I've noticed this issue start a few days ago. When trying to lock or unlock my 05' MDX from the remote, all necessary lights flash but the doors don't unlock. When I lock/unlock the doors using the switch on drivers side door, all doors lock/unlock perfectly fine. Any solutions?

 

Also, when the driver side door is open and if I then use the remote to open the other doors, all the other doors unlock aswell

 

cheap fix first
try changing the battery on the remote
might be low in power to fully function
