uSED VEHICLE?
hAS THE steering lock been changed and the door/trunk were not changed?
Do you have the key code for the vehicle.
There is no key lock inhibit feature.
Thats stupid.

 

Okay, after wintering my GT-500 I found the battery dead, and I could not open the doors either with the fob or the actual key. (Funny I don't think I have used an actual key on one of my vehicles in years.)

1: I tried to use both keys in the doors turning in both directions.
2. Read the manual. (dosen't clearly mention this problem, but you can read
between the lines in several places about the anti-theft system.)
3:I read several similar forums of other people who this has happened to.
4. I called the Ford Customer service they had never heard of it.
5. Called Hefflen Ford service department. They said they had never heard
of the problem, and recommended a lock-out service from ford road side
assistance. (they didn't try to sell me a tow,
break my lock and sell me a new one. So, they seemed honest. First
number I called. )
6. I contemplated the universal key (brick) solution.
7. Talked to the woman at the call service. She had heard and said that it
had to do with anti-theft the car needs to see the key to work. This
prevents theft that relies on cutting the battery. Huh....Well, okay.
8. Tow guy came and we tried to open the door with one of those balloon
and hook devices. It there was actual pannel between the glass and
body this would have worked. Almost broke the glass.
9. We discussed popping the hood just to jump it.

Here is the solution on the 2012 Mustang.

10. We popped the hood from the outside. After we tinkered with it, and he
was the one who actually let the hood lose, the rest was simple.

If you have the hood open on this mustang you can see how easy it is to do.

You can just reach through the diamond grill work and actuate the latch. It's pretty easy once you see how it is done.

Now I have a battery conditioner for my long storage periods.

For others I hope this helps. Yes it is true. The doors can lock and keys not work. You can pop the hood on the 2012 GT-500 from the outside. They jump or charge.

Simple after that. Interesting learning experience.

This may be a design flaw, but it has a go around. Even if not many people know it. I tripped over it.

WD-40 is the worst thing to introduce into your lock mechanism.
Powered Graphite is the thing to use.
The WD-40 will 'dry up' and leave a sticky residue that will
kill your locks.
WD-40 is only good for weighing down your trash
can to prevent it from blowing away.
A quick pull on the release cables outer jacket from under the
front grill will release the hood lickety split.

 

I hate key fobs. I don't even carry the fob for my SUV (my DD) and as far as the Stang, the fob is on the key chain just to help me FIND those keys when I decide to drive it. Darned things are more trouble than they're worth and take up too much room.
