How to Replace a Kia Sportage Replacement Key
For many Kia models, the key contains the keyless entry system that is built into the key. This key typically resembles a remote control and is able to be replaced with a fresh one from an Kia dealer or a locksmith.
Key fobs might stop working for a variety of reasons, such as a dead coin battery, worn buttons signal interference, water damage, and a defective receiver module. Here are some suggestions on how you can get your Kia Sportage replacement key to function again.
How to replace the remote key or smart key
The battery inside your Kia's smart key will eventually have to be replaced, regardless of whether it's a remote or a push-to-start one, or a normal metal key that doesn't have transponder. This is particularly relevant if your vehicle displays a message telling you that the smart or remote keys are in poor condition.
It's a fairly simple process. To replace the battery in the key fob, remove the mechanical key from the slit in the back of the key fob. You then need to remove the cover. Inside the key fob there will be tiny screws that hold the battery in its place. Remove the old battery by removing the screw with a small screwdriver. Then, you can insert the new battery and close the slit inside the key fob.
When the key fob is equipped with an updated battery and you've tested it, press the lock and unlock buttons. If the doors unlock and lock in the same way, you're good to go! You can now take advantage of your Kia's hands-free lock/unlock feature when your fingers start to get cold or you have to run some errands in Brandon.
Note: Certain key fobs might need to be programmed (transponder chips or smart keys). This requires a particular programming machine that only the dealer or locksmith can access. Other keys (non transponder keys made of metal) do not require programming. If you want to change the programming of your key, you'll need note the key code number on the tag for the key code.
How to replace the battery
If the Kia key fob is unable to respond to pressing the lock/unlock button, it's likely that the battery is insufficient. A low battery could cause other problems like the check engine light coming on or delayed engine cranking. It is fairly easy to replace key fob batteries by using only a few simple tools.
Make sure that you shut off your vehicle and close all doors prior to beginning. Locate the small metal or plastic piece that is on the bottom of your key fob and gently jiggle it until the metal key slips out. You can then put the key into the handle of the door for the driver to open your car.
To replace the key fob battery, remove the cover on the rear and use a plastic bar tool to remove the latch holding the black negative battery cable. Remove the old battery and orient the new battery in a way that the "+" positive side faces you and the "negative" negative side is facing the fob's electrical contacts made of metal. Avoid using excessive force when pushing the new CR2032 into position to avoid damaging or breaking the metal contacts.
After installing the new battery, turn the key fob off and on in the ignition until the door locks up. You can then test your Kia key fob to determine whether it's functioning properly again.
How do you replace the smart key?
Depending on the model of the Kia Sportage, you may have an ordinary key fob or a smart key. The smart key features an embedded mechanical key blade, unlike the standard key fob, which does not. Both kinds of key fobs come with an internal battery that eventually will need to be replaced. It is a simple process that takes only two minutes.
Be sure to switch off your Kia, and be on a flat or well-lit surface prior to when you begin. Be aware that there are tiny parts inside the fob that can be removed if not cautious.
The first step is to locate the small release button that is located on the lower backside of the fob. It's either an oval or circular slot. After pressing The Key Lab , the mechanical blade will come out and you can then open the key fob.
After the key fob has been opened, take out the battery that was in it. The new battery is a C2032, and can be purchased online or in your local auto parts store. Once you're done, your key fob should permit you to lock the vehicle, unlock it, and then start your vehicle, even if it isn't running.
