Toyota uses a smart dual approach on the outside. The door has a fixed outer handle with a small pad that triggers the electronic lock, but it also adds a small manual button next to it. Toyota explains that the production setup will work as a two step mechanical solution: the first pull cancels the lock, and the second pull opens the door manually, with no need for any electrical power. Toyota also adds a removable section that lets you insert a traditional key, so access stays possible even if the vehicle is fully out of charge.

Toyota applies the same logic inside the cabin, using an approach already seen in modern Lexus models. Riders can open the door electronically with a button, but they can also rely on a mechanical fallback by pulling the interior handle twice. This matters most after a collision where electrical circuits could be damaged. Instead of trapping occupants behind an electronic system that might not respond, the design keeps a simple physical exit option ready. It also signals Toyota’s bigger message with Highlander EV 2027: embrace advanced tech, but never remove the reliable basics when human safety is on the line.
