Default Code help, intermittent starting

I've been having trouble with intermittent starting.

The codes I'm getting is P1631, (Theft Deterrent system password incorrect)

and B2721 (Pass key detection circuit. )


Can anyone shed any light on these bad boys?

Thanks,

I'd start with trying to clean the pellet on your key or try your spare key. If that doesn't do it you may need a new ignition cylinder.

I'm in the process now of troubleshooting from the clutch safety switch, ignition switch to the starter.

I just wondered about the theft deterrent password code, the password part most of all. WTH is that?

I had the VAT's turned off but it's still doing it. The intermittent starting thing is driving me crazy...It hasn't left me stranded yet, but I'm starting to worry..

I never heard of anyone turning off their VAT...do you use LS1 Edit for that and why would you want it off...just curious? You either got a dirty/defective pellet on your key or the ignition cylinder needs replacing.
