This sounds like an unusual issue and hopefully your dealer service department will be able to make things work correctly.
I have exactly same issue. I leased it yesterday and worked well but today morning key fob doesn't work. Grand Cherokee doesn't recognize key at all. When I open the door using the key manually, theft alarm issues and car doesn't recognize the key even inside. Nothing works.So after picking up my brand new Grand Cherokee L, drove home, parked the jeep, hit the lock button on the keyfob, everything was fine. Go back to the car, keyfob not working, checked other keyfob, also not working. Called dealer had to have them tow the vehicle back to the dealership...... Dealership in diagnostics with Chrysler (Mopar) whomever to figure out what is going on. The Grand Cherokee will not recognize the Keyfob. Apparently something wrong with the antenna or module in the vehicle. After the disconnected checked out some items, they reconnected and the keyfob was working fine. They tested it for a day, all working, kept it overnight..... this morning, same problem. Anyone know a solution to this brand new car nightmare? Bought Saturday, towed Sunday, still not able to drive it. The guy that answered the call for Jeep Wave said he had 4 more calls form owners of brand new Grand Cherokees with the exact same issue that day...... I'm assuming this is all technology software issues, but it could be a bad batch of hardware. Thoughts?
Roadside assist towed my L today morning and spend whole day there. Not yet fixed and just keep sending theft alarms via app and email.I have exactly same issue. I leased it yesterday and worked well but today morning key fob doesn't work. Grand Cherokee doesn't recognize key at all. When I open the door using the key manually, theft alarm issues and car doesn't recognize the key even inside. Nothing works.
At least you got 3 days trial period. I got only 15mins of trial period. I heard it was delivered to the dealer last week(between 2/7~11). I purchased it on 2/12 and died at the same day. S/W update doesn't fix the issue.Our 3 day old L did this same thing today, towed to the local dealer. Any idea the build date on yours that are having this issue? Ours shipped to the dealer from the factory about a week and a half ago. Pretty disappointing to have a completely useless vehicle with this issue. And then watching everyone we talked to look at us like we were idiots, just use the key, and hold the fob here. No, it's D E A D dead.
If the key fob stops working can you still use the Jeep app to unlock the doors and then drive?
My neighbor has a 22 JGC, that's not the L model it's not here so I can't look at it to tell you which one it is but on tuesday of this week he had the same problem. He said that the remote start wouldn't work on his wife's key Fob but on the one he has it did.So after picking up my brand new Grand Cherokee L, drove home, parked the jeep, hit the lock button on the keyfob, everything was fine.

Recent purchase like the rest? Seems like all the dead ones were manufactured and purchased around the same time. Has anyone got there's back yet and working? I'll be shocked if I get mine back this week.Exact same thing just happened to me, and now towing the car to the dealer 🤯 I’ll spare you the detailed of a 6 hours long saga with the roadside assistance company 🤬
