Easy to use. *by M***T on April 6, 2022* Impressive. I live in an HOA neighborhood where everything (parks, dog parks, bathrooms, pools, hot tubs, etc.) require an HOA-issued key fob. My wife has one and I have one. I oftentimes go out for walks with and without the dog and find myself in need I always go for walks in my neighborhood and am constantly leaving my key fob at home with my keys. I’m not sure if the HOA will sell me an extra one or not, but I thought it would be nice to be able to do it myself. I reached out to Tiny Labs customer service to see if my key fob was supported. I immediately got a response advising the make and model had been tested with a 90% success rate. I then decided to buy the Keysy RFID duplicator to see if I could clone it. It worked flawlessly as advertised. I then purchased the Keysy Rewritable RFID Key Fobs and was able to clone it and have the spare key with me on a separate key ring so it was always with me. Out of curiosity, I also cloned a “ProxCard II” card key used to get into my work building. I then purchased some Keysy Rewritable RFID keycards and cloned the card to the Keysy rewritable card and that, too, worked flawlessly. I interacted with Peter from the Tiny Labs Support Team and always found him above-and-beyond helpful and always available to quickly answer questions. ### ⭐⭐⭐⭐⭐ Dependsble *by D***Y on October 15, 2024* Very useful ### ⭐⭐⭐⭐⭐ great *by D***E on July 24, 2023* Ordered a set from the original factory from keysey. I got the reader and a few keys. The reader and keys worked very good. Do not get the cheap 20 pack of blank keys because it will not copy them. I ordered extra keys from keysey. I could clone keys in 2 minutes. very good product and I'm in the process of getting more blanks to sell.. --- ## 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.dk/products/74830334-keysy-rewritable-rfid-key-fobs](https://www.desertcart.dk/products/74830334-keysy-rewritable-rfid-key-fobs) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-05-18*
