How do you open the trunk on buick rendezvous without the remote?

To open the trunk of a Buick Rendezvous without the remote, locate the trunk release button inside the vehicle, typically found on the driver's side near the door or on the dashboard. You can also manually unlock the trunk using the key if your model has a keyhole on the trunk itself. If those options are unavailable, you can access the trunk through the rear seats by folding them down to reach the trunk latch directly.
