Reduced Range: If the key fob needs you to be closer to the vehicle than normal, it’s a clear indicator that the battery may be dying.

Unresponsiveness: If the lock or unlock functions become sporadic or fail to work completely, it might signal a low battery.

Periodic Functionality: Sometimes, the key might work completely well on one occasion but fail periodic times later.

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

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

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

Place the New Battery: Place the brand-new battery in the same orientation as the previous one. Guarantee the favorable and unfavorable sides align properly-- you don’t wish to reverse it.

Reassemble the Fob: Once the brand-new battery remains in place, click the 2 halves of the fob back together till they are strongly sealed.

Test the Key Fob: Stand a few feet far from your vehicle and test the functionality of the lock and unlock buttons to make sure the replacement was effective.
