Gather Your Tools
Before we begin, it’s essential to gather the necessary tools. Here’s a quick list:
- New CR1620 battery
- Flathead screwdriver
- Precision screwdriver (optional)
- Pen (as an alternative)
Once you have these items, you’re ready to proceed.
Opening the Key Fob
First, open the key by flipping it out. This action will reveal a small groove on the inside. You need to push up on this part to create a separation, allowing you to remove the bottom part of the fob.
Using Your Fingers
If the fob is not too tight, you can use your fingers to create the separation. Hold the top part and push up on the groove. It should come apart with minimal force.
Using a Flathead Screwdriver
If the fob is too tight to open with your fingers, use a flathead screwdriver. Hold the top part of the fob and insert the screwdriver into the groove. Apply gentle pressure to push it up and separate the two halves.
Removing the Old Battery
Once the fob is open, you will see the battery. It might be in there pretty tight, but don’t worry. There are two methods to remove it without damaging the fob.
Using a Precision Screwdriver
If you have a precision screwdriver, locate the small arrow on the bottom right corner of the battery compartment. Insert the screwdriver and rock it gently to pry the battery out.
Using a Pen
If you don’t have a precision screwdriver, you can use a pen. Insert the pen into the same corner and apply pressure to pry the battery out. You might get a little ink on the battery, but that’s okay.
Inserting the New Battery
Now that the old battery is out, it’s time to insert the new one. Make sure the side with the brand and battery information faces down. This is the positive side.
Follow these steps:
- Hold the battery with the positive side facing up.
- Slide the top part of the battery into the compartment first.
- Push the bottom part down until it clicks into place.
Reassembling the Key Fob
With the new battery in place, it’s time to reassemble the key fob. Align the two halves of the fob and press them together until they click.
Your key fob is now ready to use with a fresh battery! Test the buttons to ensure everything is working correctly.
