Key Fob Battery Maximizing Tips

Taking a few basic precautions day to day helps avoid prematurely draining those tiny but critical power supplies:

• Avoid letting battery levels run down completely before swapping in replacements to sidestep function issues from critically low voltages.
• Check cells yearly or bi-yearly depending on use levels. Run tests unlocking doors at greater distances to help gauge if voltages are dropping before failure.
• Store key fobs indoors rather than keeping in vehicles to limit battery capacity shortening from temperature extremes.
• Reduce pressing unlock buttons excessively which risks functionality glitches or quicker battery rundown from overuse versus conservative operation.

Following those simple habits lets you reliably enjoy carefree keyless entry using your handy fob for years between battery changes.

Hopefully, you now better understand the most common coin cell battery options used across vehicle makes and models for powering keyless entry fobs and remote alarms. Typical lithium CR2032 cells provide the most universal and economical solution for restoration once depletion stops remotes functioning. Following the outlined guidance, drivers can conveniently handle replacing batteries themselves rather

How Temperature Extremes Impact Battery Life

Environmental temperature plays a significant role in determining functional battery lifespan for remote key fobs. Keeping remotes away from cold winter temperatures when parked can dramatically extend the charge held in coin cell batteries.

Heat Also Reduces Life

At the other extreme, leaving key fobs inside hot vehicles bakes the batteries – shortening their ability to hold sufficient voltage. Parking remotes on sunny dashboards also risks reduced capacity over time. Keeping keys in pants pockets or buried in hot purses produces the same negative effects.

Try Storing Remotes Indoors

Maintaining moderate room temperature surroundings whenever possible gives key fob batteries the best longevity. Indoor storage avoids shortening cell life through winter or summer temperature extremes. Any steps limiting environmental stress keeps coins cells operating reliably longer before replacement becomes necessary.
