The only way to bypass is to have your PCM custom reprogrammed. That'll cost more than it would cost to fix the root problem with your anti-theft system.

SOURCE: 2004 Buick Lesabre uses quart of oil in 3K miles. Is this normal?

No it's not have your engine check for oil leaks, also have then do a wet and dry cylinder compression test this will let you know if you are burning oil, also have them check the spark plug's.Hope this was helpful.

2004 Buick Park Avenue. How do I bypass the anti theft system please?

It is very difficult to bypass because the anti theft system and immobilizer is there to stop exactly what you are trying to do.

It is better to fix it rather than finding a way to defeat it. Have a read.
