Step 2: Remove Old Battery
Using a small flathead screwdriver or a similar tool, gently pry open the key fob along the groove or seam. Be careful not to apply too much force to avoid damaging the casing. Once the key fob is open, locate the old battery inside.
Carefully remove it using the screwdriver or your fingers, ensuring not to scratch or bend any internal components. Dispose of the old battery properly in accordance with local regulations.
Step 3: Check for Correct Battery Type
Before inserting a new battery, verify the correct battery type for your key fob. The type is usually printed on the old battery or indicated inside the key fob casing. Common types include CR2032 or CR2025 lithium coin batteries.
Ensure the replacement battery matches the specifications exactly to guarantee proper functionality. Having the correct battery type is crucial to avoid issues with compatibility or performance.
Step 4: Insert New Battery
Carefully place the new battery into the designated slot inside the key fob. Ensure that the positive (+) side of the battery is facing up, as indicated by the markings inside the fob. Gently press the battery into place, making sure it sits securely without forcing it.
Proper alignment is essential to maintain the electrical connection and ensure the key fob functions correctly. Take care not to touch the battery’s surface excessively to prevent transferring oils from your hands, which could affect its performance.
