Hello, I just purchased a used 2006 Explorer - got an amazing price (I think) thanks to the current financial crisis! I expect to have a bunch of questions as I learn about the car, but a couple of questions need an immediate answer. Note that I did search before asking my questions, but could not find an answer specific to my question. I only received one key and one remote control for the car, and definitely think it is smart to have a spares. Does the ignition key have a special built-in security chip or is the key one of the "plain Jane" variety that I can have copied at any lock smith? If there is a chip, does this mean that I have to buy my 2nd key at the dealer or is there another source? As for the remote control, according to the manual this doesn't look like a problem and I believe I should find one on eBay!
