Help! immobilizer issue!

So kinda need ur help all..today my truck would crank but doesn't catch..I notice that my immobilizer light was blinking..anyone here had this issue and how u fixed it?..thank you in advance all!

 

Push-button start, or immobilizer key? Assuming the latter for now.

Hopefully you have a second key, I’d try that first.

 

just one key..I'm trying to figure this out before I go to the dealership for the fix

 

If it uses a key I would for sure try a different one if you can.

 

Only one key isn’t a good thing. Any other transponder keys on the same ring? If so, try removing them.

 

Man this is way more common than I thought. I removed my remote start and started carrying my spare key in the truck.
