Remote for 2000 Honda Odyssey does not open or close sliders

Our remote for our 2000 Honda Odyssey does not open or close the sliders.

We are not sure when this began.

The front door locking with the remote works fine.

I tried taking the battery out and putting it back in, nothing.

Is there anything we can do? We don’t want to spend 75 bucks on a new remote.

Thanks.
