Setup, Compatibility & Care
Proper installation begins with accurate measurement. You must measure from the center of the fixing screw hole to both the internal and external edges of the door to get your exact size (e.g., 40/40). To install, remove the existing cylinder by unscrewing the central fixing bolt located on the edge of the door, slide out the old unit, insert the new UAP cylinder, and re-tighten the bolt carefully—avoid over-tightening as it can stress the cam.
For care, avoid using heavy oils or grease inside the keyway, as these can attract dust and dirt, leading to potential jamming. If the lock feels stiff, a dry graphite lubricant is recommended. Keep your Bio Keys clean and dry to maintain the antimicrobial properties.
