Ideal for any residential project, the Yale YRD216 offers a smooth design and easy DIY installation with just a screwdriver. A rubberized gasket protects the lock and door from weather while the tamper resistant battery cover protects against break-in attempts. An automatic 30-second relock of the deadbolt ensures a secure lock every time even if you forget to do it yourself. With the ability to store up to 250 unique codes through Z-Wave, you can ensure specific lock access to a large amount of visitors. Backlit push buttons allow for low light access and a privacy button prevents any access at all. Available in three finishes to suit a number of applications.
