2006 Buick Lucerne Q&A
2006 Buick Lucerne Question: Remote door locks quit working.
Dealer checked key fobs and they were working. Dealer Tried reprogramming, didn't work. Put computer on, told me to come back and put it in shop, something about module? Any cost ideas or suggestions? - Visitor
I had this same issue & it was only due to a awire that came aloose in the trunk while putting stuff in & out.... Located in between the speakers in the trunk. I went thru the same exact situation... The dealers techs sucks ass! I ended up finding the problem my self... Plugged in the loose plug & wah-la remote locks again... Im pretty sure with this problem your tire pressure monitor was off as well.... - rrjam
