I have a 2004 Impala with 140,000 miles on it. I've owned it since brand new. I noticed the last few weeks, I need to stand right next to my car to lock or unlock the doors with the keyfob. When I first started noticing it, I though obviously it's the battery. The battery in the keyfob is now 8 years old or so. I bought a brand new battery and replaced it, but the problem didn't go away.

So, now I'm wondering is the keyfob itself bad? Or is it common for this problem to be caused by something else?

You know, I just got to thinking, recently I bought a new FM modulator for my iphone and it's interfered with my GPS (built in the iphone) and cellular in the iphone. After monkeying around with the fm modulator for a day or so trying different frequencies, I found one that didn't interfere with all that stuff. I wonder if that being on all the time is somehow near the frequency of the door locks... I just thought of that at this moment. I'll have to check that.

But does anyone else have any other ideas?
