It’s a very cheap material and hollow. I just replaced with the solid one and works just perfect and better👍👍Just a heads up to the manufacturer and owner of this company.Thanks,Hugo ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Simple quality *by J***A on Reviewed in the United States on April 16, 2024* Wish I had found this lock before buying 5 other types of keyless door locks I have. This one is the best. Great price, easy install and really nice quality. Complete install and programming was 5-10 minutes. I’m very happy with this lock and would highly recommend it. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Easy installation except configuration of passcode *by D***L on Reviewed in the United States on February 1, 2024* Works fine, needed assistance configuring passcode. Need easier steps for passcode set up. --- ## 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.in/products/119479354-signstek-keyless-entry-digital-smartcode-door-lock-for-front-door](https://www.desertcart.in/products/119479354-signstek-keyless-entry-digital-smartcode-door-lock-for-front-door) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-04*
