⏳ Why Key Fob Batteries Fail Unexpectedly
Car key batteries don’t usually die instantly — but the signs are easy to miss.
🔋 Small coin batteries lose power gradually
📡 Signal strength weakens before stopping completely
🥶 Cold weather drains battery life faster
⏱️ Most batteries last 1–3 years depending on usage
Because the change is gradual, many drivers don’t notice until the key suddenly stops working.

Your key usually gives subtle hints before the battery fails completely.
