It turned out to work great!
I didn't connect the module's pins to my keys as planned, but gave them their own GPIOs. I can use a remote with up to 16 keys and read the binary code of each key from the GPIO.
I used 5V to supply the module (because the range is better), so I had to use levelshifters (digital transistors) to the RasPi's GPIOs. It turned out that the range is more than enough for an 11m boat, so next time I will use 3,3V supply and skip the levelshifters.
