No I don't think they are the same but to double check call autozone or o'reillys auto

Here are two methods to reset the anti-theft system on 2007 Chevy Malibu:
1st method
1. Put the ignition in on position, let it breathe for 10 minutes, and remove it when the anti-theft system light stops blinking.
2. Crank up the engine; it should now start
2nd method
• While outside the car, press and hold the lock and unlock button together
• Let go when the car honks and the lights flash
• Put the key in the ignition and rotate to the ON position, and leave there for 30 seconds
• Switch on the car, and the anti-theft system would have reset

There may be a problem with your ANTI THEFT SYSTEM. Have it checked out before it leaves you stranded somewhere.

anti theft system light blinks car won't start, crankes but won't start help?

I just had this to happen to me - here's what you do - when it will not crank - turn your key over to ACC and let it stay on here for 15 minutes, the THEFT SYSTEM light will stop flashing. Turn your key back to OFF then turn it over as normal when starting and it will start right back up! Found it out from an auto store! One lady paid over $700 and then found this out!!!
