There is a sensor on the back side of the tumblers in your ignition switch. This is the pass key sensor. Its bad. Have your switch replaced. Don't let anyone try to trouble shoot this. I have had to replace about 125 of these and they always crank and run afterward. Hope this helps. Good luck.

SOURCE: when I try to start
If any of the gauges are blinking and going haywire and the security light flashing then the instument cluster is faulty.But if it is just the security light flashing then its in the switch.If you only had the switch replaced then you need a new ignition lock cylinder because its worn out.

SOURCE: car won't start security light
If the security light is blinking, then the security system is DEFINATELY the reason why your car won't start. The actual cause of the problem is MOST LIKELY a defective ignition switch that is not sending the information from your key to the computer.
FIRST try a different key if you have more than one for the vehicle. I have had cars towed into my shop simply because someone was trying to use a cheap duplicate key that was cut at the hardware store. These keys are fine for the doors and trunk. They are great to have around in case you lock your keys in your car. However, they do not have the electronics built into them to allow for engine starting.
If you are using the correct key and a second key also does not work. then...
1. set your parking brake (this will disable your daytime running lamps and conserve battery power.)
2. Connect a battery charger to the vehicle battery if you have one, or see if someone can connect to your battery with jumper cables.
3. Turn the ignition to the START position for about one second. Then release the key to the RUN position. DO NOT turn the ignition OFF.
4. Wait about 10 minutes until the security light quits flashing. Turn the key (without turning it off) to the START position again. The engine should start. If it does not, then you will have to get your car towed in for service.
HINT: you may want to try this a couple times to make sure you are doing it correctly before towing.
If it does start, it is recommended that you have your security system checked for fault codes. I have seen this many times, and it only gets worse and does it more often until this method no longer works to get it started.

The process for the passlock relearn is correct. If by chance the relearn does not work, you may have a fail component in the system. Go to this link for options to fix this yourself.
