You could try restarting the processor in the remote. To do this, remove the remote battery, and insert it reverse polarity (wrong way up) for 2-3 seconds, and then put it back in the right way.

I am also having similar issues. Bought a batch of 2032 lithium batteries but little to no improvement. Bought some duracell batteries to see the difference, none seen. However, followed instructions about reversing polarity and soon after remote works fine. Unfortunately, only works a couple of times and then fails to respond. Reverses polarity again, tries again and is working again, for a short while. Now fails to respond.
I cant seem to keep it working effectively. It is so frustrating AGHHHH!
