My 2010 Dodge Challenger R/T a week ago started beeping when I walked up next to it without me pressing the key fob, I thought well that’s weird and decided maybe the key fob battery was low so I replaced it with a new battery and no change, still beeps unless I manually lock it from the inside and shut the door doesn’t beep. Has anyone heard of this before? I have video of it but can’t figure out how to attach it to this thread.

I’ve replaced the battery 9 months ago with a more expensive gel battery made for cold weather and longevity so I don’t think it’s the battery

check your cars actual battery level. This 'can be' an indicator of low volt.
also: if batt level is good to go on both fob & car batt. try a batt disconnect (both cables wait 5 mins, reconnect) this will reboot the ATS. Finally, just because a fob batt was "new" unopened in package, does NOT mean it was actually still good. Ive bought brand new batts that were all but dead.

It's the car horn beeping? Do the doors also lock when this happens?

I took it to get the battery checked and it’s running at full amps. When I turned the car off it locked me in it and before three times. It has something to do with the alarm system but I don’t know what.

Beeped

It’s seems to be auto locking itself, it locked me in the car today when I turned it off

Do you have more than the one fob? If so, I'd try the other one and see if the same issue. It's beeping because beep when locked is on (I assume), so the issue does seem to be it's locking when you approach, and randomly (or when you shut the car off?)

No I don’t, and ask of the above, when I turned the car off it locked immediately by itself and I had to unlock it to get out and as I was getting out it was already relocking and armed itself and continued to auto arm itself

With another car that developed the habit of locking the doors at semi random times but stil confined to shortly after driving off from a cold start, or when I locked the car again at random times the horn would beep like there was a door ajar but there never was, and one more odd behavior which you have not reported but my car's passenger window would not drop when the door was opened using either handle. But worse was sometimes it would drop when the door was opened just normal like but after a moment or two could go up again.

I may have suspected a bad key and tried the second key or suspected weak batteries and replaced them but I'm sure if I did I'm sure I'd remember if this helped.

The underlying problem turned out to be with a (passenger side) door lock controller.

Another reported cause of this and other odd behavior with the door locks and windows was water in the door.

However, the door bottoms were dry.

I took the car in for the symptoms. Tech read the codes from the security module which were inconclusive. He removed the door panel and checked mechanical linkages and found them good then did some more tests and confirmed it was the door lock controller and not the door handle switch or door latch switch.

After the new door lock controller all the horn beeping, self locking, and weird window behavior was gone.
