I searched on 89747-48020 and found this: 8974748020 - Lexus Buzzer. Clearance warning, no. 2; wireless door lock | Lexus Parts & Accessories Online www.amazon.com/Toyota-89747-48020-Wireless-Door-Buzzer/dp/B018MHBDYO
Not seeing the fender liner there, did you strike or hit something? Did any lights illuminate? How long has the wiring been dangling? Does the Prius perform the same as it did prior to finding this?
Has anyone flipped the switch under your steering wheel, where the 'smart' key system can be disabled to save battery drain?
I tried unlocking the doors and a beeping sound is coming from the dangling box so you guys were right! No idea where the proper place to put the box is so it won't dangle. Also, my smart key button under steering wheel was depressed so I pushed it and now my smart key works AGAIN! Thank you thank you thank you! My 2 year old must have pushed it.
