Your spare key probably isn't programmed for the car. Ford uses a stupid chip in the keys. I have the same issue with my Explorer. You have to buy a key from the dealer and have them program it for you. About $50-75. (Ford owns Land Rover, in case you were wondering)

My 2005 dodge neon sxt will start but it shuts off right after it starts even if i hold the gas pedal down

I post this as a serious answer.... As simple as this might sound, but are you using a spare key in the ignition that's not chipped, by chance?? This sounds like what the car will do if you attempt to use a key without the security chip (I know bc I had to try it one time to see what it would do.). But, if you are, and if you've tried more than such a number of times, it will lock out the computer and the dealer will have to reprogram it for you.
Otherwise, if it's a mechanical problem, good luck, I'm not sure what that may be, offhand.

Disconnect the Positive Battery Cable.
Open the Drivers Door & Leave Open.
Turn Ignition Switch to ON Position (run)
Reconnect Positive Battery Cable.
Horn may sound for a few seconds.

Good luck!
