Purchased a 2500HD (2 weeks old), traded a 2018 1500 BigHorn, BigHorn factory installed remote worked flawless since purchased. I had the dealership install the factory remote prior to the 2500 delivery (Hemi) - first time used doors would not un-lock I had to use the key - found what others have, multiple taps will open - key will open / engine stops - sometimes it will work first time - does not matter if it is the new key fobs or the ones without remote - all will operate the same / had the same issues, if you allow it to run / time out, the doors will open with remote no issue - called dealer told to bring it in, worked on it for an hour came out and said they just received notification from Mopar, Mopar advised in writing they were aware of the problem and expected a correction, gave me a case number and letter from Mopar that a TSB software update will be released during the 2nd quarter of 2021 - in bold print it states: "Replacement of RFH, Fobik's or any other components WILL NOT resolve this customer concern". The dealer then advised they will stay on them and when resolution is available they will notify us. From what I have read here, Sounds like it may be awhile.....
