My mum lost one of our remotes for garage door opening so I need to buy a duplicator to clone signal from second remote we still have. BUT, the remote is quite old and works on frequencies 27 MHz (garage 1) and 40 MHz (garage 2) and most of new remote control duplicators work on different frequency e.g. 433 MHz or they are expensive (I wanted to order something from China for 3 bucks). Is there any way that 433 MHz could work with our garages or can you recomend cheap 27 or 40 MHz duplicator?
