2002 Olds Alero. Dash security light. I replaced
ignition module. 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 lock cylinder, which
is also called the Passlock Sensor. Here is a pic of
the release tab on the ignition switch. Remove the
radio to access this.
Oldsmobile Alero Radio Locked
2001 Oldsmobile Alero. My battery cable came off. When it was
replaced, the radio is now locked. When it was put back on, the
radio is now locked and Says LOC.
On this vehicle and system, there are no radio codes to enter.
The radio should not lock up after a battery disconnect. The
system uses the VIN of the car for radio theft security. The loose
connection at the battery may have caused a malfunction in the
radio and needs to be diagnosed with a scanner. The radio Theft
on this system must be re-learned through the dealer scanner if
locked. Radio Unlock Codes.
2002 Oldsmobile Alero.
Removed old blown engine new fuel assembly many new items to
be exact. Has after market radio.I am wondering if and I hope I
don't sound completely ignorant. But do I need to bring the car to
a dealership with a new stock stereo and have them program it
all? It at this time gas an after market deck. Could doing this
replacement work if its gets programed?
Yes, is you install a new factory radio, you will need to get it
programmed for your Oldsmobile. Also the theft will need to be
learned or disabled. If you do not do these things, the radio will
Be sure to get the correct radio for your car. Do not just get a GM
factory radio. Many people do that and think it will work because it
is a factory unit. But that is not the case. It MUST be for your
model and year Alero or you will have nothing but trouble trying to
get it to program and work properly. Expect to pay 1 hour labor
charge to have that service done.

OK. Your are going to need to check to see if the spark plugs are
How will I know if they are firing?
You are going to have to remove a plug wire from the ignition coils,
crank engine and see if spark jumps from coil.
Where is that located?
The ignition coils are on the top rear of the motor. All 6 spark plug
wires plug into it.
After that should I give it a jump or try starting my car.
Is the battery dead?
No BC my car cranking.
Then you dont need a jump. Just crank it and look for the spark.
BE CAREFUL- do not touch anything metal while doing this.
So just lift the hood crank my car n see if the plugs spark?
Remove a plug wire from the coils and look for spark.
OK thanks please standby for further assistance .
Its raining out. Is it still safe for me to do it?
OK I'm walking to my car now don't go anywhere. Is it a good thing
if I c sparks?
If you see spark, then the computer is trying to start the car. Next
you would need to get the fuel pressure checked. You may have
bad fuel pump.
