just recently bought my mustang from an auction house but it only came with one key. My key has a transistor in it and I wanted to get it copied but it costs like $75+ to get it copied. If I buy my own blank transistor key online is there a store that will copy it for me for cheaper?

 

Since you only have one key, you only have two choices for getting the key programmed to the car. Dealer or locksmith. You could buy a blank key online and get it cut, but it will not start the car.

 

I just did the same thing. I only got one key with the car, so I have to go to the dealer to get it cut and have it programed. It cost me $98.00. Don't the key from the dealer for 35-45 bucks when you can buy one on E-bay for around $14.00 hope this helps. Jerry

Read the above again....

I don't remember exactly which year it changed (98, 99 maybe), but for an 04 you need 2 working keys to do it yourself; with only 1 working key, you have to have a special doodad to program a key to the car.
So call around to some dealers and locksmiths and ask them how much to program a key that you provide as opposed to them providing the key also.

 

I bought 2 of these from Ikeyless for under $13 shipped. Had a mobile locksmith cut and program for $65. I also got 2 fobs from Discount Keyless for about $10 shipped. Got both programmed in about 2 minutes. http://www.amazon.com/gp/offer-listi...&condition=new

 

Iv'e heard for some of the older cars, Advanced Auto could help you out. Either that, or as mentioned, buy a cheap key off ebay and have the dealership program it.
