Experiences with BitLocker Lockouts: How Common Are They?

From my work at a repair shop, I’ve seen how stressful these situations can be. There was a case where a customer couldn't access their data for months because of a lock due to BitLocker. They didn't even know what it meant when their SSD was locked. Thankfully, it wasn't permanent, but it caused a serious hassle.

I think most lockouts happen due to misconfigured policies or users not backing up their recovery keys. BitLocker lockouts can feel like a modern version of losing a password to encrypted data. It's particularly common with small to medium businesses that enable it without fully understanding the implications.

I've had a couple of near-misses in a pool of 3000 devices, mostly after BIOS updates. If you're in a domain, it's crucial to have Active Directory save those recovery keys. While BitLocker does fail occasionally, I've always been able to recover data since we ensure backups are in place and recovery keys are saved properly.

In my experience managing about 1000 endpoints, I've never lost data to BitLocker lockouts. We use Mobile Device Management tools to ensure recovery keys are saved correctly during setup, which prevents lockout situations. If the configuration is right, it won’t encrypt if it can't save the key, but occasionally, users might delete the object that holds the key anyway.

In my experience, lockouts happen now and then, but it’s usually just a matter of rebooting and finding the recovery key. I've only seen significant data loss once in five years across around 2500 endpoints, and it was due to a series of unprofessional actions from a tech assistant trying to resolve a remote employee's issue.
