I purchased a 2001 V70 XC Country Wagon for my daughter that was in great shape with only 98K. Took a lot of elbow grease and time to make it look mint ( the OCD in me). The rear view mirror was half dimming. So I purchased a used OEM one off E-Bay. Now the key Fob will not work the door locks electronically. I tried the turn to position ll- 5 times on 5th time leave it wait for red dash light to flash. Never did. Did not work. Several attempts. Called Volvo, they said that I needed the car that the new(used) mirror came from to reprogram it. Which to me was saying they did not have a clue ! They are a large dealership that I have purchased 3 XC90's since 2005. (Long story,and not an inexpensive one to boot) My understanding is my next move would be to find a locksmith with the Volvo software that could reprogram it. Which I am finding out are few and far betwen,due to the expensive cost of the software. I am curious if anyone has any other potential solutions other than try another dealership ? Would appreciate it beyond belief. Thanks
