I think this is that silly security system a lot of cars have now. You have to open the driver's door with the key, or else it goes bananas.
I would lock all the doors, remove the battery terminal, wait at least 5 minutes, and then try unlocking the driver's door again.
(of course if there is something wrong with the driver's door lock, then fix that first.)
If the alarm system is still not working right, I would just hot wire a momentary push button to the starter solenoid and leave it at that.

I hate it when they put complex electrical devices like a security system in a car that sits outside in the cold, heat, rain, etc.
They make cars worse and worse all the time.

2007 pontiac G5 door assembly


The lock may be stuck in locked position in the latch assembly.
Roll the window down,reach inside the door and move the lock button to unlock JUST as you give the door a severe whack with a rubber hammer at the outside door edge 1/2 way down the door at the door latch area.
It may take more than one try to unlock the door,if that's what is wrong,but usually is.

Security system went off after replacing battery now car wont start nor fuel pump will turn on.how do i fix


You might just need to reset it. Roll the drivers window down and close all the doors. Lock all the doors with the key ) turn the key to lock twice, The electric locks should lock all the doors. wail a few minutes and unlock and open the trunk with the key. relock the truck or just close it. unlock the drivers door with the key, twice. all the doors should unlock, get in and start the car. Now this does'nt always work. If it does'nt we'll make the system think it's running. Close and lock all the doors. open the hood and disconnect the battery, one ccable will be fine. wait a few minutes. Reach in though the open window and turn the key all the way on. Don't open the doors, go around and connect the battery hard so it does'nt jump or skip. Reach thought the window and start the car/ once it's running. turn it off remove the key and unlock the door from the inside and open the door ( as if you were inside.) get in and start the car and everything should be back to normal.

It's probably an anti theft lockout device that disables the ignition and /or starter. I would say there's no way to reset it without going through a dealer. If you have a key fob that unlocks the doors electronically you might try using that. Or try locking the open door then closing it and unlocking it again then getting in and trying to start it. Try all kinds of combos but I'll tell you...replacing batteries, fuel pumps, things like that will just be a waste of money. Try all those little combinations of locking and unlocking the car, if none work...call an Infiniti dealer. I know it stinks but with a car stolen every few seconds it's really for your protection. Good luck.

My steering column is locked and I cannot get the key to turn to start the car. I have a 2008 pontiac g5.


The battery dead? Remove the battery cables and wait and then see if the key will turn. If it will not remove the key ( will it come out?) the key can be the wrong one ( maybe) you can have a blown fuse. Any fuse so you need to check them all. If the key will turn with the battery disconnected then put the car in park and turn the key off and remove it from the car. with the window down and the doors all closed and the hod open reconnect the known good ( charged Battery) with the battery connected don't open the door but reach in and put the key in and start the car. the doors should lock when the engine starts. reach in and unlock the door and get in and close the door. then turn the car off and remove the key get out and close the door and lock it with the key. wait a minute and then unlock the door with the key get in and drive away like normal. do everything though or you'll unset the reset cycle. Make shure that the break lights work as they control the unlocking feature of the collum.
