Replacing the battery in your 1998 Lexus key fob is a quick and easy process that can save you time and money. This guide will walk you through each step, ensuring you can get back on the road with a fully functioning key fob in no time.
Understanding Your 1998 Lexus Key Fob
Before diving into the replacement process, it’s helpful to understand the type of key fob your 1998 Lexus uses. Lexus models from this era typically employed a simple, yet effective, key fob design. These fobs often feature a single button for locking and unlocking the doors and trunk, and a separate key blade for manual entry. Knowing the specific type of key fob you have can make finding the correct replacement battery a breeze.
Identifying the Correct Battery
The most common battery used in 1998 Lexus key fobs is the CR2016 3V lithium coin battery. This battery is readily available at most electronics stores, pharmacies, and online retailers. However, it’s always best to double-check your owner’s manual or consult a Lexus dealership to confirm the exact battery type for your specific model.
How to Replace the 1998 Lexus Key Fob Battery
Replacing the battery is a straightforward process that you can do yourself with just a few simple tools. Here’s a step-by-step guide:
- Gather your tools: You’ll need a small flathead screwdriver or a similar tool to pry open the key fob casing. A small container to hold the battery and any small parts can also be helpful.
- Locate the seam: Examine your key fob and find the small seam or notch where the two halves of the casing join. This is usually located along the side or back of the fob.
- Open the key fob: Carefully insert the flathead screwdriver into the seam and gently pry the two halves of the casing apart. Be careful not to apply too much force, as this could damage the fob.
- Remove the old battery: Once the key fob is open, you should see the CR2016 battery. Gently pry it out of its compartment using your screwdriver or fingernail.
- Insert the new battery: Place the new CR2016 battery into the compartment, making sure the positive (+) side is facing up. You should hear a slight click when the battery is properly seated.
- Reassemble the key fob: Align the two halves of the casing and press them together until they snap shut. Test the buttons to ensure the key fob is functioning correctly.
Troubleshooting Tips
If your key fob isn’t working after replacing the battery, here are a few things to check:
- Battery Orientation: Ensure the battery is inserted correctly with the positive (+) side facing up.
- Clean Contacts: Use a cotton swab and rubbing alcohol to clean the battery contacts inside the key fob. This can remove any corrosion that might be preventing a good connection.
- Key Fob Reprogramming: In some rare cases, you may need to reprogram your key fob after replacing the battery. Consult your owner’s manual or a Lexus dealership for instructions on how to do this.
