Hi all, I'm having will some trouble with the remote fob on my Prado KZJ95 (1999). It's programmed and works to lock/ unlock the vehicle but works very intermittently. Even if I change the battery and it works well (but still not perfectly every time) it still very quickly becomes problematic and it also doesn't matter how close I get to the receiver. Sometimes I can be stood for a few minutes trying the fob before it works. Any ideas would be appreciated!
