The horn honks twice because the module still sees a door or the hood open. Also, that is why the remote start does not work. Get in the vehicle and close all the doors and then start the vehicle and watch the instrument cluster to see if it will tell you what door or the hood is open.

A "double honk" or "horn twice" is a versatile non-verbal signal used by drivers globally, with the meaning depending heavily on the social and geographical context. In a friendly context, two short, light "beeps" are often used as a polite greeting to a neighbor or as a "thank you" to another driver who yielded the right-of-way. In ride-sharing or carpooling, it is the universal "I'm outside" signal to notify a passenger that their ride has arrived. However, in heavy traffic, two quick, sharper honks are used as a "wake-up call" for a distracted driver at a green light who hasn't noticed the signal change. In some professional driving cultures, such as trucking or construction, two honks can signal a specific intent, like "I'm backing up" or "the load is secure." In 2026, as cities move toward stricter noise ordinances to curb "honking culture," peer-to-peer etiquette suggests using the double-honk sparingly and only at a low decibel to avoid being perceived as aggressive or contributing to urban noise pollution.
