Like many others I too have a the dreaded "security light" no-start issue. I know the problem is caused by the chip in the key not being picked up by the lock cylinder, but I'm wondering how much and exactly what parts are needed to correct the issue. Of all the posts about it, no one seems to say what they did to actually fix it. The two relevant codes I'm getting are:
B2721 PASS-Key Detection Circuit
P1631 Theft Deterrent System Password Incorrect
It's been happening randomly for over a year but started happening daily in the past week as the weather got dramatically warmer. It's a '98 and I only have one key. I'd be grateful if anyone has successfully resolved this and knows the fastest way to approach the repair.
GM and their shoddy electronics strike again - this is incredibly frustrating!! :bash
