Thank You Newrockies! I fixed my 1997 88 Oldsmobile by installing the Newrockies Passlock Bypass Pro Module! My security light kept flashing and my car would not start. That's the lowest feeling when you live out in the middle of no where, on top of a mountain in the National Forest. However I was able to fix the situation, without trouble shooting in pairs, other than a new battery. It was not the battery. Money wasted. Yet here I am with a running car, because I came across this website and took a chance at beating all odds I recommend you check this out if you're in the same situation or similar as I was. I'm thrilled for my successful self repair- permanent repair I should add. Five stars all the way (be prepared to work, it can take awhile if you have no clue what anything means as I didn't understand any of the instructions and it took me 3 days to finally get it installed. I had to basically find out what every word meant because I'm not mechanically inclined and didn't understand. For a long time I stared into the car, behind the glove box, looking at unknown parts, (to me) at multiple devices with dumbfounded awe and confusion, however if you understand cars and wires and stuff this is EASY) Thanks again Newrockies
