Questions and answers
Truck is locked and the battery is dead. How can I open the truck to pop the hood to replace battery?
To unlock a 2008 GMC Sierra and access the hood to replace a dead battery:
1. Unlock the vehicle manually using the key in the driver-side door lock if the battery is dead and the remote does not work.
2. Open the hood by pulling the hood release lever located inside the vehicle, usually under the dashboard on the driver’s side.
3. Go to the front of the vehicle and release the secondary hood latch under the front edge of the hood to fully open it.
4. Locate the battery in the engine compartment (see Engine Compartment Overview for exact location).
5. Replace the dead battery following safe procedures.
Use caution, as batteries contain acid and can emit explosive gas.
