Now there is a way to Bi pass the system. yes I said bi pass. the pass lock system GM uses is junk. they should have fixed the issue with a recall years ago. there are a few ways to also check if it is the system itself though. the first part is a relearn of the key.

turn the key like you are going to start the car ( but do not start it) let the key sit there for 10 min ( repeat this step total of 3 times) o the 3rd time after the 10 min is up try to start the car. If it starts you should be good to go. If it don't start you can go ahead and go to local junk yard. get a cross reference from the people behind the counter of what you need. it will be the ignition lock cylinder that you need. ( yes the entire lock cylinder ) also if you are savvy enough get the trunk and the door locks too. ( that way you don't have a bunch of keys on your key chain just 1 key. ) but you replace the lock cylinder ( since the cylinder itself has the chip for the security system in it) then you do the relearn all over again. this should solve the problem with the car. I have done this a few times on GM vehicles because the pass lock system is junk. to bypass the system just ask and I will send you a link for the instructions on how to do it.

SOURCE: 2005 chevrolet impala won't start, security light flashes

The security icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

Changed water pump, car wont start


Starts everytime and shuts right down? Usually an indication of the security system. I had to bypass a 98 Malibu because of this. A lot of those era Chevys had problems. Check the videos on it. I don't know exactly what one your car has. 2005 impala security bypass YouTube

Security light on 2005 chevrolet impala won't crank


More then likely it's your key.
The security key setup has resisters that slowly lose the resistance required to start the car.
You can call the dealership and give them the VIN they should be able to assist you.
If not then you will have to get a new ignition

Security light stays on, 2005 Impala, car starts every time


Did you check for error codes (DTCs) using a scanner that will check the BCM codes? A GM dealer's scan tool would probably find the problem right away. The security light driver in the BCM could be faulty, although that probably won't throw a code.

My 2005 chevy impala won't start since someone broke into my car


i would say when the person broke into your car they set off the security system which stops the car from starting, the way to reset the security is to put your key into the ignition turn the key until all the dash lights come on and let them stay on about 15 minutes after the 15 minutes have expired turn the key off and wait about 3 seconds and then your car should start. hope this helps.
