How do I stop 2011 Toyota camry alarm, goes off every 6 -8 hours
You will want to pull the relay under the hood. The alarm horn is mounted to the firewall near the brake cylinder/reservoir. The relay is nested in the block of relays adjacent to the LF fender. The relay you're looking for in the row nearest to the fender - should be marked SEC HORN Relay. If you pull this relay, it should stop the annoying alarm. Buy a new relay. That may be causing the trouble.
