Trunk button Not Working on Buick car ?

Its a recall.First inspect its not got pushed in and stuck up or itys not got cracked or broken.
By " Trunk Button"? Are you referring to your key-less remote? Or the yellow button in the glove box? First check to make sure that you have not accidentally set the valet switch to LOCK. That will disable the remote & the yellow button from working. Info on how to do that is in your owners manual.
FYI, there was a technical service bulletin on your key-less remote. Buick redesigned it [they had problems with the trunk opening accidentally] If you need a new key-less remote, the new part number is P/N 25678792.
If the solenoid for the power trunk lock has failed, the remote will not work. Assuming you can not open the trunk using the trunk key, there is one last method to get into the trunk. You must remove the rear seat assembly. Then remove any plastic or paper covering which may separate the trunk from the rear seating area. Using a good flashlight, a 3/8" drive ratchet, several extensions [totaling 3 feet in length} and the proper flex socket [most likely 8mm, 10mm or 13mm] you can remove the three bolts which hold the latch mechanism from the inside of the trunk lid. The trunk lid will then open. At this point, you can get your stuff and fix the problem with the power trunk mechanism.

This basic details will help.Thanks.
