Toyota Repair: How to Change the Door Lock Mode If you own any recent Toyota model that has power locks and an automatic transmission, you have the ability to change the sequence for the locking and unlocking of the doors – as determined by the current mode.Start switch for auto-door system Mode 1 – This mode connects the shift position with automatic door locking – but notably not unlocking. When the key is in the ignition and in the “On” position, and when all doors are shut, they will automatically lock when you move the shift lever out of “Park.” Mode 2 – This mode simply turns off the feature. Automatic locking and unlocking will be nonoperational. Mode 3 – Similarly to Mode 1, this mode ties both locking and unlocking of doors with the shift position. With the key in the “On” position and with all doors shut, you will auto-lock them whenever you move the shift lever from “Park.” In turn, the doors will auto-unlock whenever you bring the shift lever back to “Park.” Mode 4 – This mode connects not just the shift position but also the key position to the automatic locking and unlocking system. With the key set to “On” and all of the doors shut, you will auto-lock the doors when you move out of “Park” with the shift lever. In turn, all the doors will auto-unlock when you turn the key to “Off” while the shift lever is in “Park.” You now know how to switch your Toyota car into any of the four different modes for automatic locking and unlocking – one of which (Mode 2) shuts it off completely, if that is your preference. Again, although not a Toyota repair, this project will allow you to have better control of the car and to fix the situation if you are frustrated by the way that this automatic feature is currently configured.
