Doors Unlock after locked

[SJR25]

Hello. I own a 2017 Ram 1500.
After I lock doors (w/remote or w/door lock button on door, after about 10 seconds the doors unlock on their own, headlights come on and hazard lights quickly blink twice. The hazards continue to blink every few minutes. I cannot lock doors unless I disconnect battery. After market remote start (w/my key fob) was disconnected (thinking issue was because of remote start). Any suggestions would be greatly appreciated. Ty

I’d take the battery out of your key just to rule that out. Sounds like it’s acting like it’s being unlocked via key.

Pull the key FOB apart and make sure the little discs haven't come loose from the keypad inside and are floating around in there

Is there a key fob still in the vehicle. Sounds exactly like the safety system to keep you from locking your keys in the unit. If you lock it three times in a row and it doesnt open on the 4th it is the safety. Also, if you lock all the doors, open and exit the drivers and lock the drivers with the silver tab near the window it wont unlock even if your fob is in the vehicle.
