The following steps provide a general guideline. Consult your owner’s manual for specific instructions for your car model.

Locate the Battery Compartment: This is usually located on the back or side of the fob and might be hidden behind a small panel or release button. Some key fobs require you to use the valet key to open the fob. If you’re unsure how to access the battery compartment, refer to your owner’s manual or search online for instructions specific to your car make and model.

If you are having difficulty with any of these steps, consider consulting a professional locksmith or your car dealership. Although replacing the battery is a simple task, incorrect installation could damage the key fob.
