Requirements

• Proxmark3 with Iceman firmware
• Generic MIFARE Classic 1K cards
• Original Lockly card (for key recovery)

Setup

1. Recover your Lockly card's Sector 0 Key A:

   pm3 -c "hf mf autopwn"

2. Update LOCKLY_KEY_A in the script with your recovered key

3. Configure the pm3 client path in the script if needed

# Batch processing
./lockly_card_writer.sh 10

After programming, enroll cards through the Lockly Home app.

Notes

• The included key (FB5F52DEB87A) may not match your lock
• Script skips cards with non-default Sector 0 keys (prevents overwriting originals)
• For personal use only
