Hi all, not sure if this is in the correct section. I opened up my key fob to replace the battery (2017 Prius 2) and I noticed the actual electrical components is like 1/3 the fob size. I don't use the panic function and I can live without the locking buttons because I have the door handle button. So what I'm thinking, is there a way to shorten the motherboard, remove the buttons and keep the key fob on me ? It should only be the size of 2-3 quarters stacked when done. I'd then keep this inside my wallet, so I'd never carry a key on me(house is wireless) Is this a valid idea?
