At least it did with mine. They are pretty reliable. **Q: Is it water resistant?** A: Yes, but not fully waterproof, you'd better install it indoor. **Q: how do you lock it?** A: When powered on, due to electromagnetic force, the lock tongue pops out and locks. When the door release switch is pressed, the access control circuit will be temporarily powered off. At this time, due to the disappearance of the electromagnetic force, the lock tongue is retracted and the lock is unlocked. **Q: Could two sets of these be installed at the top and bottom of door for extra security?** A: Yes, you can install two sets together for extra security. We generally only install one set one the top of the door, but if your door has enough gap at the bottom for another one's installation, you can try it. ## Frequently Bought Together - LEXI Upgraded DC12V Electric Drop Bolt Lock, Fail Safe Mode with Adjustment Time Delay, Electric Mortise Lock for Door Access Control Silver - AMOCAM K80 Power Supply Control, AC 110-240V to DC 12V Power Supply for Door Access Control System, Video Doorbell, Electric Strike Lock, Bolt Lock, Magnetic Lock, Power Supply Controller - UHPPOTE Momentary Push to Exit Button Switch NO/COM Output Stainless Steel Panel for Access Control Hollow Door --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/403056665-lexi-upgraded-dc12v-electric-drop-bolt-lock-fail-safe-mode](https://www.desertcart.co.uk/products/403056665-lexi-upgraded-dc12v-electric-drop-bolt-lock-fail-safe-mode) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-21*
