Keyless Entry Not Working consistently

When I use my key fob it always locks the doors but as far as unlocking, sometimes it works but other times doesn’t unlock all the doors. It seems to always unlock some of the doors but often won’t unlock one of them. The one it doesn’t unlock changes. Sometimes it’s the drivers door, sometimes it is the rear passenger door. Now it sometimes doesn’t beep when I lock it, but it is locking. Any idea what the issue could be?

 

Check the batteries lately?

I have aftermarket Amazon remotes, 2 for $20. Most of the time they work, sometimes they respond slowly. For me it’s 1 press for driver door, 2 presses for all doors but I heard there’s a way to change to 1 press for all, not sure how to do that part though.
