Came out of restaurant today , punched the door fob , battery in fob was dead . I could have unlocked with key but next door was Auto Zone , replaced battery , all fine ! My question is if fob battery was 100 % dead would my 2014 Ram 2500 CTD have started , does the fob have to have juice for motor to run ?
Can’t say about your truck, but the keyless entry system on my BMW X5 works with a dead fib battery. Both the door lock and the ignition use near field chips, so if the car senses the key within 5 feet of the door, it will unlock when you touch the handle, and as long as the key is inside the car, the engine will start and run. Of course, the fob buttons require the battery to work.

Are you saying the truck will sense the presence of the fob even if it's battery is dead? Will keyless entry work with a dead fob battery?
I can open my F350 without the key or the fob just push the combo to the pad.
