I leaned this because my girlfriend has the spare FOB and keeps it in her purse and then will leave the purse in the truck when we're out and about without telling me until the truck screams at me when I try to lock it from the door. [emoji23]Hmm [emoji848] I have no key. Keyless entry and push button start in my 2016 TRD OR and it will not let me lock my truck if my FOBS are inside unless I push lock on a FOB. So I can only lock a fob inside of I use a FOB to do it. The truck will literally scream at me if I try and use the door to lock it with a fob inside.
