2014 Limited Factory Remote Start Issues

For the past 7 years my factory remote start has worked perfectly. I could remote start the vehicle from a hotel room approx. 200 feet away from the vehicle, as well as from a few feet from it. About 6 months ago it’s become almost inoperable. If I continue to rapid press the FOB remote start button if I’m within 25 feet or so it might start, but most of the time nothing, no light flashes or anything.

Remote locking and unlocking the vehicle has also become more unreliable, even when standing right next to the vehicle, but it’s no where near as bad as the remote start.

I have two FOBs, both with fresh batteries (I’ve tried multiple sets), and they both act the same.

So I’m thinking it’s more than likely an issue with the antenna(s), but I can’t seem to find any definitive info as to where those antennas are in a 2014 Limited 5.7 Hemi, or how to troubleshoot them.

Can anyone point me in the right direction?

Look at the posts from Agang4. It's cheap (free), quick, and worked perfectly for me. I had exactly the same issues.

Thanks, I’ll give it a shot.
