3. Misaligned or Broken Buttons
The rubberized buttons on the outside of the fob press down on "tactile switches" installed on the circuit board. With time, these switches can end up being desoldered, or the conductive pads on the underside of the rubber buttons can wear away.
4. Circuit Board Corrosion
If a key fob is immersed in water or exposed to high humidity, the internal copper traces can wear away. This disrupts the circulation of electrical power and causes periodic or total failure.

The Foil Fix: A short-term DIY fix includes gluing a tiny piece of aluminum foil to the bottom of the rubber button to restore conductivity.The Shell Replacement: A more irreversible service is buying an "empty" fob shell online. You simply move your existing circuit board into the brand-new plastic housing.Cleaning Internal Corrosion
If the fob has actually been exposed to liquid:
Disassemble the fob totally.Get rid of the battery.Use 90% isopropyl alcohol and a soft-bristled toothbrush to carefully scrub the green circuit board.Let it air dry completely for at least 24 hours before reassembling.Specialist Repair vs. Replacement
