Replacement Key on 1999 Ford Explorer

I lost my spare key and need a replacement. I had one made at Home Depot, but I don't think it is the correct type. Do I have to go through a dealer to have a replacement made?

if it has a security chip, yes. most of them have one. it is not that bad. go to the parts department and have them make it for you then service will program it.

I have found a mobile local locksmith that has the equipment to make and program PATS keys. It saves a tow bill.
Thanks for your help!
Just a quick note - it says you lost your spare key. Does this mean you have two working keys?

If so, you can program the spare on your own. There is a procedure for that. If you respond to this that you have two keys PLUS your new spare, I will post it.
I only have one working key. When I bought the car I received 2 working keys, 1 to use all the time and 1 spare. I lost the spare, so I don't think your procedure would work for me. Thanks, though!
