It is very difficult to bypass because the anti theft system and immobilizer is there to stop exactly what you are trying to do. It is better to fix it rather than finding a way to defeat it.

Have the battery load tested at a local Autozone or other parts store, it sounds like it has a bad cell. The charging system is fine. Also make sure no lights are being left on like visor lights and glove box console lights.

Make sure the fuse is intact first. Purchase a Chilton manual or try a you tube video for help on getting to the module

Valet key is as good as regular key for the ignition

THERE IS ALMOST FOUR YEAR DIFFERENCE.CHECK WITH AUTO PART BODY REPAIR SHOP.THEY CAN TELL YOU WHAT YEAR GRILLE WILL FIT CAR.

What kind of problem are you having ? explain ! Can't open door power locks , inside an outside handles do nothing , can you unlock with key or key fob . Or is it a door latch problem ? If you can unlock the door but when you pull the handles ,an the door doesn't open , that's a latch problem . An that could be a tough one to fix. You would need to get the inside door panel off to get at the latch inside !

It likely means that you are low on oil and it is long overdue for an oil change. If you don't, you will be changing your engine.

near the fuel tank,follow the lines

Either your hinges need lube or the door is rubbing against a body part.

from the looks of this pull fuse 21 for dome and fuse 11 for the theft deterant then see if it still runs ok an has all the lights you need to git it to a clinic maybe. http://ww2.justanswer.com/uploads/ASEMaster35yrs/2011-09-27_081527_94-_95_buick_wiring.jpg

Look at the spark plugs for signs of oil fouling. If the plug has a white ash on it, then the engine is burning it.

they are located on the bottom of the ball joints, outer tie rod ends if they have been replaced other wise they are what is called permanently greased joints and don`t have fittings.

most likely a wheel bearing may be a brake caliper but your track code will indicate a bad bearing

Possibly your brake light switch may be improperly adjusted or may be shorted. Purchase a Haynes repair manual for your automobile and follow the remove, install and adjustment procedure in the manual. You should be able to purchase a new switch at your local automotive parts store. You should Google the brake light switch so you can get an idea of what it looks like. The switch should located either in front or behind the brake pedal lever. Before you purchase the repair manual and brake light switch, remove the wire connector off the brake light switch to confirm the switch or adjustment is your problem. I hope this helps and good luck! Dave

Usually it is under the car by the gas tank inlet and outlet hoses

probably a reprogram at gm dealer.

Cheap gas build -up in tank (Carbon build -up) lose Gas cap or combination of both

I was wondering if this was a trick question. If you don't see little screws holding the light cover on, you will have to access them from inside the trunk. remove/replace.

I had the same problem. Followed the repair steps documented on the website below. Works great now!
