Cadillac 2006 XLR - Manual (Page 62)

If power to the vehicle or the keyless access transmitter
is lost, there are two ways to open the door.
If you are inside the vehicle, use the door release
handle located on the floor next to each seat. Pull the
handle up to unlock and unlatch the door.
If you are outside the vehicle, there is a door release
tab in the trunk. The tab is located behind a panel on
the driver’s side of the trunk. Pull the handle to
unlock and unlatch the driver’s door. See Trunk on
page 2-12 for information on opening the trunk during
a loss of power.
