По поводу моих замков, вот что нашел в руководстве (стр23):
If you do either of the following, no side door or back door can be unlocked with the power door lock switch.
Lock all the side doors and back door with the key or wireless remote control transmitter when all the side doors and back door are closed.
Open the driver’s door or front passenger’s door and move the inside lock knobs of both front doors to the lock position, then close the front doors.
The power door lock switch can be reset in the following ways.
Turn the ignition key to “ON”.
Unlock all the side doors and back door with the key or wireless remote control transmitter.
Unlock the driver’s door or front passenger’s door with the inside lock knob, and then unlock all the side doors and back door with the power door lock switch.
This unlocking protection with the power door lock switch can be disabled. For details, contact your Toyota dealer.
Т.е. это нормальное функционирование замков. Но оно может быть изменено, с помощью дилерского сканера.
