MikeH,
Thanks for the info. I was able to pop off that paneling today and locate the module. I copied down the code into the owners manual to prevent any further problems like this.
Also, went back to the GM dealership were we purchased the Explorer, they are willing to refund us the amount it will cost to get a second key and what ever it costs for the programming since there was a bunch of stuff we caught them in lies about.
Thanks again for everyones input,
Brian
