I have 2 temp cards for my unit - One that was available for 2 days and 1 that was available for 7 days, both worked on the same door, but stop when the timer runs out. I want to make a card that indefinitely works, so I compared the data and keys on both cards to find the timer. Nothing has a 2 to 7 ratio or 2 minus 7 number, or a date that I can decipher in Hex or Dec.
Anyone have insight on where the timer is? This is for an Assa Abloy Essence lock
Any help would be appreciated.
The different lines are line 0, 7, 24, 25 & 27 (All other lines are the same)
Line 0 UID (1st line is 2 day card)
A0131B8028880400C802002000000023
A025A78CAE880400C804002000000023
Line 7 Key

Line 24 Data

Line 27 Key

My next step is to change this data to the default values to see if the timer goes away, but I’m sure someone here has a better suggestion. Thanks
I know that for my lock at home (also battery powered) I can buy an add on WiFi hub, with which I could add additional locks, and control access to all connected locks; this might be how your ones are “networked”
I’m not saying they are, just a possibility, and to me the more logical way to manage access rather than on the card itself
Yes, that is my system, but I am 99.9% sure they are not networked.
Mgmt needs to come to the unit to program it when the key fob is lost and needs to be changed (I assume the other line item keys that match between cards). Mgmt told us they are not networked as it required extensive infrastructure and cost, the common wifi does not reach to all units to be networked and they are not wired. Thanks for the interest and help.
Ohh.
Thats a good idea. I had to hand back in the 2 day card to get the 7 day one. I will try to keep the 7 day one and get another card (Not 7 days) soon and post the results in a few days. Tks again.
OK well, I made copies of the cards and compared them. It did not find lines 7, 24, 25 & 27, they were all zeros, so they came up identical. The only differences it found were in the UID.
Hmm, Interesting. I discounted that as its part of the cards manufacturers data, but if the lock is using that and its programmable, then that could be it. I will look at other cards I have copied and see what they are, modify it and get back to you. Thank you
