MIFARE 1k - KABA SAFLOK - pattern between 2 hotel cards

Card 1 - Access for only Sun 3/1/2020.
Card 2 - Access from 3/3/2020 - 3/8/2020.

Question - Is there a way to create a card that will have access with no time limit (infinitely)?
What would be the solution?

Card 1 - Access for only Sun 3/1/2020:

Re: MIFARE 1k - KABA SAFLOK - pattern between 2 hotel cards

look at the password of sector 1 (2a2c13cc242) this is the password of the locks Kaba/Saflok
the information is encrypted, you need a lot of samples to understand where to look for the data you need

Re: MIFARE 1k - KABA SAFLOK - pattern between 2 hotel cards

I've had some progress discussing with a smart friend of mine. There was something interesting we found:

Check out blocks #16 and #17:

For e.g. converting the first 10 digits of block 16 >> A802D0E2, that converts to 03/23/1923 6:32:18 (UTC)

Converting the Hex to timestamps using a converter online shed some light. I'm still trying to figure out the nuances. But this may spark some problem solving skills.

Also, is there a way to make a master key for this scenario?


 
Card 1 - Access only for 3/1/2020

Block 16: a802d0e220d700530000000000000000
Block 17: 00000000000000000000000000000000
Card 2 - Access from 3/3/2020 throught the rest of the week

Block 16: 008c831c89200000a802d25e20d800d2
Block 17: a802d25e20d800d2a802e20720d7008a

Forced to disappoint you ((( locks never use UNIX time. Because time is counting MK41T56/MCP7940

Any leads or hints would be greatly appreciated... Or we can work a deal ($$) for "consulting" work.

Re: MIFARE 1k - KABA SAFLOK - pattern between 2 hotel cards

You did not confirm/refute my guesses about the type of lock )  Kaba/Saflok? On two card dumps - cryptanalysis not possible. You will need a lot of dumps, and a lot of time ...

You also did not indicate the check in time, check out time, and hotel room number

Re: MIFARE 1k - KABA SAFLOK - pattern between 2 hotel cards

The cards are KABA and specifically access the hotel elevator. The goal is to have a "Master" card access that will be able to access the elevators for a desired length of time. Currently they can only produce cards for a certain time for several day.

I discussed with my friend about the out the check in time, check out time and hotel number and he can easily produce those.

We can play with the scenarios.

And have him to produce different variables:

For e.g.

Hotel Number: 123
Check in time: 4/1/2020 3pm
Check out time: 4/3/2020 11am

Here is an interesting pattern for you)
a8+02+d0+e2+20+d7+00=353
a8+02+d2+5e+20+d8+00=2d2
a8+02+e2+07+20+d7+00=28a
