[solved] GProx 2 Cloning

ericlam2728 · 2015-09-26 04:25:25

Hello,

I'm eric and I have fallen in love with this RFID Community.

I recently got my proxmark3 in the mail and have been dying to use it. I've read as much as I can and i'm completely stuck now.

I have a Gprox2 fob and i'm trying to clone it to a tx5577 card so i can tape it to the back of my phone and enter my apartment.

I've looked everywhere and can't figure it out. can anyone help me?

So from what i gather, use the data demod command to get the hex code...? from the gprox card. Then seperate it and use the tx5577 write function to write it to the four blocks on the card?

sounds like a plan to me.

so after running that command I got

G-Prox-II Found: FmtLen 26, FC 10, Card 45952
Raw: fb9436194e511670392e5394

How do i split this into the blocks? i read the threads and I thought you just break that into four parts but that doesnt seem to work. Thank you again for helping out

if you read the threads I linked to, the last one tells you what to do
In short you need a config block and then you split your raw bytes into three blocks.

[b0] config
[b1] fb 94 36 19 
[b2] 4e 51 16 70
[b3] 39 2e 53 94

If you know what modulation and submodulation the tag you want to clone to t55x7, then its a question of looking on the datasheet.. There is an excel sheet which helps out on the courtisy of @asper

infos:
looks like we dealing with
ASk
ASK biphase
3 data blocks
RF/32, RF/50 or RF/64

Is this the Chubb Key some talking about?

Hi , what commands you run to get this raw block?

Thanks for your help
