Gathering Your Supplies
Before you dive into replacing the battery, make sure you have the right tools and materials on hand:
- A new CR2032 battery: This is the standard battery used in most Toyota key fobs, including the 2019 Tundra. You can find these batteries at most convenience stores, electronics retailers, and even online.
- A small flathead screwdriver: This is needed to pry open the key fob.
- A clean, dry cloth: This will help you keep the key fob clean during the process.
Identifying the Battery Compartment
The first step is to locate the battery compartment on your key fob. It’s usually on the back of the fob, but the exact location may vary slightly depending on the specific model. Look for a small seam or a small button that you can press to release the back cover.
Opening the Key Fob
Once you’ve identified the battery compartment, use your flathead screwdriver to gently pry open the back cover. Be careful not to apply too much force, as you don’t want to damage the key fob. The back cover should pop off easily, revealing the battery inside.
Removing the Old Battery
The old battery is usually held in place by a small metal spring clip. Carefully lift the battery out of the compartment, making sure not to touch the metal contacts on the battery. Dispose of the old battery properly, as they contain hazardous materials.
Installing the New Battery
Take your new CR2032 battery and align the positive (+) side with the positive terminal in the battery compartment. Gently press the battery into place until it clicks securely. The spring clip should hold the battery in place.
Closing the Key Fob
Once the new battery is installed, carefully align the back cover of the key fob with the front part and press it firmly until it snaps back into place. You should hear a click when the cover is securely closed.
Testing the Key Fob
With the battery replaced, it’s time to test the key fob to make sure it’s working properly. Press the lock, unlock, and panic buttons to ensure they respond. If the key fob is working correctly, you’re all set!
Tips for Key Fob Battery Life
To maximize the life of your key fob battery, here are a few tips:
- Avoid extreme temperatures: Heat and cold can shorten the lifespan of the battery. Keep your key fob out of direct sunlight and extreme temperatures.
- Don’t leave it in your pocket with metal objects: Metal objects can drain the battery faster. Keep your key fob separate from coins, keys, and other metal items.
- Replace the battery regularly: Even if the battery is still working, it’s a good idea to replace it every year or two to ensure optimal performance.
Troubleshooting Battery Issues
If you’ve replaced the battery and your key fob still isn’t working, there may be other issues at play. Here are some troubleshooting tips:
- Check the battery contacts: Make sure the battery contacts are clean and free of corrosion. Use a cotton swab dipped in rubbing alcohol to clean the contacts if necessary.
- Check the key fob’s programming: If the key fob was programmed to your truck, it may need to be reprogrammed after the battery change. Consult your owner’s manual or contact a Toyota dealership for instructions on reprogramming.
- Check the vehicle’s battery: A weak vehicle battery can also affect the key fob’s range and functionality. Make sure your truck’s battery is in good condition.
