How to start truck with dead battery in keyfob

I do a lot of stuff in the back country, sometimes I leave my truck at a trailhead for an extended period of time.

What are my options for a hide a key or a way to start the truck if the fob battery is dead?

Maybe take preemptive measures to insure you donít have a dead battery in said key fob?

Push button start?

I know it is in the owner's manual, there is a way to do it.

Neither type of fob needs a battery in it to start the truck. If itís a push button start, push the start button with the corner of the fob that the panic button is closest to. If itís a regular ignition fob, just start the truck as normal.

I have not verified if it works with the HD trucks but the LD trucks you can pull out a relay and use a jumper wire to start it.

Can't tell if you are serious or just playing here.

He is LITERALLY doing what you are saying to do. By researching what options are available to start the truck if the key fob batt dies. His question is preemptive to a situation where the key FOB fails.

You can't predict battery failure. Mine was working fine, then one day I could not start the truck. I had to use the FOB to press the start button. (Admittedly, I noticed the range was getting worse over a few weeks)

But if you are serious about preemptive maintenance on the key FOB, what is your solution?
Store an extra CR2032?
Replace the batt yearly?
hide an extra key fob somewhere?
