getting a second (and third) remote entry solution

[Effduration]

Hey Oldskewel, Is there a convenient way to charge key fobs outside of the car?

I like the idea of used genuine key fobs as extra remotes, but I remember reading that if they are hanging on a key chain they aren't close enough (or are not positioned correctly) to be charged by the induction charging of the ignition.

I have heard that certain phone and toothbrush chargers can charge our fobs, but haven't see a definitive solution.
