Lariat in route - Smaller key fob ideas

My goal is to implement the key fob into my small wallet…

I have done this with a Subaru key in the past - this time I am hoping to 3d print a credit card style Key (not sure how yet)

The new truck has the key code outside - I hate keys

I will keep a key in a RFID bag hidden in the car if needed for valet etc-

Phone app to unlock just in case-

So- any aftermarket key fobs I can either order that Already does this?

Or which Amazon fob can I pair to the truck and dismantle it down to the battery and rfid only

Thanks
