Does it keep cranking like when first starting or is it running normally and when you turn off the key it just keeps running if it's the first one the solenoid on the fender is N/G the engines running but the starter is still cranking trying to turn the engine over but it's already running///// next if it's running normally after starting no grinding from the starter being engaged like I just described then the ignition switch on the steering column is N/G//// THIS IS NOT THE IGNITION KEY SWITCH THAT YOU PUT THE KEY IN TO START THE TRUCK THIS IS LOCATED DOWN ABOUT HALFWAY BETWEEN THE STEERING WHEEL AND YOUR FEET THERE IS A ROD THAT COMES FROM THE KEY SWITCH WITH THE KEY THAT WHEN YOU TURN THE KEY YOU ARE MOVING THIS ROD WHICH MAKES THE SWITCH MOVE TO THE POSITION TO START THE TRUCK WHEN YOU LET GO THE SPRING INSIDE LET'S THE SWITCH MOVE TO THE RUN POSITION SO WHAT'S WRONG HERE IS THE SWITCH IS NOT OPENING WHEN YOU TURN THE KEY TO THE OFF POSITION IF IT'S A NEW SWITCH YOU HAVE TO ADJUST IT TO GET IT TO SHUT OFF THE RIGHT WAY IF IT'S AN OLD ONE REPLACE IT BUT THIS COULD HAVE BEEN REPLACED BEFORE AND THE FASTENERS LOSSENED AND MIGHT NEED TO BE ADJUSTED AGAIN AND TIGHTENED TO HOLD IT IN PLACE GOOD LUCK!

some cars and trucks have a keylock on the steering collum under the wheel somewhare there is a little knob, lever, or button. on the collum or right by the key. that when pushed, pulled. or turned releases the key to the full off position. just give it a good look over im sure youll find it. you have to be moveing the key back at the same time while useing the lever. im assuming you have just bought this car and wasent shown how to unlock it.. however if you have had this car awhile and this has never happened before you need a new ignition switch on the collum. i hope this information helps..
The reset is'nt possible it's problem to get get. Your key has a (chip) it it it's realy a diode that has a certain resistance. The key lock has contacts in it that touch this diode and relay this resistance to the computer and then it's happly and let's the car start. Most of the time the contes are Okay but you should check before you go into the next thing to check. looking into the lock where the key enters and start to insert the key and you can see the contacs tring to touch the key. if their bent or way off the key with a small bent pick you can bend the contacs so they'll pust on the key more, don't get carried away as too much and the tip of the key will bend it all the way out of the way. If this does'nt seem to be a problem the next step is to verify that the key is being read and you first need to read the key it's self with an OHM meter. It'll be 100 OHMs or 200 and so on. then find the same wires art the floor board as the wiring comes out of the steering collum. There's a big electrical connector near the base of the steering collum with a bolt in the middle holding it plugged in. On the outsides of this plug are a piggybacked plug on both sides of the main plug in on of these piggyback plugs coning from the steering collum are going to be two white wires all the way to one end of the piggy back pulg and their very thin and right next to each other, these are the wires that should be the key if it's connected. with this plug unplugged and the key all the way into the lock these two wires shoul read the same as the reading you got when you read the key itself earlier. if it does read the same your in troble bad as the computer has locked you out and a GM dealer will have to connect you to thier interface to unlock your car. This is not likly to be the case as the wire that we're testing is more likly to be broken the right way and an altentive( cheaper) way is possible you can go to the store and but a lock and key cyclinder for your car
This wire connector on the lock cyclinder you can put your key in this lock you just bought and connect the wires where the white ones in the plug were and use a spare key to turn your old lock and the security will read your key as it's connected now and you can turn the lock in the collum and it'll start and run. or you can fix it right. If you have the tools and skills. ( you can rent some of the uncomon tools at the parts store that your buying the new lock cyclinder. You need a steering wheel puller and a lock plate depresser. you also need the tools like picks and skill to use the lock plate depressr. Once the lock plate is out then you can remove the torx headed bolt ytheat holds the lock cyclinder in and remove it. I connecte a wire ( coathanger to the old wire before I pull it out of the collum so the new wire can but pulled back in to the same place were the old wire was ( it needs to be). If the old lock was working smoothly I just remove the contac ring from both the new lock and the old one and put the contacs and the wire on the old lock then re assemble it and it will work with your old key and will have the new wire. be careful to rount the new wire the same as the old on with just enough slack as you turn the key as it'll break the new one if it's too tight or if theirs too much slack in the wire it'll hang in the lock plate and get cut by it. I f you need to use the new lock and key you'll need to get the new key copied and a key cutter with the same diode resistance and alot of key cutters don't do this work or charge alot of money to do it . The dealers charge about $500 to do this work. Repairing the wire does'nt last very long as it brole as it flexes as you turn the key right where it breaks and the repair will break even eaisier.
Your ignition switch is located on the left side of the steering column itself, right below the dash. You won't see it until you remove the lower part of the dash panel. But, I think your starter relay might be the problem with your no start condition. Try swapping the windshield wiper and starter relays to see if that helps it start. If not, then maybe it is a bad ignition switch.
The ignition key cylinder in a Buick
unlocks the ignition and allows the Buick's engine to start. The
cylinder contains a switch on the end of it (inside the cylinder) that
sends an electric signal to the starter motor. When the ignition key
cylinder fails, the Buick won't start. When this happens, you'll need a
new ignition cylinder. Purchase replacement cylinders from Buick. Difficulty: Moderately Easy
Things You'll Need:
Remove the screws on the bottom of the steering column on
your Buick. These screws hold the steering column cover on. You may need
to tilt the steering wheel to its highest position to access these
Turn the ignition key to the "II" position in the ignition cylinder.
Slide the punch pin into the access slot on the bottom of the ignition cylinder.
Push the pin all the way into the access slot while you pull the ignition cylinder out of the steering column.
Insert the new ignition cylinder into the steering column with the key in the "II" position on the cylinder.
Push the cylinder into the column until it "clicks," indicating that it is locked into the column.
you will have to take the steering wheel off and the steering collum apart to find the rod that actuates the real ignition switch..the thing you stick your key in..is not really the ignition switch....its just a key tumbler..and it would be best that a professional replace the key tumbler..because it is difficult to drill out..i know this isnt what you wanted to hear..but i hope it helps
