Reduced Range: If the key fob requires you to be closer to the vehicle than normal, it's a clear sign that the battery might be passing away.

Unresponsiveness: If the lock or unlock functions become erratic or stop working to work completely, it may indicate a low battery.

Periodic Functionality: Sometimes, the key may work completely well on one event but stop working periodic times later.

Physical Wear: If the key fob reveals signs of damage or wear, it might affect the battery container, jeopardizing its connection.

Warning Lights: Some cars have control panel indications that signal the user when the key fob battery is low.

Open Your Key Fob: Most key fobs have a notch or seam. Examine the fob carefully, then use a flathead screwdriver or coin to pry open the fob carefully.

Eliminate the Old Battery: Take note of how the battery is seated. Get rid of the old battery by carefully pushing it out from the edge.

Insert the New Battery: Place the new battery in the exact same orientation as the previous one. Guarantee the positive and unfavorable sides line up correctly-- you do not wish to reverse it.

Reassemble the Fob: Once the new battery is in place, click the two halves of the fob back together until they are securely sealed.

Evaluate the Key Fob: Stand a few feet far from your vehicle and test the performance of the lock and unlock buttons to ensure the replacement succeeded.
