how to unlock the rear hatch on 2006 Buick Rendezvous

We can only unlock the rear hatch with the key fob, have I done something to cause this? We normally had been able to open it when you hit the unlock on the fob. Thank you

i have one and there is a separate button on the fob. if not, then there is a release button on the console.

The electric switch inside the hatch went bad on the rendevoux in my shop. It is located inside the hatch. The squeez button on the lid would not operate, nor would the unlock buttons work the lid control. The new switch list for about $30.00. The switch is inside the gate.
some of these modles can be unlocked with a remote control
