Hey guys i've got a 2000 SS Camaro six speed, my security light was flashing an the car would not start. I changed the lock cylinder an when i pulled the old one, one of the white wires was broken....Well i put the new lock cylinder in an it started fine an i had no problems up until this last weekend(about a week after replacing it). I started the car an noticed the security light came on but shut off within a matter of 2 to 3 seconds, then the next time i went to start it the security light start flashing an now it wont start again

Before i tear into this again, i was wondering if there was any other things i could check first that might be the problem....The lock cylinder i put in was not a GM part, it was an off brand from O'reilly's could that have anything to do with it?
