Wirless Key Remote

I have a 2002 Sienna and both wireless key remotes quit working. I changed batteries in both and they still don't work. Any ideas where I go next. Dealer wants $100 to check it out. :frown:

If you happen to have any other electrical bugs, they may be related by the wiring harness they share...a break, short-circuit, or bad ground. Otherwise, $100 isn't unreasonable to diagnose and fix. Let us know what happens...good luck!
