Remote not working for Nikon D70. Any ideas?

I've got a standard ML-L3 remote for my D70, which I have used for years without issue. It stopped working, so I replaced the battery. No dice. Just received a new remote and it doesn't work, either.

I'm probably stuck with taking it to a shop, but are there any thoughts as to why the camera is no longer responding?

Yes, I've ensured the camera was set for the remote.

Thanks in advance!

Unfortunately you have narrowed it down to the most expensive part. Good luck.
