- The front of the key fob should now be facing downward.
- In the slot on the side of the fob, insert the point of a small flathead screwdriver (opposite the side that houses the mechanical key)
- Take the key fob’s case off with little pressure.
- Delete the previous battery.

How is a key fob disassembled?
Key fobs make it simple to get into your car. The key fob’s capacity to operate remote controls will be lost as soon as the battery is low or dead. Key fobs make it simpler to enter cars. With this device, opening the doors and the trunk or tailgate is simpler than before. Some have the key integrated right in, while others are independent from the key. Only the fob’s ability to control remote functions requires the battery. The battery is simple to replace and is available at any supermarket, drugstore, or retailer of car parts.
Step 1:
Activate your key fob. Typically, all you need is a firm fingernail to pry open your key fob. If it doesn’t work, carefully pry it open with a small flathead screwdriver.
Pry lightly from multiple places all around the key fob to prevent cracking the shell.
The remote must first be separated from the key in some all-in-one key fob/key combinations, as seen below. The process for changing batteries is the same.
Step 2:
the name of your battery. If you haven’t already bought a replacement battery, you can see the battery type and number printed on it now that the fob has been opened.
Step 3:
Make sure the fob shell completely snaps together as you carefully reassemble it.
Key fobs can they be fixed?
While you might be able to repair a damaged fob, there are instances when it is just simpler to replace it. A replacement fob can cost as little as $50 depending on the make and model of your car, yet they may cost more in other instances and end up costing you quite a bit.
Why won’t my Kia key fob work?
The battery that powers your key fob is most likely to blame if it stops functioning. Typically, watch-sized batteries that are skillfully hidden inside the casing of key fobs are used. With a little screwdriver or key, you can easily peel the key fob apart and change the battery by yourself.
Finding out what kind of batteries they require and keeping one on handeither at home or in your glove boxis a good idea. If you have the batteries on hand, it will save you some effort and they are cheap, costing between $5 and $25. Finding them is not difficult. They ought to be in stock at your local Kia dealer. Additionally, you can locate them in grocery stores, hardware stores, and other stores. Make sure you choose the proper kind. The voltage output of many of these batteries varies despite their similar appearance.
Key fobs do they get old?
The batteries in all of these remote controls, including the proximity-style and push-button start fobs, periodically need to be changed. It is the most frequent cause of fob failure.
A typical internal malfunction in the fobs used by many GM vehicles can cause one button or the entire remote to become inoperable, while button contacts in nearly any fob can wear out. It’s a rather simple remedy.
These remote controls have a few recognized flaws, however it must be stated that they rarely malfunction completely without suffering some sort of trauma.
Even though wriggling or squeezing the buttons occasionally makes it work, the contacts inside the buttons do eventually wear out.
You might need to resync the remote if it has been inactive for a while (due to a dead battery), in which case you should hold down the “Lock” and “Unlock” buttons at the same time for a few seconds.
The battery in remotes and fobs can be accessed in a number of ways. Some feature a battery door, some utilize one or more tiny screws, and some call for partial disassembly. To separate the halves, there is typically a slot that can be used with a coin, screwdriver, or even a kitchen knife. If there isn’t a slot, slowly wedge them apart with the proper tool.
There might be a little loose part inside that we’ll need in a moment, so open it over a suitable work surface like a table or workbench.
We can see the circuit board and battery when the fob has been split open. Near the center of the image, if you look closely, you can see that the metal clip that holds the battery is not positioned as it should be.
The metal tab serves as both the positive conductor for the remote and a means of holding the battery in place. The wiring on the circuit board is connected by the two tiny tabs where they pass through the board. One button might be the only one affected if only one breaks off.
The remote’s little metal fingers that stick out through the circuit board are more visible with the clip taken off. When the battery is placed, the central “finger” presses the battery down to hold it in place and establish electrical contact on both the top and bottom, placing additional spring pressure on these tabs.
The negative contact is represented by the grid on the board. It makes contact with the bottom center of the coin cell. Both these and the button contacts that appear similar on the back of the board can be cleaned using a pencil eraser.
There are a few things to consider before soldering. First, use caution when using the iron because electronics don’t appreciate too much heat. Instead of using the iron, heat the tab to melt the solder on it. Make sure the tab is hot enough for the solder to flow into the board’s holes and depressions. Do not overuse solder, and make sure to use solder made for electronics rather than plumbing. A 1 mm diameter rosin core is what I favor.
Do not take pictures while soldering; this is not the finest repair I have ever made. But the fob had been mended, and it ought to stay that way. The owner was quite happy not to have to choose between the cost of replacement, reprogramming, or losing her keyless entry feature when full functionality was restored.
