I get these "gremlins" also seems worse when its real cold
I drove with "key not detected" for about 20 minutes last week

My 2014 also sometimes thinks the FOB is in the vehicle even after I've walked away - at least it lets me know with those annoying horn blasts and I can press the lock button. I'd like to get that fixed because it never happened with my 2011 and it is extremely annoying.
However for the topic at hand, the OP's dealer needs a lesson on common sense, since logically both FOBS can't go bad at the same. It can only be something common to the two remotes - and that would be the vehicle's FOB receiver, which is located above the headliner in the left rear corner of the vehicle, or it's associated wiring.
And, since a receiver replacement necessitates replacing the FOBs as well (you can't reprogram the FOBs once they are mated to a receiver), if you don't already have it, and considering that it is a function of the receiver that they are about to change in any case you just might want to ask how much extra they might charge to put in the remote start version of the receiver (the function is implemented in that module) and enable it with the appropriate sales code. After all it is very cold this year up here in Canada and having remote start might be a good thing to have.

Lastly, if you plan to hang on to the vehicle you might also want to consider buying an extended warranty from Chrysler (DO NOT BUY AFTERMARKET), since, as you have been experiencing, troubleshooting these electronic problems can be hit or miss, with the dealers having a less than stellar record of hits and they expect YOU to pay for the misses.

actually, no!!! well, not for certain, depends on your manufacturing date. They upgraded the front brake size in mid 2012. I have a 2012, and had to use the x44753 17" rims. The dealer had not checked, and sold me winter tires on the older model rims, and when winter came, they didn't fit. they had to change the rims for the x44753.
I recommend you have the dealer check your VIN number and confirm if you have the small brakes, or large brakes....

If you feel that you are being duped then take it somewhere else to get it checked out or inspected....just don't mention the dealer said they need to be replaced. Oh and have the warranty work done first by the dealer!
