Hello, Keys for the 9105 unit are designed to work on current and existing applications. No need to "rekey" as they are designed to work with all 9105s. Regards STI

        No, this product is designed to protect thermostats and energy sensors, not outlets. It's a tamper-proof cover that helps prevent unauthorized access and adjustments.

        This is highly unusual to hear. The polycarbonate housing is extremely robust and built for years of use. They don't "shatter" unless specifically abused outside of normal use. We apologize for the unfortunate experience.

        The lock serves the purpose of keeping the thermostat from being changed by dementia patient. However it is extremely difficult to lock & unlock. The position of the lock makes it difficult to see how it should have key turned. It is also unsightly.
