My NExT implant dont work with RFiD as usual

As @APartOfMe suggested, and when you are trying to read your implant, your NExT should be perpendicular with the antenna, like this


Anywhen on the Antenna ring should be fine, you ar just trying to get that Right angle :triangular_ruler:

You may need to press firmly.

Also, is the HF side still working?

What about hf side (NFC) it still working as expected with my and others phone, but not readed by pm3.

Thanks for reply, when I have some results I contact you

Check this video at the 1 minute mark;

It talks about the high frequency antenna and how to read implanted chips with it.

Hi All!
I finally found my chip, it was VERY HARD.

Any idea guys?

If you’re able to read your implant with the pm3, then all that’s left is to clone the card. What type of chip does your RFID card have? Put it on the pm3 and run lf search if you’re not sure.

Ok, I will do it tomorrow.
The point is that the problems started spontaneously. I always opened the door with an implant, but once the lock just stopped responding to it. checked on other locks of the same type, does not work.

sort of… i’m guessing he’s not attempted to do much with his NExT at this point and so it should be in EM mode by default… yet he’s getting a detection of TI with bad checksum… this screams coupling problem to me.

  1. is your next fairly close to the skin? can you see it and / or easily feel it when you poke around with your finger?

  2. have you tried using the lf tune command to figure out exactly the best spot?

  1. are you possibly shorting out your LF pins when using?
  1. Yes, my NeXT very close to the skin, I see it when I clench my fist.
  2. No, but I try and give a results.
  3. Maybe, but I not surе. I will try to reproduce

That was my first thought as well, but since he said that he had his card copied on there already, I assumed that was probably it. An lf search on the key card would still be very helpful :wink:

When I do hf tune I see this ↓

When I do hw tune I see this ↓

So the point of lf tune is to show the voltage levels over time through constant sampling, and you watch those levels as you present a tag… you should see them dip down as the tag begins to couple with the LF antenna. At some point there will be a maximum drop… and this indicates the best position and orientation you have presented the chip to the antenna at (so far)… look for the maximum voltage drop and once you find that position with your chip, try to run commands with your chip held in exactly that position.

The output you get from lf tune looks like I would expect from lf help. I suspect some sort of hidden character in that tune, but if that is all you get then double check your Proxmark3 setup… Possibly even wipe and reinstall.

I quickly looked over this post to get the facts and see what has already been established.

From my understanding your keycard is an EM410 with the ID 001A338701
I am guessing that the T5577 data you got was from the NExT? If so, that is good and to be expected.

From the output you gave of lf tune Ive got a feeling you are running an older version of the client.
Could you share the output of the command hw version please?

The tricky part, from my understanding, is trying to get placement on the proxmark LF antenna so that it couples well and issuing the command on the client to read said implant.
You can issue multiple proxmark commands in the one line to be executed sequentially by using a semicolon between each command. For example, if you wanted to run 3 low frequency searches back to back you can issue lf search; lf search; lf search on one line and press enter.

Once you have been able to get used to positioning your hand and the proxmark so that it couples well, you can move on to writing new data to it. The good news is that copying an EM410 card to a T5577 is fairly straightforward. But I would like to know the output of the version command above plus the assurance that you are getting better reads before suggesting a write.

Looks like you have the RDV4 client installed but you are using an Easy thus there is a mismatch and you will have more of a headache if not corrected.

How have you installed the client? For example, precompiled or proxspace or MacOS Brew or Linux compiled

With that answer, we can move forward and correct this mismatch before trying anything else.

I`m installed all soft from these manual Getting started with the proxmark3 easy

If that is the guide you followed then I would like to ensure you followed Makefile.platform as it does not appear these settings have been applied
