Some Additional Tips for Maintaining Your Car Key Battery

The average lifespan of your key battery is 3-5 years. However, if you use your key frequently or live in extreme conditions, the battery needs to be replaced sooner.

Avoid dropping your key fob: Make sure to avoid key ore frequently as it damages the key fob and potentially drains the battery faster

Keep spare batteries on hand: It is always a good idea to have spare batteries for your key fob, especially if you frequently use it or are planning a long trip. This will prevent any kind of unexpected inconvenience in case the battery dies while you are away from home.
