Very poor programming instructions. Provide please more detailed programming. Thanks** A: They can be programed seperatly but you cant have one toggled and one momentarily...dont know why...just cheap rubbish i suppose **Q: What type of plug do I need to connect the unit to the mains in uk?** A: This unit must not be plugged directly into the mains. It works via a power pack which will need to have a D.C. output of suitable voltage (presumably 12 to 24v) There was a suitable power supply within my door closing unit, so I utilised this. Hope this helps. **Q: what is the range of the remotes?** A: In my experience the range is between 3m and 6m varies between fobs. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Exactly what I needed *by K***N on 5 May 2021* A little confusing over the instructions but once sorted works great ### ⭐⭐⭐⭐⭐ Good price *by E***. on 9 September 2024* Easy to fit, good price and good functionality. ### ⭐⭐⭐⭐ Cheap solution for a garage door opener *by N***R on 25 June 2022* When my garage door opener stopped working I installed this. The instructions that came with it are awful, and I had to look online to work out how to program it, but once programmed it has worked faultlessly. The range is acceptable. ## Frequently Bought Together - QIACHIP DC 12V 24V 433mhz Wireless Radio Remote Control Switch RF Relay Receiver Board 2CH 10A with 2 Transmitter Key fobs for Motor, Light, Gate Door, DIY Controller - YANGHX Maglock Magnet Electric Lock Flush Mount Embed Installation for Single Door 280KG (600LB) Holding Force - RoyPow Deep Cycle LiFePO4 Battery Pack 12V 6Ah Lithium Iron Phosphate Battery 3500 Cycles Rechargeable FiOS Drop in Replacement of SLA Battery, for RV/Camper, Kid Scooters, Fish Finder --- ## 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.gr/products/272979144-qiachip-dc-12v-24v-433mhz-wireless-radio-remote-control-switch](https://www.desertcart.gr/products/272979144-qiachip-dc-12v-24v-433mhz-wireless-radio-remote-control-switch) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-19*
