Our locks have an IP rating of IPX4 and are rated for -4 degrees Fahrenheit (beyond the freezing point) up to 140 degrees Fahrenheit. Our locks are weather resistant but are not weatherproof, and they can be used on exterior doors as long as there is an overhang or awning. We do not recommend using our locks without protection from direct weather such as rain.
If the lock will be under constant direct sunlight and heat, we recommend purchasing our sun visor that adheres to the exterior assembly of the lock to protect the display screen. The sun visors are available for purchase from us directly for $9.90 and come in either Satin Nickel or Matte Black. Please let us know if you would like to purchase a sun visor, and we will email you an invoice for payment.
