Hey, everyone. I have a 2013 ML350 BT. The factory battery finally gave out right around 100,000 miles after my wife left the lights on by mistake for four hours. Couldn't jump it so I bought a new battery and installed it, without a memory saver, figuring I just needed to reset radio presets, seat presets, and bluetooth connections, etc. Swapped out the battery and everything works great except the drivers side front door lock is working the opposite of the button I hot on the fob. all other locks and fob functions work perfectly. i removed the battery from the fob and replaced it - didnt fix it. I tried the open/close for 10 seconds thing I saw online, didnt do anything. saw another suggestion to put the key in the ignition, hold the door lock button, remove key, hit unlock button 5 times while still holding lock button - nothing works. Went in the vehicle settings menu and reset factory settings - nothing. Help!?! Want to avoid the dealership at all costs...

 

oh, I have exactly the same problem after my car run out of battery few days back. Still didn't get any idea to solve it...
