[QUOTE="OptimusPrime, post: 1538059, member: 35063"] It can happen. Thought I was broke down. Was told to pull the keys out of the box and it fired right up. That being said, knowing how an ignition system works I don't get why it would need more power for keyless than keys. You click your fob, it sends a signal to the truck that it is safe to arm the switch, and in theory, the switch works the same as turning the key. It completes the circuit for the starter and current is sent to it. And the weird thing is the receiver that gets its signal from the fob still functions with a low battery. It will arm the switch. Green light flashing and all. It just wont crank. Only thing I can think of is some odd failsafe built into the system so it doesn't function with a low voltage battery. Something along the lines that it would be better for the truck not to start with a gimped battery to only have it fail later on down the road? I really can't figure why they behave this way.
