Problems finding keys

[peterfroehlich]

I have trouble finding the keys for a hotel mfc1k card.

I used the Detect Reader method with little success so I tried the log method:

Side note, I tried multiple times, block 3 only every reported one line.

Converted the output to mfkey32 cmds:

Am I doing something wrong?

[ICURSEDANGEL]

hey have you found a solution to that?

[equipter]

loop timing issue with your reader. try doing it the way that doesn't use detect reader.

[nexus-chebykin]

I have the same issue of not being able to recover keys from logs. Could you please elaborate on what could I do to avoid timing issue? I have a flipper, but I do not see a way to communicate with reader other than using "Detect reader"
Edit: I tried the method using logs, but with no success. And turns out i get a lot of Warnings like:
15:15:38.317 525143610 [W][MfClassic] Incorrect nr + ar
And also a couple of
15:15:38.044 525143343 [D][MfClassic] Error in tx rx. Tx :32 bits, Rx: 64 bits
Is it how it is supposed to be?

loop timing issue with your reader. try doing it the way that doesn't use detect reader.

think my reader hates that

[rhysperry111]

Any update on this? My landlord installed a key access system and I'd like to be able to ditch my card and just use the flipper. Using the detect reader method and cracking the keys with my phone only yields 8/32 keys being found and 2/16 sectores being decrypted (which is not enough for the access system to work)
