Can Onstar unlock my car?
Yes. It could not on older 9-3s, or any 9-5s. There was some confusion as far as what salespeople said vs. Onstar’s website vs. what’s in the Owner’s Manual. But I’m happy to report that I actually tried it during my trial period with Onstar. I called 1-888-4-onstar (1-888-466-7827) and asked to unlock my vehicle. They asked for account number & PIN & they said “Wait 10 min & if it is unsuccessful we’ll call you back”. Their first attempt was unsuccessful, but their second attempt was! Yippie! (First time failed due to weak Onstar cellular signal). It unlocked all doors, BTW, not just Driver. In the Infotainment Manual that came with your car, on page 92 under “Remote Services” you can “lock any door of the car or unlock the driver’s door”. Source Back to Top My Speed Dependant Volume (SDV) doesn’t work! There is a setting in your radio called Speed Dependant Volume. It’s goal is to automatically make the radio (or anything coming through the head unit) more audible at higher speeds. S
