Lexus GS 450h 2006 Towing And Road Service Manual page 15

If there is a problem with the transponder or the battery in the key fob a display should
appear in the middle of the instrument panel like the one shown in Figure 16.

If this is occurring on a vehicle you encounter, ensure the vehicle is in "PARK", hold the
key fob against the chrome ring around the "ENGINE START STOP" button, depress the
brake pedal then depress the "ENGINE START STOP" button to start the vehicle. If the
vehicle starts, ensure the operator knows to hold the key fob against the chrome ring to
start the vehicle and then direct the operator to take the vehicle to the closest Lexus dealer
to have the problem repaired.
If there is a problem with the keyless entry system, there is a key cylinder in the driver's
side door to insert the removable metal key from the end of the key fob into to unlock the
vehicle.
The design of the key proximity sensor system with this vehicle makes it virtually
impossible to lock your keys in the vehicle. After extensive attempts to lock keys inside
this vehicle we found the only way to do so was to have a dead battery in the key fob,
turn off the valet switch in the glove box for the power trunk release, then open the trunk
with the metal key and place the key inside the trunk. If someone actually locks their
keys in a 2006 Lexus GS series vehicle, the recommended entry method would be to
carefully wedge the upper rear corner of the right front door away from the body and
using a long reach tool, unlock the door.
