Here are some recommendations:

Use a Key Fob Cover: A silicone or rubber cover can provide a layer of protection against scratches, bumps, and drops. Imagine a tiny, durable suit of armor for your key fob.
Avoid Dropping the Key Fob: Try to avoid dropping your key fob on hard surfaces. If you tend to be clumsy, consider attaching a lanyard or wrist strap to prevent drops.
Keep it Separate from Sharp Objects: Avoid storing your key fob with sharp objects like keys, coins, or other items that could scratch or damage its surface.
Handle with Care: Treat your key fob with care. Avoid putting excessive pressure on the buttons or bending the key fob.
Consider a Key Fob Case: A hard-shell case can provide superior protection against impacts and crushing forces. It’s like a fortress for your key fob.
