Most keys are Hitag2 and now have password mode on.

Re: car key eavesdropping

For Hitag2 protocol with password mode, it should be still possible to execute a relay attack (real car key being far away from the vehicle), right?
Real_Key <--LF--> Proxmark_1 <---> Proxmark_2 (Proxy/Simulate Real_Key) <--> Vehicle Immobilizer

Is there any support for this in the current firmware and libs? I couldn't find anything.
Any kind of input would be very appreciated
