E350/450 Keypad (Keyless Access)
After trying the two major keyless lock suppliers for the house door (fit issues with both, for me), I stumbled across something which is a good compromise for me, by happy accident.
I have occasion to use a transit, and realized the door keypad is a stick on item. Ford offers the same thing which does work on many E chassis (and other Ford products).

This is a stick on the door pad, which easily snycs, just as a fob does. For us, I placed it on the pass side, since that is the side we would want to access when camped. It allows us reasonable keyless access, and easy forgot or lost the key access (spare keys are inside).
