The only struggles installing were due to the age of our home - the bolt is larger than our old locks and requires some additional wood to be chiseled out of the door jamb to allow proper function. Not the locks fault and makes me feel like it is a better quality lock, just wanted to call that out. Integrated seamlessly with the eufy home app. We love being able to unlock the door from the car when we’ll have groceries or something, or when it is raining so you don’t have to stand outside any longer than needed. Also allows remote unlocking - a family member stopped by the house when we were at work and we could simply lock and unlock for them from another city. Comes with physical keys as well so you have a backup. For the door that gets the most use, the batteries last a few months and you have tons of notice when it is time to replace them. Have never had an issue where we were locked out because the battery died, and even if you did you still have the physical keys. You can set up to 8 digits for the code, which I like. The buttons have held up well and the locks still look good a year later after install. Review: Resolves adhd marriage problems - If you are tired of your adhd husband leaving the front door unlocked when he leaves for work before the sun comes up, this will solve all your problems. I no longer wake up angry and ready to start an argument about him inviting robbers in the house while I sleep. I was able to set up auto lock for the hours I know that he would be leaving and arriving home. Features I love are that you can unlock it remotely from anywhere (great for letting house sitters in and out), you can set up codes for all members of the family so you know who unlocked the door and at what time, you can set up notifications for when it was unlocked (perfect for toddlers that want to run for the horizon as soon as you close the bathroom door). The only complaint I have is that the battery life is lacking. In 4 months we have had to change the batteries twice already and this thing takes a lot of batteries! ## Features - Remote Control from Anywhere: With built-in Wi-Fi and no bridge required, you can effortlessly control your smart lock from anywhere using the eufy Security app. Enjoy easy setup, access management, real-time notifications, and event history. - Smart Lock: Easily open your door using a physical key, voice commands with Alexa/Google Assistant or a physical button. eufy smart lock's physical buttons offer enhanced durability and error resistance, providing greater reliability and usability than touchscreens. Auto-lock secures your door if you forget, locking automatically based on your time setting, whether the door is open or closed. - Easy Installation and Excellent Customer Service: Compatible with most standard Deadbolts. The 15-minute DIY installation requires no drilling. eufy is on standby for you 24/7. Enjoy a 18-month protection backed by professional customer service. - Integrated Smart Home: Pair with a eufy doorbell to seamlessly integrate your smart lock into daily routines. Control all your devices for smooth keyless entry via the eufy Security app. - Security and Durability: Our eufy smart lock is powered by 4 AA batteries (not included) and has a battery life of up to 5 months.

The smart lock's wrong-try protection temporarily locks the system after multiple incorrect attempts, deterring unauthorized access and enhancing your home's security. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DJ2BX2JN | | Additional Features | Auto-Lock, Passcode Unlock | | Best Sellers Rank | #6,198 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #38 in Deadbolts | | Brand | eufy Security | | Brand Name | eufy Security | | Color | Black | | Control Method | App | | Customer Reviews | 4.2 out of 5 stars 409 Reviews | | Included Components | Lock | | Item Dimensions | 2.57 x 1.63 x 6.05 inches | | Item dimensions L x W x H | 2.57 x 1.63 x 6.05 inches | | Lock Type | Deadbolt | | Manufacturer | eufy | | Manufacturer Part Number | Anker | | Material | Metal | | Material Type | Metal | | Model Name | T85D0112 | | Model Number | T85D0 | | Number of Items | 1 | | Number of Pieces | 1 | | Special Feature | Auto-Lock , Passcode Unlock | | Style | Traditional | | Style Name | Traditional | | UPC | 194644216382 | | Unit Count | 1 Count | ## Product Details - **Brand:** eufy Security - **Item dimensions L x W x H:** 2.57 x 1.63 x 6.05 inches - **Lock Type:** Deadbolt - **Material:** Metal - **Special Feature:** Auto-Lock, Passcode Unlock ## Images ![eufy Security Smart Lock C30, Keyless Entry Door Lock, Built-in Wi-Fi - Image 1](https://m.media-amazon.com/images/I/518rhM8EFML.jpg) ![eufy Security Smart Lock C30, Keyless Entry Door Lock, Built-in Wi-Fi - Image 2](https://m.media-amazon.com/images/I/61431ETesyL.jpg) ![eufy Security Smart Lock C30, Keyless Entry Door Lock, Built-in Wi-Fi - Image 3](https://m.media-amazon.com/images/I/71qx8gRpyuL.jpg) ![eufy Security Smart Lock C30, Keyless Entry Door Lock, Built-in Wi-Fi - Image 4](https://m.media-amazon.com/images/I/71H8La+vHiL.jpg) ![eufy Security Smart Lock C30, Keyless Entry Door Lock, Built-in Wi-Fi - Image 5](https://m.media-amazon.com/images/I/71l-yz5fm-L.jpg) ## Available Options This product comes in different **Color, Style** options. ## Questions & Answers **Q: How many passcodes can the eufy Smart Lock C30 store?** A: Up to 100 different passcodes. **Q: How long does the battery last from one charge?** A: Roughly 5 months depending on usage (based on unlocking the door 20-30 times per day).

One thing I really appreciate is that it hasn’t dropped the WiFi signal or lost connection since I installed it. It stays reliably connected, which is really important for a smart lock. The app is also very well built and easy to use. Everything is laid out clearly, so it’s simple to manage settings and check access. I like that it works with Alexa too, which makes it convenient to integrate with the rest of my smart home setup. Another feature I really like is being able to add multiple users and customize their access. You can give different people their own codes, which is great for family members or guests, and it’s easy to manage through the app. Installation was pretty straightforward as well. As long as you follow the instructions step by step, it’s not difficult to set up. Overall, it’s a reliable smart lock with good connectivity, a solid app, and useful access controls. ## Frequently Bought Together - eufy Security Smart Lock C30, Keyless Entry Door Lock, Built-in WiFi Deadbolt, Smart Lock for Front Door, No Bridge Required, Easy Installation, App Remote Control, Auto Lock, Traditional, Black - Blink Video Doorbell (newest model), Two-way audio, HD video, motion and chime app alerts and Alexa enabled — wired or wire-free (Black) --- ## 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.de/products/670105083-eufy-security-smart-lock-c30-keyless-entry-door-lock-built](https://www.desertcart.de/products/670105083-eufy-security-smart-lock-c30-keyless-entry-door-lock-built) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-08-09*
