Gradually, flexing the card in pockets, dropping it on tough surfaces, or natural battery destruction causes internal solder joints to break and batteries to stop working.
Common Symptoms of a Failing Laguna Key Fob
Recognizing the particular symptom can point straight to the appropriate repair. Here is a breakdown of typical problems and their likely causes:

Place it under a magnifying glass. Look closely at the soldered connections-- specifically around the big copper coil antenna and the microchips. Look for dull gray rings, fractures, or loose components.Reflow the Solder: Plug in your soldering iron. Apply a small amount of fresh flux to the suspect joints. Touch the hot soldering iron tip to the joint till the solder melts, reconnecting the part securely to the board.
