Vehicle make/model = Olds Alero
Year = 2002
Mileage = 127000
Engine size = 2.2
dash lights = security light
work done to repair = replaced ignition module
tip/donation yes
tech = JK
question = The car was working fine and the radio was left on while I
was in the car. When I went to start it, it wouldn't start. After
letting it sit for awhile it finally started. We had it tested for codes
and non came up. We replaced the ignition module and it started right
up. Now it won't start again. I have read about this problem from other
people on here and it seems as though it may be the ignition cylinder
is bad. I saw where you told a person you would send them some
information on how to replace this. Is that something you could also send to
me? I would really appreciate it and an email would be the best way so
I could have it quickly.

Thanks for the tip/donation.
It does sound like the ignition cylinder is bad. This is the most common
thing to fail for a no start, and security light. A faulty Body Contol Module
(BCM) is a slim possibility, but no real way to test it without a scanner that
can read module data, and a volt / ohm meter. This is also assuming you
do not have a non-factory alarm or remote start on the car. These cause
problems with the factory system.
To replace the Passlock cylinder, basically you need to remove the plastic
trim around the radio and the a/c heater control head by prying around it to
release the retainer clips. Be careful not to break the trim, then remove the
radio. Now you can access the ignition switch and cylinder assm. You need
to remove the cylinder from the ignition switch by turning the key to the ON
position. There is a small opening in the housing that you need to stick a
small pick or screwdriver into to depress the ignition cylinder release tab.
Then the cylinder can be pulled out by pulling the key and cylinder out
together.
The new cylinder will need to be coded to your ignition key before
installation. After all is re-assembled, the system will need to be re-learned.
