Question about 2003 Chevrolet Monte Carlo
Did you disconnect the battery when you did this, because if you did, the security key information may have been lost. This happens in some GM and Ford vehicles, as well as Chrysler.
You should take the key and vehicle to the dealer, where they can help you reprogram the key(s) you have to work with your car's ecm or security system combination.
Sorry, about that.
Sometimes, it pays to go to Walmart and get a 9volt battery memory keeper when disconnecting the main battery, so that it will not lose memory, if that's what happened to you.
It's not costly to get this, like less than $5 for the memory keeper, in my area, anyway.
Good luck on this one.
