What is a Key Fob?
A key fob is a small, hand-held remote control that is used to unlock and lock the doors of a car from a distance. Key fobs are also used to activate the panic alarm for the car’s alarm system, and some even open the vehicle’s back hatch or start the engine before you even get in. Most key fobs have small buttons that activate each of these actions when they are pressed.
What Causes Key Fob Issues?
If your Kia key fob is having issues, it can be confusing as to why. There are actually several different factors that can cause key fob issues. Let’s look at a few of them below:
1. Weak Battery
One of the most common problems is a weak battery. If your key fob’s battery is getting low, it may not have enough power to properly operate the remote. This can cause the key fob to work intermittently or not at all.
If you think that your key fob’s battery may be weak, try replacing it with a new one. If your Kia key fob battery replacement doesn’t work, then you will need to try something else listed below.
2. Worn Buttons
Another common issue is dirty or worn buttons. Over time, the buttons on the key fob can become worn down or packed around with dirt and grime. This can prevent the button from making a good connection when it is pressed.
If your key fob buttons are dirty or worn, try cleaning them with a soft cloth. You can also use a cotton swab dipped in rubbing alcohol to clean the buttons and a toothpick to clean around them in the crevices.
3. Dirty Circuit Board
The circuit board is the part of the key fob that sends signals to the car. If this board becomes dirty or corroded, it can cause problems with the key fob.
To clean the circuit board, you will need to remove it from the smart key fob. Once it is removed, use a cotton swab or rag dipped in rubbing alcohol to clean it. Allow the board to dry completely before replacing it in the key fob.
4. Faulty Connection
Another issue that can cause key fob problems is a faulty connection. If the connection between the key fob and the car’s receiver is poor, it can cause the key fob to work intermittently or not at all.
If you think that there may be a problem with the connection, try standing closer to the car when you use the key fob.
5. Fob Needs to be Reset
Sometimes after a battery replacement, the Kia smart key fob just needs to be reset in order to work properly.
To do this, you’ll want to hold your fob up to your vehicle’s ignition, press and hold the small button on your fob with the lock symbol for three seconds, and watch for your dashboard lights to flash. If you have done this correctly, and all your fob needed was a reset in order to work, then you have successfully fixed the problem and your smart key fob is really to go.
6. Reason Unknown
If you have tried all of the above and your key fob still isn’t working, then the problem may be due to an unknown reason. In this case, you will need to take your fob to a Kia dealer or locksmith to have them take a look at it.
What If My Kia Key Fob isn’t Working and My Car is Locked?
If your Kia key fob isn’t working and your car is locked, don’t worry! You can still get into your car by using a few simple tricks. Let’s take a look at how to do it below.
1. Use Your Fob’s Mechanical Key
The first thing you will want to try is using the mechanical key that came with your car. This key is usually hidden inside the key fob, and can be used to unlock the door if the remote isn’t working.
To use your mechanical key, you will need to find the small metal or plastic piece on the bottom of the fob. Once you have found it, simply jiggle and pull that piece until a metal key slips out.
Insert that key into the key slot in the driver’s car door handle to unlock it like normal.
Once you are inside the vehicle, you’ll be able to try resetting your car key fob using the ignition button, as mentioned earlier in this article.
2. Change the Battery
What if you realize that your mechanical key is missing? If this is the case, then the best way to get into your Kia vehicle is to change the remote’s battery.
To do this, you will need to remove the back cover of the key fob and access the battery compartment. If the battery is tricky to remove, use a flathead screwdriver to insert beside the battery to pop it out. Once you have the old battery out, you can replace it with a new one.
3. Use a Backup Key
And of course, if you have a second key fob or a second backup mechanical key not attached to your fob, now is a great time to use one of them. If you have a backup key, simply insert it into the door lock and turn it to unlock the car like normal. If you don’t have a backup key, then you may need to call a locksmith in order to get into your vehicle.
