I have the opportunity to purchase a clean 2004 Pontiac Grand AM for a really good price.
My concern is that it had issues with the Passlock system in the past; the security light was on constantly. The owner said he never had issues starting the car. However, a few weeks ago he cleaned the connections on some of the control modules. After cleaning them the car would not turn over. He did a security system relearn, the car started, and the light is now out.
I read this can be an easy fix. I’ve also read that once Passlock starts acting up, it starts to get worse.
Anyone have experience with this system? A good way to bypass it entirely, perhaps install a remote start? Should I run the other way?
