The component that powers the key fob for the 2019 GMC Sierra 1500 is a small, coin-shaped cell. Specifically, a CR2032 type battery provides the necessary energy for the remote to function, enabling features such as remote start, door locking/unlocking, and alarm activation/deactivation.
Using the correct cell type is crucial for reliable operation. An incompatible size or voltage can prevent the remote from working correctly, potentially causing inconvenience and limiting access to vehicle features. Vehicle owner’s manuals typically provide this information as part of the vehicle information. Replacing a worn battery promptly ensures that the remote continues to function effectively, maintaining security and convenience.
