Have you ever wondered what the red button on your car key fob is for? Most people don’t, and they may go years without even using it. However, it’s essential to know that these key fobs, with features like buttons to lock your car, open the trunk, and for emergencies, can sometimes malfunction due to a faulty battery. This can be quite a hassle to deal with, especially when the key is more than a year old. The good news is that you can save yourself from spending $80 to $200 by replacing the battery yourself without damaging your key fob. In this article, I will guide you through the step-by-step process of replacing the battery in your key fob so that you can continue to use it conveniently.
Before we begin, you will need three things: your key fob, a Philips head screwdriver, and a drop of WD-40. It’s important to remove the key from your key ring temporarily while performing the battery replacement surgery to avoid any inconvenience.
Step 1: Unscrewing the Key Fob
Use a perfectly fitted Phillips head screwdriver to loosen the small screw on the back of the key fob. It’s crucial to avoid applying excessive pressure, as this can lead to the screw getting stripped. To make this step easier, apply a drop of WD-40 on the screw and let it sit overnight before attempting to unscrew it to avoid any corrosion-related issues.
Step 2: Replacing the Battery
Once you’ve successfully unscrewed the key fob, carefully open the back of the fob. Inside, you’ll find the battery that needs to be replaced. Gently pop out the old battery and replace it with an equivalent new one. Ensure the battery is properly placed, then reassemble the key fob.
Testing the Key Fob
After reassembling the key fob, test it to see if it works by locking and unlocking your car. If the replacement was successful, the key fob should function seamlessly, allowing you to use it with ease.
By following these simple steps, you can save yourself both time and money by not having to take your key fob to a professional for a battery replacement. With a few basic tools and a little patience, you can have your key fob working like new again in no time.
So, the next time your key fob starts acting up due to a weak battery, remember that you can handle the situation yourself with just a few simple steps. Enjoy the convenience of unlocking and locking your car with the touch of a button without the added expense of professional repairs.
