[Old Alaska] had a problem. He needed a second remote for his apartment garage door, but was quoted a fee in the hundreds of dollars for the trouble of sourcing and programming another unit. Realizing this was a rip-off given the cheap hardware involved, he decided to whip up his own sneaky solution instead.

It’s a simple hack, cheap and functional. An RF-activated relay with two remotes was sourced online for the princely sum of $8.
