Finally decided to go with this one after emailing back and forth with their customer service rep to go over what we wanted out of a lock and how the features of this one could fit our needs. First before jumping into how good the product is, I just want to give a shoutout to James from Colosus who was so attentive to what we wanted and would even ask us follow up questions that made us realize we needed to approach this purchase as more of buying a system and not just a lock. Here is what sold us on this product: 1. The ability to connect all NDL302 locks with key fob/code 2. Open mode which keeps our front door open during business hours for our patients 3. Remote control which allows our receptionist to unlock the door for patients to come to the back right from her seat. 4. Key fobs for our doctors and codes for our other employees 5. The best 1-on-1 customer service reps that attend to you and follow up with you to make sure that everything is running smooth. If you’re looking for a digital lock system for an office, I would highly recommend talking to James from Colosus or just email or call them to see if this lock is right for your needs. I just wish they also had a team that would come install this because that would be the complete package. Review: Not sturdy, screws stripped easily with regular use.

After light use the screws that hold it together at the bottom started to strip and lock became very loose and quit working ### ⭐⭐⭐⭐⭐ Great lock, with the ability to add multiple entry passcodes, I like this lock. *by J***N on July 14, 2023* Great lock, with the ability to add multiple entry codes. I'm very happy with this door handle's sturdy feel and contemporary good looks. It is relatively easy to install, but it is a bit troublesome to drill another hole on the door. Of course, the door lock is installed more firmly. It is easy to set a password to open the door, and it is very convenient to open the door with a IC card and a remote control. Anyway, I like this lock. ## Frequently Bought Together - Electronic Smart Door Lock, Keyless Entry with Keypad, Key Fobs, Remote Control, Keys for Home, Office or Commercial, Silver NDL302 - Colosus NDL302 Keyless Electronic Digital Smart Door Lock Key Fobs (2 Key Fobs) - Colosus Elongated Latch 70mm for Smart Door Lock Keypad/Touchscreen --- ## 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.hr/products/111295179-electronic-smart-door-lock-keyless-entry-with-keypad-key-fobs](https://www.desertcart.hr/products/111295179-electronic-smart-door-lock-keyless-entry-with-keypad-key-fobs) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-14*
