My Civic keyfob is faulty. I've replaced the batteries, but it will only lock remotely, not unlock. The little lights on the fob flash when I press either button, but as I said, it won't unlock. Can anyone shed any light on this?
take it back apart and check the mechanical operation of the button. if you've ever taken something with buttons apart you might want to check that they perform the connection/switching part of the switch.
