Question about 2000 Buick Century

2 Answers

2000 Buick Century wont start, new ignition switch with new keys and both used to work (replaced several months ago). Neither key will start the car. Seems like the security system. Been sitting for 2 days now and still wont start. I hear the fuel pump start, head and dash lights come on, window work. No engine action. Ideas?

Had similar problem on my Mother's '01 Impala. Try cycling the remote keyfob between "lock and Unlock" several times and see if this lets it start.

From what I've gathered, this has been a significant source of irritation to GM owners from about '00 thru '03 model years.

Good Luck!!!

    Does the security light come on? Do you have a chip your key? You have a problem with your VATs security system. If your car stops running while driving or wont start, you're gunna be spendin some money to have this system fixed. Do it for cheaper. this guy has the answer.....http://newrockies.ca/?ap_id=judd0081 Trust me, i just did it on my buick regal. took about 2 hours, saved over 500 bucks. This not starting issue has been a problem for a year for me. Temperary fix, turn your key forward 2 clicks till right before it would normally start, wait ten minutes. turn it back then forward again to start.

Make sure all the fuses are good. Check the fuse panel inside the car and the fuse box under the hood. Find the starter relay and swap it with another one and see if the starter works. If that didn't make any difference, try this:Make sure the transmission is in park, emergency brake on. Turn the ignition key on. Find where the positive battery cable is attached to the starter. Attach one end of a jumper cable to the connection. Take the other end of the jumper cable and ground it against the starter solenoid where the wires are connected. This should start the car, or at least make the starter work.If the car starts but won't stay running, then it is probably the security system at fault. If you went to a dealership for the new switch and keys, you probably paid quite a bit for it.There is a cheaper way to fix it, and it will last forever. It's a bypass system from a company called New Rockies. I think you should check out this website: http://newrockies.ca/vatsbypass.

2000 buick century ignition stuck on


Hi David I'm glad to help!

David I've found from time to time an Ignition switch will stick because the tumblers freeze. If you in fact have a tumbler and key set-up here a way that usually works but not always. Remove the key an spray lubricant into the key hole, then replace the key and using a small hammer tap on the end of the key while turning it off. Once you get it to move you'll need to replace the tumbler and housing assembly. NOTE: If you have a WIN Module set-up then remove the negative battery cable for 20 seconds then reconnect it and see if it works properly. This is only if you have the Module and key set-up, this has nothing to do with the key and tumbler. Hope this helps and have an awesome day David.

I can not find the neutral safety switch on a 2000 buick park ave


Any chance your vehicles have a security/alarm system. Disconnecting battery on some, will arm it sometimes & not allow it to run. Using key to unlock door, on driver & passenger side have been known to work on some vehicles, but if not, a call to dealer should help.

02 Park Ave, Need to know how to program new key to ignition.


Take the original key, if you have it. Start the car, kill the car then start it with the new key. This will work for adding a key. If you are replacing a lost key then you will have to learn it to the theft system.Place the key in the ignition, turn it to run for 10 min. Cycle it off then back to run for 10 min. Cycle it off then back to run for 10 moer minutes. When the 30 minutes is up turn it off then try to start it. Thai should work. I have had to do it more than once. Good Luck

Check the cylinder, maybe the magnetic spot is not contacting the correct area of the cylinder. Cylinder may be loose, also poosibly bad computer chips on the keys.
