if you have a manual transmission all you need to do is replace whatever it is your goin to replace(like your radio) and let the car stall out, sit in the car for 15 minutes and DONT TOUCH ANYTHING. play a gameboy or eat a sandwich and wait the whole fifteen minutes...after the time is up try and start your car again, the theftlock system should run the computer codes through your BCM and walla! your theftlock is now gone!

Well it depends on what you are trying to do, I changed the tumbler in my car and i couldn't get it started because of the anti theift. what i had to do was try to start the car, than the anti theift would shut the car off. you wait ten min with the key on, until you see the anti theift flash or disapear. than turn key to off position and try to start it. this will reprogram the computer.. Good luck.
