If the vehicle starts an drives, even at 40 to 50 miles per hour the anti-theft system has nothing to do with this. The PATS anti-theft system on that vehicle disables the starter from working to deterrer vehicle theft, that's it.

overdrive light blinks ?? you have a transmission problem with the electronics .With over drive light blinking codes are stored in the computer . Need to hook up a professional grade scan tool an check for codes . Your best bet take it to a qualified repair shop that knows what it's doing.

Have you tried fuse for dashboard

Is the security light on or flashing when trying to start the vehicle .
Anti-Theft The passive anti-theft system (PATS) consists of the following components:

• Anti-theft indicator
• Encoded ignition key(s) (the key contains a transponder)
• PATS transceiver
• Powertrain control module (PCM)

PATS will disable the vehicle from starting if there is:

• a damaged PATS key.
• an unprogrammed PATS key.
• a non-encoded key (a conventional key or one that does not have any electronics).
• damaged wiring.
• a damaged transceiver.
• a damaged PCM.

If it is a anti-theft system you will have to take it to the dealer .This system will keep the starter from spinning the engine .

If you have a second key, try that one. Sometimes 1 key will unlock, 1 key will start. If not it would be the anti theft or security system disabling the ignition module. Which is why it won't even try to turn over.

Sounds like your anti theft system is kicking in. Is your anti theft light blinking or on?

Some months ago I began starting the engine of my 2001 Chrysler 300M but turned it of before it really started "was sloppy with the key". The anti-theft system went on for some unknown reason. I disarmed it by disconnecting one of the battery connections under the hood with a wrench. I connected it again, the anti-theft system was off but the battery was dead. Battery was OK after recharging, I have had no trouble since then.
