When you say it wont start the car. Are you saying the engine wont start & run or stay running?

Will the key go in the ignition ok?
Will the key turn the ignition?
Will the engine turn over or crank temporarily?
Will the key unlock the door(s)?

As Ray noted, you may need a key with a chip in it.

Now, you key saying; "Key with a little car & lock symbol". Ok, so did you get more than one key? Did one key start the car but the other key wont?

Ahhh... ok, so you unplugged some things under the dash including the anti-theft device & now it wont start?

So, did you get the anti-theft device plugged back in ok?
If so, I am guessing its going to have to be reset by a computer code at the dealer. I don't know that but thats what I'm betting.
Hopefully someone else has idea's & or knowledge.

Good luck.

The new chipped key must be learned into the car's computer. For you to do it..... you'll need one working key and the new key. If you don't have a working key then the new ones must be dealer programmed into the car.

Your security system does not recognize the key.
This is why you have KEY symbol showing.
You need to do key learning procedure or have dealer mate key to computer.
Otherwise, you have fuel pump disabled.
We have no idea what and WHY you disconnected under the dash. You might as well messed something up.
