Hi all,

Trying to fix an electric entry gate and I have arrived to the conclusion that the remote receiver is fried, door electrics and motor are ok.

This is the receiver, although I'm in Greece this combo is probably US-made, ca around 80s-90s. Brand is Multi-Code. Found new receiver on amazon, thats not my problem. Also found a connection diagram, this unit is probably 24V...

New unit

My issue is that these are easily hackable and would like a more secure receiver/remote. Need at least 3 remotes, whats out there? Mosh shops here still sell stationary and rolling code receivers, are rolling code secure (and can you have multiple remotes)?

Many thanks!

PS: One of many hacking videos on these systems, tests all 4096 code combinations in 10 seconds.

Look at liftmaster 850lm radio receiver. I don’t think easily hackable and it has relay outputs so should be compatible with just about any opener.

Thanks for the fast replies! It looks like I need the Liftmaster or something similar with Security 2.0...
