A subset of smart locks made by Lockstate have been bricked after an update. The smart lock vendor is part of Airbnb’s Host Assist program, and integrates with the accommodation rental platform so, for instance, hosts can automatically generate and email one-time codes for their guests to use during check-in.

TechCrunch was alerted to the problem by a Lockstate customer, Ruffin Prevost, who forwarded us the email he had received from the company informing him of the “fatal error” following a software update.
