SecuraKey Cards

I have 60 SecuraKey RKCM-02 cards. There's ~50 with one FC, and another ~10 with a different FC. Can take PayPal or LTC. Shipped for free via Priority Mail. Make me an offer. Also willing to donate these if someone can get some research done on them in order to make them fully implemented in Proxmark's firmware.

Re: SecuraKey Cards

Don't I need the cards itself,   just trace dumps from them will do.

How did you go at this? Since you are now selling your cards...

33629 and 33850 are FC 11. 57432 is FC 10. I also have the RCKM cards with FC F3 if posting more traces of those would be helpful.

And I wasn't able to end up getting them cloned unfortunately. Unless someone can now offer a solution.

Re: SecuraKey Cards

when you say FC is 11 and FC is 10, is that what is printed on the card or what is read by the access control system?

Re: SecuraKey Cards

I'm guessing but to me 0xB, 0xA would be FC 11, 10...

Re: SecuraKey Cards

yes but normally the external codes don't match the internal one.  (At least on all previous samples)  plus the external code historically is always hexadecimal.

Re: SecuraKey Cards

yup,  true,  @atyppo has not posted any info on printed details.  That would be nice to have a list of read data,  tracesample file and printed information in a nice clean neat list.   One could wish for less but why?

It is what is read by a Linear AM-DPR card reader (manufacturered by SecuraKey I believe) using Linear AccessBase software. These are embedded tags in a gate opener.

i assume you don't have these physical tags or don't know what was printed on them then?

i'm still not sure how the "Code" or Facility code printed on the card is related to the internal FC (if it is at all).

Re: SecuraKey Cards

Its more a question of running the same commands over each cards,  to gather the needed data and paste in the interesting data parts into a text file and putting the saved datatraces in a folder.   No hi-tech.

lf securakey read
lf read

--replace UID with found fc/csn 
data save  UID.pm3

Here's the traces: https://uploadfiles.io/wzul1 These tags are in Linear's ACT-31D transmitters.

I may be able to get access to another SecuraKey RCKM-02 tag with another facility code on it tomorrow. Also, I have several IDteck (Doorking branded) tags if any info from those would be of use.

Re: SecuraKey Cards

Nice!

The general recommendation is to collect as much data you can.  We never know when it might get in handy when trying to figure things out.

How many more samples would it take to get something implemented where tags can be written bassed on SN/FC?

What I meant by that post is how would I be able to write a given SN? FC isn't really needed as Linear's system doesn't check for FC unless it's been manually turned on.

Here's tag no. 13412 with FC A6.  The FC is read as 006 when using the *82 function on the Doorking 1837 system it is attached to. Also, FC F3 shows up as 053 on this system. Given that current Proxmark firmware shows up with 0x35 as the FC, I believe the FC's digits need to be reversed? May be wrong on that. FC 10/11 still don't make sense. Perhaps I'll also take them to this system if I get a chance.

Re: SecuraKey Cards

To me, it looks like it goes
A-00x
B-01x
C-02x
D-03x
E-04x
F-05x
...and so on with the number at the end of the FC listed by SecuraKey being the x in these numbers. I'll do my best to get what was read as FC 10 and 11 by a Linear reader to the Doorking reader ASAP and see what the output is on that. Is there any way to take, say card no. 42038 and FC 0xB, and copy it onto a T5577 card right now or do further samples need to be posted?
