card gives:
proxmark3> lf search u
NOTE: some demods output possible binary
if it finds something that looks like a tag
False Positives ARE possible

Try lf t55xx ... commandsThe number printed on the original card matches the Card Number (06671).
So that is what I know about the cards. Can someone please give me a point in the right direction on what to look for next?

An interesting note. The clone card will open the parking garage and the perimeter security doors, but not the room door.
I tore apart the door handle and found the problem with my cards...
These darn door readers are Magstripe only! So the parking garage and security perimeter are HID 10301 and the doors are Magstripe only. No wonder they were giving me fits.
They have non standard format code on track 3 only. I was able to do a raw copy and have functioning spare keys. I've ordered some t5577 cards with hi-co stripes so I don't have to have two cards for her door.
Sorry for bringing you guys down this rabbit hole!
