seconds and then turn off.
The new key is now programmed. The Remote Keyless Entry transmitter will

theres a long list of things that can make the engine stop running and not start back up... timing chain the coil or the electronic ignition computer fried fuel pump failed shoot some one could have put water in your tank, just to name a few.

This sounds like you have a ground problem with the fuel pump and sensor. This would
explain pretty much everything you are describing. Best to have a shop check it out
before you wind up stranded.

was the ignition switch getting hard to turn with the key for a while or did this just all of a sudden happen usually the problem has been going of for a while but people just ignore it until it gets to this point,it sounds like the tumblers in the ignition key switch have gone bad and the tumbler assembly needs to be replaced,the new tumbler assembly can keyed to the original key if the key is not worn out.this should be replaced with a new key if it is.

If you don't have the Panic button then sorry, you can't program yourself, the dealer will have to program it to the RKE (Remote Keyless Entry) module in the vehicle, using their DRB scan tool.

first try pulling on the steering wheel hard left or hard right while trying to turn the key.

Yes, the tumbler is worn, possibly from a heavy key chain or abnormally frequent stop/starts. Ther amy also be a bad connection in the switch connections itself, that may not require a whole new ignition switch.

try to get a jump from a friend and see what happens, does the same, faulty starter, may need replacing, try to use small hammer and tap lightly on the starter couple time and have a friend start the car while you tap lightly on it. check ignition switch where you stick the key in. stick the key in the ignition and turn the key back and forth jiggle and wiggle it and see if your igniting will make contact. do it several time to test and see if its the ignition problems, this part is not cheap to replace.

I had the same problem.does your key spring back? If it doesn't take out your tumbler remove your starter ignition switch,held on by one srew,remove top and bottom plasticcouple screws,two screws on top to remove blinker switchs and lights.under tumbler casing two small screws hold shift cble remove that and in between starter switch and tumbler the rest off your ignition. remove this at the more than likely at the end the soft metal has broken so instead off it having a square end it's rounded so it can't turn your ignition you will have to replsce that unit .goodluck It has been a real pain in the *** trying ti figure it out.
