Key Fob Problem
I only got 1 fob with my car. It could be programmed but walk 20' away and it wont work when you walk back. It will work if re-synchronized. Then walk away and back and no work. I purchased 2 new ones from an online dealer. I programmed them as 1 & 2 and the old one as 3. The new ones work fine but same deal with the old one. I only need 2 but its driving me crazy so I thought if anyone has any ideas. The passive switch on the remote is off but that makes no difference. The passive feature works fine with the new fobs. Like I said I don't need to fix the old one mostly curious.

Sounds like you may have a cold solder joint on the IC inside the FOB since it works sometimes and does not others. There are a couple post here showing the repair. If you open the FOB and look at the circuit board it is in the upper right corner, think it is 4 or 6 pins. Might want to look at the battery leads also as they cause problems sometime.
Check this post...but there are better ones with pictures. just need to search

I looked at the thread and then at my fob. I do belive that those connections could be the problem. I will try to fix it this weekend. I don't need it so much now but I hate to throw stuff away. A spare can't hurt anything.
