Tools Needed:

Step 4: Insert the New Battery

- Insert the mechanical key back into the slot.
- Test the key fob by pressing the lock, unlock, and remote start buttons to ensure everything works.
How Often Should You Replace Your Kia Key Fob Battery?
On average, a Kia key fob battery lasts 2 to 3 years before needing replacement. However, this lifespan depends on:
- Frequency of use – More frequent use drains the battery faster.
- Climate conditions – Cold weather can reduce battery life.
- Battery quality – Cheaper batteries may die sooner.
If your key fob is not responding well, replace the battery immediately to avoid being locked out of your vehicle.
