I could suggest "Infinite Noise" [1] keys which are also open hardware.
They use a different design, based on "modular multiplication" which
should be immune to most RF noise, 

The original model is currently sold out[2] but a fork exists[3].

One can also have a look at OneRNG [4][5] which uses a more usual
design but adds a nice EMI shield protection.
