Identifying Your GM Key Fob Type

GM uses a variety of key fobs across its models. Identifying your key fob type is the first step. Common types include the switchblade key, the traditional key fob with separate key, and the smart key. Knowing your key fob type will help you locate the correct battery compartment.

Locating the Battery Compartment

The battery compartment’s location varies depending on the fob type. Some fobs have a release button or slot, while others might require a small flathead screwdriver to pry open. Consult your owner’s manual for specific instructions.

Step-by-Step Guide to Changing Your GM Key Fob Battery

Here’s a general guide, but remember to consult your owner’s manual for model-specific instructions:

Gather Your Tools: You’ll need a small flathead screwdriver or a similar tool to pry open the key fob and a replacement battery (usually a CR2032).
Locate the Release: Look for a small button, slot, or indentation on the fob.
Open the Fob: If there’s a release button, press it. If not, use the flathead screwdriver to carefully pry the fob open at the designated seam.
Identify and Remove the Old Battery: Note the battery’s orientation (positive (+) and negative (-) sides). Carefully remove the old battery using the screwdriver or your fingernail.
