I replaced a Digicode 5200A keypad with this on my Patriot Gate. My Patriot does not have a US Automatic receiver (433mHz), as is customary in Patriots, which is incompatible with this particular keypad. Mine has a Digicode receiver. This keypad works great! It's of much better quality than the Digicode keypads, which are $68 and absolute junk. I've had 5 of those, and only 1 has ever worked for more than 2 or 3 months. That one has worked 7 years perfectly, but I'd never buy another one after finding this Dolphin keypad. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great product *by J***N on Reviewed in the United States on August 2, 2020* Perfect for my old garage door. Just change the dip switches and worksed perfectly. Very easy to read and understand instructions. Make sure you double check your garage door frequency before purchasing. This is a dual frequency and works for both 300 and 310. Just need to change the jumper. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Read *by D***A on Reviewed in the United States on June 6, 2019* Didn't work for my customers multicode 300hz receiver..you know the one that everyone has...it's grey etc. I've installed gates and intercom systems for about 4 years now...so I think I'm pretty inclined to figure this out had it been compatible. Seller refunded full payment but I had to pay shipping for nothing. Not a big deal but I ended up paying to waste my time. I had to PAY to waste my time. That's all that ticked me off. Oh and I looked like an idiot in front of my customer.... who was anxious to get it done asap so the servicemen can come and go at his business...3 stars because good conceptand because I don't want to be a douche. But it you read up to this point, then I'll be honest-I really give it a 2. Needs to figure out and supply a complete compatibility chart and/or better instructions --- ## 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.pt/products/47370774-dolphin-keypad-300-310-universal-for-multicode-linear-and-stanley](https://www.desertcart.pt/products/47370774-dolphin-keypad-300-310-universal-for-multicode-linear-and-stanley) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
