1999 S80 - Replaced Battery In Key Fob Remote Now It Doesn't Work
 

Over the last few weeks I've had to get progressively closer and closer to my car to have the keyfob work to lock and unlock the doors. It got to the point where I had to hold the remote to the window, it wouldn't even work a few inches away from the car.

So I put a new CR2032 battery in it and it still does not work. Using a multimeter I found that the new battery is in fact putting out just over 3 volts and the old one well under 1 volt.

So what do I do at this point? The owner's manual does not cover this situation.
