Task Step Guide

Step 1: Identify the Type of Key Fob and Battery

Different Toyota models use different types of key fobs. Commonly, Toyota key fobs use CR2032 batteries, but it's essential to check your owner's manual to confirm.

Step 2: Gather Necessary Tools

Before you begin, gather the following tools:

• A small flat-head screwdriver or a coin

• A new CR2032 battery

Step 3: Open the Key Fob

Use the small flat-head screwdriver or a coin to pry open the key fob. Insert the tool into the seam where the two halves of the fob meet and twist gently. Be careful not to apply too much force, as you could damage the fob.

Step 4: Remove the Old Battery

Once the key fob is open, locate the old battery. It should be easy to spot and usually held in place by a small clip or bracket. Carefully lift the battery out, noting the orientation of the positive and negative sides.

Step 5: Insert the New Battery

Take your new CR2032 battery and insert it into the slot, ensuring that it is oriented the same way as the old battery. The positive side (marked with a "+" sign) should face up.

Step 6: Snap the Key Fob Back Together

Align the two halves of the key fob and press them together until they snap back into place. Ensure there are no gaps and that the fob is securely closed.

Step 7: Test Your Key Fob

Before you consider the job done, test your key fob to make sure it works. Test all the buttons to confirm they respond correctly.
