Thinking about a 18 exployer, xlt, pust button start, is there a way to start the car if the push button start stops working? Tks

May be similar to an Ignition Switch Failure. Repairing is the solution. Bypassing and overriding is possible. Do they have a high failure rate. Google your vehicle and Push button start failure, see if you get a lot of results? If not too pricey, carry a spare?

What good is a spare If the push button don't work

Its under warranty, get the dealer to mess with it, it's a 2018, its not even a year old yet.

What good is a Spare? Usually New Spare Push Button Switch should work. Please don't carry a Broken Spare Switch. Do you feel that Switch is the Next/First thing to fail. They Must have a high Failure Rate if it has you worried, There are hundreds of different things on a car that can fail, to prevent the car from starting/Running.
