Bstsilver Fingerprint Refrigerator Lock 20Users for Adults & Teens – No Drill Adhesive, Adjustable Pet Door Latch w/Emergency USB Key, Childproof RV Smart Biometric for Fridge Cabinet Drawer Window

About this item

• No keys or codes – your finger is all you need. Stores up to 20 fingerprints. Includes USB backup key & emergency code (set by you). The adjustable steel chain lets you control exactly how wide the door opens – from a crack for fresh air to a gap for passing packages. Use it as a cat door latch or sliding window lock for more versatility. Two ways to install: strong adhesive for no‑drill, damage‑free mounting (leaves no residue – ideal for kitchen & laundry room); or screws for a permanent hold
• Check your size first – measure before you install. Gap between mounting surfaces must be under 6.89 inches; flat mounting area needs at least 1.54” x 3” for the lock body & base. Clean surface; press firmly for 30 seconds; then wait 48-72 hours for adhesive to fully bond. During curing, keep the area dry. Fully charge before install using any 5V adapter or power bank (not included). Tech support included. Ideal for apartments, dorms, rentals, Airbnb hosts & offices – perfect for no-drill spaces
• Detachable fingerprint reader – charge anywhere, add fingerprints remotely. The fingerprint module easily detaches, so you can take it to a friend or relative to program their fingerprint without bringing the whole lock. Perfect for co‑parenting, pet sitters, or grandparents who visit occasionally. Works on French door fridge, trash can & wardrobe. Makes charging simple – just detach and plug into any USB‑C port. To remove: warm with hairdryer, slide floss behind, then rub residue with alcohol
• Works as a cat door latch AND a sliding window lock – two essential functions in one. Set the chain to a narrow opening so your cat can enter/exit freely while keeping large dogs out of the litter box or food station. Or use it as a sliding window lock to customize ventilation – let fresh air in, but keep toddlers and pets safely inside. Perfect for multi‑pet households, busy parents, property managers, RV parks, and hotels who need flexible access control without permanent modifications
• Built to last – strong adhesive & long battery life. Quality ABS, smooth edges, durable steel chain. Strong acrylic adhesive bonds to wood, glass, metal & PVC. Instant response – fast, not hypersensitive (hyper‑speed drains battery). The balance gives instant access + months of use: up to 10 months (5 unlocks/day). Low battery flashes red. Like any biometric lock, it works best with clean, dry fingers – scan at multiple angles when adding. Ideal for fridges, cabinets, drawers, garages & pantries
