How do I install the Schlage BE489WB deadbolt on my door?

First, remove your existing deadbolt including the bolt and strike plate if necessary. Adjust the bolt length so the slot is centered in the hole with "TOP" facing up. Install the strike plate into the door frame, then route the cable through the door below the bolt, aligning the tailpiece with the slot. Finally, secure the backplate with screws, ensuring the outside touchscreen is straight before fully tightening. (Page 1 — Setup Instructions)
