Can a landlord change a keyed entry knob in a shared bedroom without notice?

18. Although the tenants had moved some belongings and slept elsewhere for 1 night, I find the roommate agreement was still in effect when the landlord changed the keyed entry knob without notice. I also find unrestricted access to the bedroom and shared spaces was a fundamental term of the roommate agreement, as it is in any such agreement: see, e.g., Buckley v. Madson, 2019 BCCRT 151. By changing the lock without notice and with no intention to provide the tenants with a key, the landlord intentionally breached that fundamental term. I find this amounted to a repudiation of the contract, meaning the landlord showed that she no longer intended to be bound by the contract. I acknowledge that the applicants had largely moved out, but I find they were still entitled to unrestricted access until either the tenancy ended, they did something to justify revoking access, or they confirmed that their move out was complete and they no longer required access. None of those things happened.
