1. Physical Damage: Cracked housings or broken internal circuitry from being dropped.

• Utilize a Protective Case: Silicone covers can protect the circuit board from the effect of accidental drops.
• Prevent Extreme Temperatures: Leaving a key fob on a control panel in the summer heat can harm the internal battery and plastic real estate.
