Howard, did radio display show "CODE"? If so, then the anti-theft was set when the battery went dead, and you'll need to have it input, or changed. If not, there may be something else goin on. Hope yer guy gets ya fixed up! Let us know what he does to fix it.
I've got a website bookmarked on my puter at the shop, that will tell you how to reset security codes for radios of just about every manufacturer...but ya hafta PAY for the info each time....
