Hello

Hello all,

I'm a new owner of an Elechouse Proxmark3 Easy.

I'm trying to read the transponder chips in the keys for my 2005 Subaru, in an effort to reverse engineer the immobilizer system.

I know that these are 4D62 "80-bit" chips, which operate at 134kHZ.

As far as I know these are *not* HiTag chips, and I've been unable to read them using the Proxmark LF HiTag commands.

I did "snoop" a successful read of a key by the actual engine computer, but can't seem to successfully demodulate it into anything useful, so I'm looking for tips on how best to snoop and interpret unknown 134kHZ signals.

Happy to provide the trace(s) I've got as well.

Thanks in advance for the support! The Proxmark3 is a super powerful tool that I'm stoked to have discovered!
