Car: 2006 Dodge Magnum SRT8
Mileage: 192K
New wheels and tires installed: August 2018, 181K miles, all new TPMS sensors installed

On Tuesday afternoon when I went to leave work, I noticed that my key fob didn't work until I was really close to my car. Later that evening after the gym, it worked at it's "normal" distance. I assumed that the battery was dying, so I just chalked it up that I would need to replace it soon.
Yesterday (Wednesday), just as I arrived to work I got a flashing tire pressure warning light, with "Check TPMS System" error. Flipping through the EVIC, the Left Rear showed '--'. After I parked, I check the tire and it wasn't flat. So I assumed that the Sensor was going bad. When I left to go to lunch, same error message but both the rear tires showed '--'. When I pulled into the parking lot at work, both rears and the right front went '--'. By the time I parked, the right front started reading but both rears showed '--'.
While at work, I researched on these lovely forums and saw issues relating to the Wireless Control Module as being a possible culprit (thanks to my keyfob issues happening as well. (https://www.lxforums.com/board/gene...else-3.html?highlight=Wireless+Control+Module) .
This morning, as soon as I started up the Check TPMS error came on. Today, only the Right Front has been showing '--'. The distance at which my keyfob works is intermittent. If the car has sat long (overnight, during work), it will work at the normal distance. But after driving it (to work, the gym), it won't work at all and I manually lock the car.
This afternoon I did the second "reset" found in that thread. I disconnected the battery for a minute, reconnected it, placed the key in the ignition and pulled the Ignition Off Draw fuse (#1 in the rear fuse box). I pulled it for a minute and then replaced it. Turned the car back on and still the same Check TPMS error.
The car has yet to strand me as some of them have done. At this point based on my troubleshooting, I believe that my Wireless Control Module (WCM) is on it's way out. For all you LX elecrtrical gurus, does that sound like a safe assumption? Is there anything else that you can recommend I do to try and reset the WCM before I make the call to the dealer to have them order the part. I know that the new WCM will have to be programmed to my car (and my keys updated as well), but I want to exhaust all options before going the replacement route.
Thanks for your help.

I read through this thread and figured that when I got home last night I would attempt the disconnect battery reset. I disconnected the battery for 25 minutes. I reinstalled the battery cable, restarted the car and no error message. It was late and I didn't go for a test drive, I was tired.
