2004 Chevy Impala - no response after key security delay

Electrical problem
2004 Chevy Impala We have plenty of battery power on our Impala. The key start has two audible delay signals. After receiveing the signals, the engine has No response, just a disappointing spongy feel of turning the key. I was able to get it started after ten to twenty attempts, the car would run fine once cranked and would even restart immediately if warmed up. Now I'm getting nothing.

I suspect something electrical as an aside I noticed minor glitches when turning and using the signals

Almost sounds like it may have a vehicle recovery unit (GPS) installed. A lot of used car lots put these on their vehicles to shut down vehicles for non-payment, locating vehicles for non-payment, etc.. Some of the VRU's emit tones to indicate when you can start and cannot start the vehicle. I suggest listening to see if the sound(s) are coming form behind the dashboard. The VRU usually connects to a starter inhibit relay located somewhere fairly hidden. Find the relay and you can take it out, and all should be fine, of course you have to take the whole harness out and not just the relay. I found my VRU unit behind the fuse panel on the drivers side inside the dash and it was wired in to my OBD II with an adapter cable. Probably leftovers from a buy-here, pay-here car lot. Good luck and I hope this helps.

How can I bypass the security code


Why do think the key security is bad? If you still have a factory key, this is not the problem...if no factory key, you can take your VIN number or original key to GM dealer to get new key that they will program for you...Check for dirty battery connections:)

How can i stop my security light from coming on when i start my 2004 3.4 liter chevy impala ?


Hi Glenn, did you by chance replace your PCM with a used computer? If so you will need to have it reflashed, If not sounds to me like the Passkey security needs to be relearned. Also wondering why you replaced PCM after replacing EGR valve, Please if you can give me some more info on your veh. Body control module controls security so something is not right. Please get back to me, Thanks Randy.

2004 Chevy impala won't start sometimes


Is the "Security" light coming on?. If so, there is a problem with the Passlock key antitheft system. It is common for the ignition cylinder key detection contacts to go bad.

Replacing the key cylinder fixes the problem. The new cylinder has to be "relearned". See the internet and search for "2004 Chevrolet passlock system relearn procedure".

2001 Chevy Impala won't start


If the battery has gone dead, it could cause the security system to go into full lock-up mode. If it has locked up the accessories will work after the battery is charged back up , but the power to the starter will be cut off and it wont turn over. You need to do the 30 minute learn procedure. A GM dealer will print it out for you and you can do it yourself. It's very simple if you follow the procedure exact. hope this helps and good luck.
