Problem on my 1996 Pontiac Bonneville
3800 V6 non turbo
security light
Repair done= removed keyless starter remote starter and key
security was locking me out for days on end would start when it felt like
starting
tech = jk
question = why does my security keep locking me out
will not identify key
this thing has a mind of its own
will start when it feels like it
it will work fine for weeks on end
and all of a sudden you cant start it
for hours or days security light
some times blinks and some times steady ?






JK:
This sounds like the common problem with the passkey security system. A
common  problem is the 2 small wires on the ignition key cylinder break. This
causes a loss of key  data for the system. Sometimes tilting the wheel in different
positions will enable it to start  and give an indication of the broken wires. Click on
the link in  the website for 'How-to, tips, etc.' Then click on link to
'passkey ignition(chip-in key) cylinder'
for a good pic of the  ignition cylinder problem.

Theft / Security Light

The security system on todays cars and trucks prevents the vehicle from being stolen.
There are many variations of the system going back to the early 1990's.

This warning could be on when the engine is running, indicating a fault has been
detected in the system. If left unrepaired, there is a good posiblity that the car will
eventually not start.

There are several different possibilities for the cause of the warning, depending on the
make / model / year of the vehicle. Anything from a bad ignition cylinder wire, to a bad
cylinder to a dad Body Control Module (BCM).

After market (non-factory) alarm and remote start systems can cause havoc with the
factory theft system, causing this warning light, or a no start.
