Reliable replacement for car key fobs

This pack contains two Battery Guru CR2025 lithium coin cells rated at 3 V. Each cell is intended as a direct replacement when a key fob battery runs low or dies. The pack gives a spare so the remote can be restored quickly without waiting for a separate order.

Stable voltage with minimal self-discharge

Lithium chemistry provides a steady 3 V output across the usable life of the cell. Self-discharge is very low, so the spare battery retains charge during storage. Normal use in a key fob draws only microamps, producing no noticeable heat and requiring no active cooling.

Questions about this item

How do I install the CR2025 battery in my car key fob, and what step do people often miss?

Open the fob case, remove the old cell, and insert the new CR2025 with the positive side facing up; the step many miss is checking the owner's manual to confirm CR2025 is the correct type before fitting it.

When will these CR2025 cells need replacing again?

A fresh CR2025 lithium coin cell typically powers a car key fob for one to three years depending on usage, so expect to replace the pair when range drops or the fob stops responding.
