Sounds like the anti theft system is active m try this process. Turn the key on. Do not attempt to start. Wait 10 minutes. Turn key off. Turn key on. Wit for theft light to go off. Now attempt to start.

sounds like the battery disharged. If the key was on along with the lights than 20 minutes would be enough to drain the battery. Try a jump start. it should get you going. I would have the battery tested after driving for at least an hour at highway speeds just to make sure it is good.

Have you tried the reset method? Turn key to the ON position and leave it there for 10 minutes, or until the security light goes off. Then turn key to off, and back to on and start-see if it starts after letting it sit for a few minutes like that with the key in the on position.

Hello and welcome to FixYa!
Looks like that you have a failing IACV (idle air control valve). If the IACV is faulty, the vehicle tends not to start or may stall during operation. I suggest that you have the vehicle scanned to know exactly what the fault is. Though I suspect that it's the IACV.
Hope this helps and thank you for using FixYa! Have a good one!

yea got get you more troubles
just check the alternator is charging well and no battery light on dashboard it indicate the bad alternator
monitor your battery if it got old and cannot hold the charge any more
you said when you used another one your car turned on

Hi, a normal PATS response is slow blinking. Fast blinking indicates the transceiver is not reading the transponder. Can you tell me your model and year? I've had some success in bypassing PATS in the column, but it depends on the model and year.

The solution to my problem wasnt the recurity thing ,,,,,after a few calls and having to take it to the garage for repairs,,,HAD TO CHANGE REGULATOR-FUEL LINE FILTER AND FUEL PUMP ,,,Helpfull hint ,machanic tells me u should change the fuel line filter at least once a year if u use regular gas on a regular basses.It may help this from happening again.
The security thing works like this only if you think that is the problem,,,Turn key to ACC position and leave on for 20 minutes,Than shut key off for 10 minutes,after ten minutes try to start .Hope this helps someone thanks for any help.

I found this on a website try this

1. Put the newly cut Master key into the keyway and turn it to the ON (RUN) position. A "security" indicator
light on the dashboard will stay on for 10 minutes.
2. Within 1 minute after the indicator light goes off, turn the ignition to "OFF", then return to the ON (RUN)
position. The indicator light again will stay on for 10 minutes (Do not remove the key.)
3. Again, within 1 minute after the indicator light goes off, turn the ignition to "OFF", then return to the ON
(RUN) position. The indicator light again will stay on for 10 minutes. (Do not remove the key.)
4. When the light goes off the third time, the new key is programmed into the computer and will start
the car. Remove the key and then re-insert it into the ignition lock and start the car.
All previously stored codes will be erased. To stop the process at any time, simply remove the key and use
an existing key to start the car.
