We only have one set of keys for my 2007 Mustang. Does anybody know the best (ie. cheapest) way to get new sets of keys and the electronic key fobs made?

 

if you have a set of keys that would be a pair since we only have 1 key for doors,trunk and the ignition
try ebay for a blank thenhave it cut by a locksmith program per owners manual

 

Fleebay has both fobs and blank keys. Get the RIGHT ONES. Try locksmithsource as a starter.
Then have em cut locally by a LOCKSMITH. If he wrecks it he will REPLACE it. Not true of Home Depot or k-Mart. For the fob make sure you get one with the right FCCID. Got several for a few bucks for my son's 05.BIGHANK

 

What is the FCCID and how do I get a FOB with the right one?

 

FCC ID => Federal Communications Commission Identification

Should be on the back or inside cover of your current FOB

 

Is it true that I will need two keys to get extra keys made? I have read that you cannot just have a single key and get new keys cut and programmed.

 

NOPE
I got an additional key CUT using one of the originals. I don't remember but YOU MAY NEED 2 KEYS to program the new key to the car.[8D]BIGHANK

 

At the Ford dealership I worked at they could program a key as long as they had one key that worked. Your best bet would be to find one cheap online, maybe eBay and then get it cut/programed at the dealership. You can check the dealership prices for the key also but it's probably going to be expensive.

 

I locked my keys in the trunk at the airport and if my roomate hadnt brought my spare set out to me when I got back it was going to cost me 250 bucks to have a locksmith fabricate one from scratch on site so expensive

 

As long as you have one original, they can cut you a new key. I did this with my 2006 Focus. I purchased an extra key and a FOB from Ford. I'm getting a locksmith to program the FOB for about $20.00, which is better than Ford wanting $80.00.
