Every once in a while the security light on my malibu comes on and the
car will not start - we input the key to the ingnition wait 10 minutes then the car will start. This does not happen every time - just every once in a while. Does anyone know a way to fix this problem?

Re: 2002 CHEV MALIBU - SECURITY SYSTEM
The car has a built in security theft lock, what yours is doing is loosing the key, so when you put your key in it thinks it is being stolen, by leaving the ignition on for a period of time you are allowing the computer to recognize the key, often you can solve this problem by going to your chevy dealer and having a new factory key made, usually costs less than $10

1 Diagnostic System Check (requires scanner)
2 Transmitter Test (requires transmitter tester)
Most times if lock/unlock works correctly from interior switches
problem is transmitter.
IT CAN BE TESTED with J 43241 Keyless Entry Tester.
This is most times only found at larger GM dealerships.
Take it into parts department and ask to be tested before
replacement. BE SURE THEY HAVE THE TESTER.
smaller dealerships very often do not.
If it tests good, Diagnostic System Check is required.
It sounds like you might be having an issue with the transponder or "chip" in that key. When you turn the key and it doesn't start you probably see a flashing key icon on the dash with a circle and a line through it. When you remote start the car it is using a by pass module to trick the car into thinking you have a valid transponder key in the ignition when it starts up. Go to a locksmith and have another key cut and programmed to the car.
the manual says to put the key in the ignition, turn on all the way, but don't start the car and leave for 10 minutes until the theft light stops flashing. turn off all the way and star it up. good luck.
A couple things here. It is best to have a "tach wire" and the system needs to be programmed to learn the tach signal in order to know if the car is running or high reving or dead. If it gets no signal of the sort the next option is voltage monitor, it monitors the voltage for an increase to show that the alternator is running. Either way that signal is not gettting to the viper brain or it has not learned that signal. You need an install manual, did you install the alarm?
