Lexus ES250 Alarm Going Off
At the title states, my 2021 ES250’s alarm goes off randomly. I just got the vehicle a week ago and paid for a Lexus service to look at it for a pre purchase inspection and they found no issues, so I bought it. Fast forward to the next day, I hear the alarm randomly going off. I think nothing of it, turn it off, go about my business. 20-30 min later, same thing.. and it keeps happening. I considered taking it back to the Lexus service to look at it, however, it’s about a 3 hour drive for me. I have been taking the fuse out of the fuse box for the horn, and this has stopped the alarm randomly going off, but that is obviously not a practical long term fix. I have replaced the key fob battery, taken the terminals off the battery for a “reset”, did relearn steps on opening/closing all doors, locking and unlocking everything, and still nothing is working.
Has anyone experienced something similar and if anyone can suggest a potential fix? I know I can probably take it to Lexus and have them reset the BCM and clear any flags/codes, which would likely take care of it, but I wanted to see if anyone else had any more suggestions.
