Mazda6 horn alarm after locking the car is mainly caused by alarm system malfunction. Here are the relevant explanations: 1. Possible causes: The built-in anti-theft system has excessive sensitivity settings, loose sensors under the engine hood, short circuits in the wiring, or aging control key contacts or overly soft springs. 2. Overview: The Mazda6 is the latest product launched by Mazda in the 21st century, a mid-to-high-end sedan introduced at the 2001 Tokyo Motor Show. Since its launch, it has won over 30 awards in 20 countries worldwide. On April 10, 2003, the Mazda6 came to China and, with its extraordinary appearance and handling, won the title of "King of Corners" for the year.

My Mazda6's horn suddenly went off randomly after locking the car, which was really annoying. Based on my experience, common causes include doors not being properly closed, a loose trunk latch, or an improperly positioned hood, which can make the anti-theft system mistakenly think there's a break-in. If the key is still inside the car or nearby causing interference, the system can go crazy; sensors clogged with dust or misaligned can also be a factor. Last time I encountered this, I first checked if all doors were tightly closed and gave the trunk a firm push—sometimes that stops it. Low battery voltage or aging wiring can also trigger the alarm, and letting it keep blaring will drain the battery and attract thieves, so getting it fixed ASAP is the way to go. I recommend developing the habit of checking if the lights flash after locking the car, and regular maintenance of the anti-theft system can prevent trouble. If it keeps happening, check the fuses or control module—don't skimp on the small cost.
