# Cloning a Paxton fob with a Proxmark3 Basically, follow this guide: https://badcfe.org/how-to-paxton-with-proxmark/ I managed to read my fob with: ``` lf hitag read --ht2 -k BDF5E846 ``` If you're getting "Password failed!" or nothing back, move the fob around the 125KHz antenna (the top one), it should eventually work. Afterwards, [convert the fob pages to an EM4100 ID](https://static.badcfe.org/paxton-covert), and flash the ID to a T5577 emulator chip: ``` lf em 410x clone --id ``` Read it back to make sure: ``` lf em 410x reader ``` You should be done, but I haven't tested it as I don't have a Paxton reader handy. ## Related reading * [Iceman's Proxmark3 firmware (use this one)](https://github.com/RfidResearchGroup/proxmark3) * [How to copy Paxton fobs using an RFIDler](https://gist.github.com/natmchugh/18e82761dbce52fa284c87c190dc926f#getting-hold-of-hitag2-tags) * [ How to copy, read and write Paxton fobs and cards with a Proxmark ](https://badcfe.org/how-to-paxton-with-proxmark/) * * *
