Step 1: Gather the Necessary Tools
Before you start the battery replacement process, it’s important to have all the required tools at hand. Here’s what you’ll need:
- New battery (CR1632 or CR2032, depending on your key fob model)
- Small flat-head screwdriver
- Microfiber cloth or soft cloth
Step 2: Locate the Key Fob Slot
To access the key fob battery, you’ll need to locate the key fob slot on your Lexus RX 350. The key fob slot is usually located near the steering column, but it may vary depending on the vehicle’s make and model. Refer to your owner’s manual for the exact location of the key fob slot.
Step 3: Remove the Key Fob Cover
Once you’ve located the key fob slot, use the small flat-head screwdriver to gently pry open the key fob cover. Be careful not to scratch or damage the cover or the key fob itself. Slowly and gently insert the screwdriver into the slot and apply gentle pressure to release the cover. You may need to wiggle the screwdriver slightly to loosen the cover. Once the cover is loose, remove it completely.
Step 4: Remove the Old Battery
With the key fob cover removed, you will now have access to the old battery. Carefully remove the old battery from the key fob using your fingers or the screwdriver, if necessary. Take note of the battery’s orientation and placement to ensure proper installation of the new battery.
Step 5: Clean the Key Fob
While you have the key fob open, it’s a good idea to clean the interior surfaces to remove any dirt or debris. Use a microfiber cloth or a soft cloth to gently wipe the inside of the key fob, paying attention to the buttons and contacts. This will help maintain the key fob’s functionality and prevent any issues caused by dirt or corrosion.
Step 6: Insert the New Battery
Now it’s time to insert the new battery into the key fob. Take the new battery (CR1632 or CR2032, depending on your key fob model) and place it into the designated slot, making sure to match the correct orientation. The positive (+) side of the battery should be facing up.
Step 7: Reattach the Key Fob Cover
With the new battery in place, it’s time to reattach the key fob cover. Align the cover with the key fob and gently press it back into place. You should hear a satisfying click when the cover locks back into position. Give it a gentle tug to ensure it’s securely attached.
Step 8: Test the Key Fob
After replacing the battery and reattaching the cover, it’s important to test the key fob to ensure it’s working properly. Stand near your vehicle and press any button on the key fob. If the key fob is functioning correctly, you should see a response from your vehicle, such as blinking lights or a sound. If not, recheck the battery orientation and make sure the cover is securely attached.
