I have the same problem. Unenrolling/enrolling the BE469 are the same process: Extend deadbolt => [SCHLAGE] button => 6 digit programming code => 0. Either way, after initially enrolling successfully but not being able to properly see it as locked or unlocked in the Securifi web interface, I removed all sensors from Almond+, reset the BE469, and have since been unable to enroll/unenroll the BE469. Every time I try I get the red "X" instead of the green check.
