Touch Sensor and Lock Switches
WARNING: This page is about a different car, the 2010 Acura TL and 2009 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.
The touch sensors and lock switches are built into the driver's and front passenger's door outer handles. To operate the door locks without the built-in key while carrying the remote, grip the door outer handle to unlock the doors and press the lock switch on the door outer handle to lock the doors.
