Jumped out of my truck today at the store, went to lock it and wouldn't do anything. Go back to truck try to lock it nothing then try to start it and says key not present, but could now lock unlock doors with fob. Auto start worked but again no key present so no driving. Ended up having to put key in cup holder hole to get the truck to start and drive. Then it is constantly reminding a key not present and that memory recall is not allowed while driving even though I didn't press the button. Changed the battery in fob and problem doesn't go away.

Anyone else have this issue? 2018 Lariat 3.5ECO

 

Do you have the 2nd spare fob thats supplied with all new vehicles?
If so, is the problem still there with the other fob?

 

Yes. Please read my thread on 2017 Limited key quandary.
