First, all button start cars start witout a battery in the remote; you can dislodge a physical mini-key from the remote and unlock the doors with it, and you can hold the whole (unpowered) remote directly near the start button and press it. Both parts usually work without a problem; aside from that, you could have replaced the battery for some cents.
In other words, If your problem was really only a battery in the remote, there was no towing necessary. Their point of view is probably that you produced that cost by 'not knowing how to use the car correctly' (not reading the manual and therefore not knowing above techniques). It might be annoying to you, but I tend to agree with this view, and you will have little chance legally to win such a battle.
It is a bit stupid from them to not tell you how to do it on the phone, but maybe the problem wasn't clear to them, of the guy on the phone didn't know either.
You might be able to sweettalk them into covering it, but this is probably not a good time to hope for lenience, as all car rental companies are bleeding badly for cash.
