I needed a new remote control door unit for my garage door and naively went to the garage door specialist for a new one. It cost me $130. I thought this was way over the top. It's just a small plastic device with a dip switch, push button, circuit board and battery, made in China for well under $10 I bet.
I looked up TradeMe when I got home. No one selling them there. I looked up eBay.com.au. Plenty being sold there for a range of prices, all of them substantially less than what I paid. I even found a retailer in the U.S. with a big range for sale, the vast majority of them at less than $20 US.
So I now feel as though I have been ripped off big time. The only thing I need to know before I purchase is what frequency the remote control operates at. And of course there is nothing on the old remote or the door door opener itself to tell me this, strange I thought. But even so I could have purchased both the two of the main options (315 MHz and 390 MHz) and thrown one away and I would still have been better off financially.
Does anyone know of a better way to find out what frequency the remote works at?
