Relearn procedure--- Turn the key on for ten minutes, turn it off for five seconds. do this three times and after the third time it should start. Just a note... Put a battery charger on it as this procedure will drain the battery.

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:)

2000 chevy impala starts rough, replaced pass lock cylinder, mass air flow sensor, still starts and dies, usually by the third time of this it starts normal and runs like no problems


When was last tune up? Plugs, wires, all filters & fluids??? Especially fuel filter??? I'd start there and run a good fuel system cleaner through it with next tankful of fuel. You might also consider having a fault scan done. (OBII scan) Autozone, Advance and any good parts store can do it for you FREE

2001 Chevy impala had ignition switch replaced, once i turn the key, "security" flashes on screen and car won't start. How do I fix this so that the car will start?


Turn the key to "on" and let the light flash. It should stop flashing after about ten to twenty minutes. Once the light is on steady, turn it off, then start the car. I usually put another battery on jumper cables attached to the cars battery so it does not run down and die before the system re-arms.

How do i reset the security system on my 2003 chevy impala


Are you reffering to the alarm or the pass lock system that put the theft light on.....If its the alarm the put the key in the door and unlock it. If its the pass lock system put the key in the ignition and turn it on and try to start the vehicle. After it shuts itself off leave the key on for ten min until the theft light stops flashing the turn key off and try to start it again. This may take a few times....

1994 chevy impala will not start battery is charged


if the pass key light is flashing you may have to take it to a shop and have it diagnosed. i had this problem with my 98 sonoma. my problem was that the pass key sensor was bad. for some reason the car is not recognising your ignition key and is going into security mode. this one is almost impossible for the do it yourselfer unless you have a scan tool. (not a code scanner) this is how gm gets you.
