How to access and start the Lexus NX300 with a flat remote

Model: Lexus NX MK 2, Az20 - Years 2021-2026
Part: Key

In this video, learn how to open and start a Lexus NX300 in an emergency with a flat remote. If the remote battery is dead and you are in a location where you cannot obtain a replacement, you can still enter and start the car. Open the remote and extract the emergency key inside: it is a small blade that allows you to unlock the vehicle using the hidden lock in the driver's door handle; pull it towards you, insert the key, and turn it clockwise. The alarm will sound, which you must deactivate by pressing the Lexus logo on the remote against the engine start button while simultaneously pressing the brake pedal. Press the remote against the start button again, keeping the brake pedal pressed. Now the vehicle has recognised the remote, and you can start the car by pressing the "start" button. To close the door, use the same mechanical system. Replace the remote battery as soon as possible!
