If you didn't have the problem before getting the key fobs/programming and all other functions on that fuse still work fine that might be where to look.
Parasitic draw from fuse #14
I recently purchased a 2009 2.7L Charger and I'm having an issue with a 1.1 amp parasitic draw that is coming from fuse 14. I have been fixing/upgrading things since I purchased the vehicle so it's been difficult to figure out what's causing the problem. I installed an aftermarket head unit and back up camera. Those were my first guesses, but the camera doesn't draw anything and the radio draws 50 mA. I purchased 2 key fobs and had them programmed at a local locksmith. I see fuse #14 deals with the instrument cluster, keyless entry, and HVAC controls. I have narrowed it down to that circuit but I'm unsure as to where to go from here. Through the search function I found other people with the same problem on this forum, but nobody has an answer. Has anyone solved this problem before I tear the whole car apart?

That's what I'm thinking too, but I don't know how that system works. Is there a module or something that could be bad? I'm just not sure what to look for.
Might want to ask the locksmith who did it.
Have you disconnected the battery for 30 minutes to reset everything to see if the issue goes away?
Yes I have disconnected the battery overnight. When it is reconnected the problem remains.
Keep us posted on the fix. On the 06 R/T, the parasitic draw was first blamed on the stack, then the dvd player in the console for the rear seat. Never really got to the bottom of it. We turn the headlight switch to OFF vs DDRL/Auto and the problem went away.
When you are referring to fuse #14, are you talking about #14 in the REAR power distribution box in the trunk? If so, in addition to AC Heater control and the Cluster, it also pertains to Sentry Key Remote Keyless Entry Module. The fact that you had to have 2 new keys re-programmed, was there an issue with the old ones being recognized? You may want to focus on that module as a possible culprit.
Just seems like the one of the modules is not going to sleep like it is supposed to. Seems strange that reprogramming a few FOB's led to this, but I would disconnect the security module and see if the drain stops.
Yes it is fuse #14 in the trunk. I did some more tests today. I disconnected the A/C Heater controls and it still pulled 1.1 Amp. I pulled the instrument cluster out, unplugged the 3 plugs in the back, and the draw went down to 50 mA. I'm guessing there's something wrong with the instrument cluster? I emailed a couple repair shops that test/rebuild instrument clusters to see if this is something they can fix.
Update: I sent the instrument cluster out to be tested for a draw. It came back with nothing wrong so that's not my problem. I'm still trying to figure it out.
