How can I switch my LEHMANN Captura 100 MIFARE lock to shared use mode?

[VanCaleb]

To transition your LEHMANN Captura 100 MIFARE lock from assigned to shared use, you'll need the master card and the "P1: Mode" programming card. Here's how to do it:

1. Ensure the lock is unlocked, and you have both the master card and the "P1: Mode" programming card readily available.
2. Present the master card to the lock's RFID antenna to enter programming mode.
3. Remove the master card and immediately present the "P1: Mode" programming card to the RFID antenna.
4. The lock will emit a brief sound and the LED will flash green, signaling readiness for mode modification.
5. Hold the "P1: Mode" programming card near the antenna until the lock emits a longer sound and the LED remains steadily green.
6. Your LEHMANN Captura 100 MIFARE lock is now in shared use mode. You can test this by using a user card to open and close the lock without needing to reprogram it.

Remember, the programming card set, including the crucial "P1: Mode" card, is a separate purchase from LEHMANN Vertriebsgesellschaft mbH & Co. KG.
