Work every time. Can stop it mid open if you need to reverse. Easily programmed. Seemingly good build quality. Review: You gotta have a cute little fob for this wonderful gate opener! - I’ve already written lengthy, pithy reviews for the TOPENS products associated with my opener! They’re all wonderfully made and working! I’m super happy with my gate opener and my builder has one as well. Okay, the fobs. I love them. They open and close the gate from my house, which is super convenient when friends/family and others come over and I forgot to open the gate. Now, mind you, I have the super daddy opener app which is amazing, and even though we’re out in the country, we have Starlink and finally have great internet service, but you never know, and when that app doesn’t work (and I have other remotes for gadgets, and sometimes they don’t work until you do a rain dance and throw your phone on the ground). Now so far so good, but when we were installing the gate, we had forgotten to set up the app, and ain’t to good at that, so for a few days, all we had were these cute little fobs, and they worked like little champs. And so we have a back up, which is more than I can say for my front door. ## Features - Easy to Program - All the TOPENS swing and sliding gate openers can be operated by the M12 remote. Fast pairing makes it simple to add the remote to your gate opener system using the programming button on the control board. The M12 remote will operate the third-party gate opener whose control board accepts “Normally Open Dry Contact” signal for push button, and connects with our ERM12 receiver (sold separately). The ERM12 can be powered by 9-24VDC from the control board or external power source. - Safe to Use - TOPENS M12 remote control transmitter is a 4-button wireless controller and works with all the TOPENS gate openers. Simply press the button to enjoy instant access to your property. The advanced TOPENS security code technology keeps the gate opener system safe. Small & easy to take wherever you are. The remote transmitter is well built with a durable metal frame for long-lasting performance. - Clever Design - M12 gate remote provides excellent operation range of 65 feet. One TOPENS gate opener can pair Max. 8 M12 remote controls on its own, and up to 250 with the ERM12 External Receiver (sold separately). Every time you press the remote control will make the gate operate between open-stop-close-stop-open. For slide gate opener, button B is designed to activate the midway mode. The 2 x 3V lithium button cell CR2025 batteries (incl.) last up to 1 year at 5-10 activations per day. - Flexible Operation Mode - If there is no signal interruption, one M12 remote can operate countless gate openers simultaneously within the control range. Additionally, one M12 is allowed to control multiple gate operators separately: (1) four swing gate openers (2) one sliding gate motor and two swing gate openers (3) one sliding gate motor, and two more sliding gate motors by adding two ERM12 to each control board respectively, and program button C/D for regular operation without midway mode. - Customer Service and Technical Support - All the TOPENS products come with a 12-month war-ranty against defects, a 30-day exchange & return and excellent tech support.

Easy to program, they have worked flawlessly for the past 5 years, just now needing a new battery install. Highly recommended. --- ## 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.kr/products/55046535-m12-remote-control-4-button-transmitter-for-automatic-swing-sliding](https://www.desertcart.kr/products/55046535-m12-remote-control-4-button-transmitter-for-automatic-swing-sliding) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-04-26*
