How do you replace the remote key or the smart key?

The battery in your Kia's intelligent key will eventually need to be replaced, whether it's a remote that starts with a push button or a normal metal key that doesn't contain transponder. This is particularly when your car displays a message indicating that the remote or smart keys are in poor condition.

This is a relatively simple process. To replace the battery on the keyfob, remove your mechanical key from the slit on the back of the fob. Then, pry the cover open. A small screw is inside the key fob, which holds the battery in its place. Remove the old battery by unscrewing the screw using the help of a small screwdriver. Then, insert the new one and close the slit inside the key fob.

Test the key fob by pressing the lock or unlock buttons. It's good in case the doors lock and unlock as you expect. You can now make use of the hands-free lock/unlock feature on your Kia whenever your fingers feel cold or you have to go on errands around Brandon.

Note: Some key fobs (transponder chip or smart keys) may need to have their programming completed. This requires a particular programming machine that only the dealer or automotive locksmith has access to. Other keys (non-transponder metal keys) don't require programming. If your key has to be programmed, you will need to know the key code number printed on the tag of the key code and record it in a safe location.

How do I replace the battery?

How do I replace a smart key

Depending on the model of the Kia Sportage, you may have an ordinary key fob or a smart key. The difference between the two is that the smart key comes with a small mechanical key blade tucked inside it, while the standard fob isn't equipped with. Both types of key fobs have batteries inside that eventually will need to be replaced. It's an easy task that takes just two minutes.

How to replace the mechanical key

The Kia key fob is a great convenience that lets us lock and unlock our car at the touch of the button. But, as with all devices it may have issues occasionally. There are steps to take to fix these issues and ensure that our key fobs are in good working order for the long run.

One of the most frequent issues is a low or dead battery. This can cause your device to stop working or work intermittently. If this is the issue, replace the battery with an entirely new battery.

If this does not resolve the issue, try using the flathead screwdriver that is standard to push the plastic casing of the fob open. Be careful not to scratch any internal components or scratch the plastic. Once the battery is opened, carefully remove the old battery and replace it with a new one.

When the new battery is in, close and open the doors with the mechanical key (every Kia fob has an emergency mechanical key that will fit in the slot). Test the fob to make sure it's working properly. Contact a dealer, or a locksmith to address the issue when the fob still is not working. Make sure they cut you an emergency key that functions in all the door and trunk cylinders to prevent lockouts in the future.
