Battery Replacement
This is the most frequent repair. Most fobs utilize button-cell lithium batteries (such as CR2032 or CR1632).

Button and Shell Refurbishment
In time, the rubber buttons on a fob can tear, or the plastic loops that connect to a keyring can break.

If a particular button (like the "trunk release") stops clicking, the internal micro-switch might have removed from the circuit board.
