What key style does this product use? Is there a special fuel key that goes with it or would your ford mustang key work?

    2003 Mustang Gt... PERFECT FIT!

    I recently brought a 03 Gt.. and was concerned about Gas theft,..Etc. So i knew i needed to buy a Locking gas cap, but i heard generic after market gas caps can cause "engine light', or other issues. Then i remembered i had the same dilemma with my 08 Bullitt.. and was able to locate a Official locking cap - from Ford. So American Muscle was the only place i could find this Ford LGC for the 03 gt. It was a Perfect fit.. No issues... Works GREAT!

    Great product to place on your mustang! It gives you security knowing that no one steal your gas, and to put harmful, unwanted chemicals in your tank.

    Easy install

    Took me about 5 min to take off my stock fuel cap and replace it with this new lockable fuel cap made by Ford. Being a Motorcraft part I am sure it is a great product and works well. I got this fuel cap because my office for work isn't in the best neighborhood so just wanted to make sure no one looking to wreck my engine by placing harmful products into my fuel or someone trying to take my fuel, I bought this to have some peace at mind. Hope it works as well for you as it is for me. Thanks American Muscle.

    This gas cap is way better than one of those generic "fits all" caps you can get at the parts store. I was amazed that is an original Motorcraft part brand new in the box! HIghly recommend.

    Really nice

    Ordered this on 4/19 and I received it on 4/23. It is just like the factory gas cap except this has a hidden lock behind the ford logo on it. It's just awesome. Got this instead of the fuel door that has a lock which cost twice the price of this locking gas cap. So I saved some money lol. Now I can finally stop worrying about my baby every time I leave it in parking lots everywhere I go. Keeps the haters from ruining ur car. Lots of Hondas here in my area and they hate mustangs, I'm afraid they're gonna try something tricky on my stang lol. Very satisfied with this locking gas cap. Very sturdy too. It comes with 2 keys. thanks for added security.

    It was neat while it lasted

    This was really cool when I bought it. I don't know if it ever did anything for me, but it looked nice none the less. I would suggest keeping the key for this in your glove box or something, trying yo fit your whole keychain in to unlock this is kind of cumbersome. I say "while it lasted" because my car threw a fuel leak code a few weeks ago. Online they said check your gas cap, especially if it's aftermarket. I then checked the gas cap and it came off without even using the key. I put the stock one back on an code went away. For the cost of this cap, I expected better. I'm just going back to assuming no one will put random stuff in my gas tank for no reason.
