My key fob won't work on my volvo s70. It all started a few days ago when it got a bad connection, sometimes it worked and some not. And now it have gave up on me it doesn't work at all. I Have changed battery so that's not the problem and the key works. I am wondering if you guys maybe know what it can be, maybe it's something in the car that's crazy? Please help.

 

What year is the car -

 

Year 2000
