I have a 2001 Volvo V70 and for the past couple of days my key fob has been extremely picky. I am having to press the buttons very hard for them to work, and usually even when they do they only open the trunk and doors on the left side of the car. I have gotten it to work on the right side a few times, but only while pressing very hard in the bottom corner of the unlock button.
Before a couple days ago it was working perfectly. I have tried replacing the battery and swabbing the circuit board with a bit of alcohol, but no luck. What could be wrong and how can it be fixed?
On some cars, if you press the unlock button just once, it only unlocks the driver’s door and nothing else, but if you press the unlock button twice (or hold it down longer) it unlocks everything. Maybe what’s happening is that you previously were holding the button down long enough to unlock everything but now the buttons are wearing out and where it used to interpret what you’re doing as “continuous contact”, now it sees your action as “intermittent contact”.
Try getting a brand new remote and see if the car does the same thing with that one. If it does, then you’ll know it’s not the remote, it’s the car.
