Radio and Keyless Entry don't work

He other day, my 2000 Venture's keyless entry pad didn't work. When we open the door (via the old fashion way - the key) and started the van, the radio doesn't work. Any idea if these two can be related or just very coincidental? And any suggestions on how to fix it myself?
Thanks!

Anyone have any thoughts? Thanks!

Sounds like a security issue. Some of these vehicles will lock out some of the electronics (e.g. radio, keyfob, etc.) and could be that somehow yours got reset. Unfortunately this is my first day with a Venture, my G-30 having gone comatose. Check the owner's manual to see if it has a procedure for resetting security codes.
