I have 2002 avalanche and I replaced the ignition key module and the cylinder and also have tried the 30 minute reset security for key with no luck. But what is happening with the key off and out the tell taale screen shows the battery a few times then flashes security a few times and keeps going back and forth and has not stoped yet. Did I over look something or is this another problem thank you for your help
