BitLocker Recovery Key Asking on Boot Windows 11 Fix [2026]

Quick Answer: BitLocker asks for recovery key on every boot because it detected hardware changes or BIOS updates. Suspend BitLocker, restart, then resume to re-seal the TPM.

Symptoms

BitLocker recovery key screen on every startup
Key saved to Microsoft account works to boot
Started after BIOS update or hardware change

Root Cause

TPM sees changed boot configuration (BIOS update, new drive, RAM change) as potential attack.

Method 3: Check TPM Status
