# Cloning cards/fobs with a Proxmark3
|
|
|
|
## Cloning a Paxton fob
|
|
|
|
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, emulating an EM4100 chip:
|
|
|
|
```
|
|
lf em 410x clone --id <your hex 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.

## Cloning MiFare cards
|
|
|
|
See [Cloning a Mifare Classic 1K](https://www.gavinjl.me/proxmark-3-cloning-a-mifare-classic-1k/).

## Card cloner password
|
|
|
|
I have an AliExpress cloner which clones LF cards. Unfortunately, whenever it clones a card, it sets the password bit on it. This makes the card not respond to writes/wipes without the password (it just keeps having the same data, no matter what you write).
|
|
|
|
To remove it with the Proxmark3, run:
|
|
|
|
```
|
|
lf t55 wipe -p 51243648
|
|
```
|
|
|
|
|
|
## Cloning T5577 cards
|
|
|
|
Read the card with:
|
|
|
|
```
|
|
lf em 410x reader
|
|
```
|
|
|
|
Write with:
|
|
|
|
```
|
|
lf EM 410x clone --id <the ID from before>
|
|
```
