How To Turn Off Seat Belt Buzzer Alarm On Lexus Cars

The seat belt alarm warning beeper is a useful security feature designed to remind car passengers to fasten their seat belts. However, in some cases, you may feel like it is a bit excessive and that you are an adult who doesn’t need a constant reminder to buckle up. Fortunately, Lexus provided an easy way to disable the seat belt buzzer reminder that doesn’t require any special tools or programming equipment. And it only takes a few minutes to complete.

Method 2

If the above method didn’t work, try to turn off your car twice in Step # 2. Next, repeat the rest of the steps just like in the first method to turn off the seatbelt beeper. If it still doesn’t work try both methods a few times and make sure your timing is correct.
