1999 Pontiac Sunfire Ignition problems

I have a 99 Pontiac Sunfire, and when I go to shut the car off, it's like the key doesn't register that I am shutting it off, so I have to push the key back up one notch to get the car shut off. Would this be the ignition switch or something else? Someone told me that if I replace the ignition swith that I will have to take it to a dealership to get it 'reprogrammed'. Can anyone please help me out?

Hello Brittneyc_07,

"Someone" is LARGELY correct...

If you change out the entire security lock...
Keys, cuts, codes & all (then your doors won't
match either...
so you really ought CHANGE EVERYTHING...

But WHY? (if only your switch is defective??).

But if you have a locksmith merely change the SWITCH...
(use your old keys... & code the new Ignition switch correctly)

"SOMEONE" is full of more "stuff" than a Christmas turkey.

Locksmith can come to you...

Charge less than dealers...

Perform only necessary work...

but the fact is... You could VERY LIKELY do
all the work yourself:

Check out the prices below...
Call your local locksmith & GET AN ESTIMATE...

GM has a process for OWNERS to "reprogram"
their own keys... It just takes a really long time...

My guess is the lock cylinder can be re-keyed
to the original keys... and will work fine...

Check with your local LOCKSMITH after compaying the prices below...

Hope this helps...

Try squirting some lubricant down the barrel of the switch.

SOURCE: How do you replace brakes on 1999 Pontiac Sunfire?

The engine size don't matter except when you order the parts. First you will want to chock the rear tires. This is a front wheel drive, when you jack the front, park wont work. you should also set the parking brake.
You will want a metric socket set and rachet, and a fairly large flat head screw driver.
Remove the wheel.
When you look at the brakes, you should see 2 bolts holding them on, If they have a star shape that looks like a screw driver might fit in it, it is a torx bit, you will need to replace the wheel and go get one. The guy at the parts store should be able to tell you what size.
I'm pretty sure it is going to be a regular hex nut, probably 12 or 13mm.
You can loosen them, but don't remove them yet.

First you need to depress your caliper. This can be done a couple ways.
I just insert a screw driver between the pad and the rotor(the shiny thing that the pads make contact with.) Carefully pry the inner pad slowly away from the rotor. Don't scratch the rotor, you can dig into the pad all you want, your putting new ones on.
Once the inner pad is all the way in, then you can remove the bolts and the caliper will slide out.
Remove the old pads and replace with the new.
Put the caliper back on, make sure you get the bolts tight.
Do the other wheel the same way.
The other way to get the caliper pushed in, by the way.
Remove the bolts, remove the caliper from the rotor, Use a large "c" clamp to depress the cylinder.

P.S. Do not under any circumstances remove your brake lines.

When you are finished with brakes and have tires replaced....

Caution!!! Before you start your car, pump your brakes a few times. Check your brake fluid. You more than likely wont need any, but you should always check it.
Also, do not add brake fluid before replacing pads, the level is going to be higher with new pads.

Back brakes will be similar if it is disc, if it is drum, do your self a favor and have some one else do it or get a service manual. I could walk you thru it, but you need more tools and you have to adjust them....
Better to pay $100 or so and have it done right.

Car starts run's 3 seconds shuts down

Your car is equipped with a system called PASSKEY standard on all GM cars and light trucks, try the following procedure to reset the system, the battery being dead will trigger the system.

1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the passlock system to recognize your key.
