The power door locks do not work either with door switches or the remote fab. Only way to lock or unlock doors is to manually lock or unlock doors, except drivers door which will lock and unlock with key. Remote start doesn't work because door can't be locked with fab. Took to dealer and was told that all 4 doors needed to have the actuators replaced. Priced over $1000.00. They offered to pay $350.00. It seems to me that there are problems with the control unit that sends signals to actuators, both by door switches and the fab. Based on the complaints filed I am not alone with, not only, this very expensive problem, but a severe safety issue.

We have a problem with our automatic power door locks and the remote start feature. They don't work, either by key fob or the power door lock buttons in the car. The only way we can lock our doors is manually. We took to the dealer believing it to be just the drivers door but they told us all our door lock actuators needed to be replaced, close to $1000.00 repair with no guarantee that the actuators are the true problem. After going on the federal safety agency site I see that we are not alone with these problem. I can understand a actuator going bad, but not all of them at one time. I am a former dealership gsm and very aware of "normal wear and tear" and "defects". I've never in my 35 years in the business seen this with door locks. I was insulted by their offer to repair them.
Tl* the contact owns 2008 buick lacrosse. The contact stated that all the doors had become inoperable and as a result, the door locks failed to unlock or lock. The contact mentioned that in one occasion the doors failed to unlock which prevented her from exiting the vehicle. The vehicle was not taken to the dealer. The manufacturer was not made aware of the failure. The failure mileage was 52,000. Updated 10/3/12 *cn the consumer stated the vehicle was taken to buick house. The consumer's son repaired the vehicle. The consumer could not afford the cost for the dealer to repair the locks. Updated 10/09/2012
Remote, remote starter (rke) fob for car stopped working properly. Replaced batteries even though dic did not show batteries needed changing. This maybe a problem also. Sometimes it works, sometimes it doesn't. Worked perfectly fine, then problems started. 99% of the time it will not start the car. 50% of the time it will or will not, lock or unlock car. I have tried resetting and/or personalizing keys & fob through dic center. Car will sound horn to show it has been reset properly, but isn't. Still does not work properly also when using rke, the door lock knob will not come up all the way and the door is not unlocked. Also, the door lick know will not go down all the way if I use the rke fob. If I use the key to unlock the door, the door knob will come up all the way and the door will unlock. If I use the rke fob to lock the door, the door knob will not go down all the way and the door will not be locked. I have tried using the fob away from all possible interference which I do not think is the problems, it still only works sometimes.
