KeyFob stopped working.....help?

[jasonator]

I bought a used 2004 4runner SR5 about a year ago and everything has worked flawlessly since. My KeyFob (OEM) just suddenly quit working. I have put a new battery, and also tried to reprogram.....neither of which has worked. Can anyone point me in the right direction? I have searched, but not much comes up regarding this issue. Thanks in advance.

how often do you drop your keys?

my remote start fob did the same thing. i tried a new battery, still nothing.

i pulled it apart, one of the solder joints to the battery came loose. i resoldered it, and its been working fine ever since.

its worth a shot to check.
