Physical Casing Damage
The plastic real estate (or shell) of a key fob is typically the first thing to stop working. With time, rubber buttons can use through, or the plastic hinges on "flip" keys can snap. This exposes the delicate internal circuit board to wetness and particles.
Micro-Switch Failure

Transponder Issues
If an automobile cranks but refuses to begin, or if a "Key Not Recognized" light appears on the control panel, the transponder chip may be harmed or out of sync. This requires specialized diagnostic devices to remedy.
Battery and Power Connection Faults
While numerous owners can change a basic battery, some secrets (like those from BMW or Land Rover) use rechargeable batteries soldered directly to the board. In addition, the battery contacts can end up being corroded or loose, requiring professional re-soldering.
