2011 Buick lacrosse radio and temp controls locked
This often happens when the vehicle looses power. It is part of the anti theft system. There should be a code in the owners manual to unlock it when it prompts for the code. If there is not one in the manual or you don't have the manual, you will need to visit a dealer to get an override code. They should be able to give you a code for it in the future.

2011 Lacrosse makes a ticking sound under the hood
That noise is most likely the valve lifters, some noise is normal on these GM engines, if it is really noisy that is a problem. Do you use the correct grade of oil and change at least every 6,000 miles.

2011 buick lacrosse door lock does not work on drivers door only.
There could be many problems in this situation. Here is a list of some things to check:
1.) Check the wire connection in the door jamb where the wires transfer from the vehicle to the door. Sometimes these connections get a little off and things start acting goofy because the door being open and closed all the time(nothings perfectly designed).
2.) Check the relays in the fuse box, I can't remember if on this model vehicle if they used separate relays for each door or just one for all of them, but the relay could be bad.
3.) Check the locking mechanism inside the door by taking off the door panel and using a multi-meter and a 9 volt battery. I've checked the locking mechanism inside doors with a 9 volt battery before to make sure the mechanism was able to do it's job without being hooked up to the vehicle's power source

Is there a shut off sensor when the oil pressure drops and car shuts off?
Don't know about your car specifically, but most cars with electric fuel pumps are equipped with a oil pressure switch which cuts power to the fuel pump when oil pressure drops. The idea is that in a wreck when engine dies, pump should not run in case lines are cut which could dump fuel on ground and create fire hazard. Switch usually located with normal oil pressure sender.

2011 Buick Lacrosse how do you remove the cover on the positive post!!!
Hi Keven, I'm Al the owner of Big As Auto Repair
Keven, that flip down cover can be a bear to flip up some times especially if its been on there a long time. Take a screw driver and lay something across the battery to use as a ramp and take the screw driver and using the ramp pry upward on the very end of the cap and it should pop up. NOTE: Be careful though because some of those covers actually unlock from the other end. Hope this helps and if you need further assistance go to my website. Have an awesome day Keven!

How to put a freon into a 2011 Buick Lacrosse car?
there is an exact amount of gas to put in the system and if there is insufficient gas as you think then it would be advisable to have the system checked out for leaks otherwise you will not achieve anything.. Take it to an accredited auto air conditioner shop and save money.
