What is the reason for the Audi Q5L's alarm going off without reason after locking the car?

Audi Q5's alarm sounding after locking the car may be due to doors not being closed tightly, or interference signals from similar alarms of other vehicles. Below is an introduction to the Audi Q5:1. Introduction: It is a dynamic and versatile SUV. With its excellent performance and technical advantages, the Michelin Pilot Preceda PP2 high-performance sports tire has recently become the original equipment tire for the premium mid-size SUV Audi Q5.2. Features: It perfectly combines the body design of a sports car, efficient power and sensitive handling, the off-road safety performance of an SUV, and the excellent comfort and flexible interior space of a station wagon, continuing the advantages of the third-generation top SUV Audi Q7. The powerful green efficient engine, quattro all-wheel drive system, and sensitive driving mechanism make it effortless whether driving on the road or off-road. The application of new technologies such as the 7-speed dual-clutch Stronic transmission and Audi drive select once again interprets Audi's brand concept of 'Vorsprung durch Technik' (Advancement through Technology).
I've specifically researched the issue of the Audi Q5L's alarm going off for no reason after locking. It's mainly related to the overly sensitive anti-theft system. The ultrasonic sensor inside the vehicle is like an overly nervous security guard - a jacket sliding off the seat or a tissue box tipping over on the dashboard can trigger it. Once I saw a shopping bag from a roadside supermarket being blown by the wind against the car door, and the alarm immediately started wailing. Additionally, if there's poor contact in the door lock mechanism, the system might mistakenly think someone is trying to pick the lock. Another common cause is when the trunk isn't properly closed, especially during rainy days when the rubber seals expand and make it easy for the trunk to appear closed when it's not. For this kind of problem, there's no need to rush to the dealership. First, try securing all loose items in the car before locking it. If the alarm still acts up, hold down the alarm switch near the interior dome light for 10 seconds to force mute it, or have the dealership use their computer to lower the sensor sensitivity.
This situation is likely caused by a minor glitch in the anti-theft system, similar to human infrared sensors. The weirdest case I've encountered was when a leaf got stuck in the window gap - the rustling sound from the wind was mistaken for an intrusion. Some owners even report that static interference on the navigation screen can trigger alarms. My advice: Before locking, check if all four doors and both hoods are properly closed. Don't keep car keys and phones in the same pocket as signal interference can cause issues. Also check under the driver's seat for coins that might be pinching sensor wiring. Many cases show control modules act up when battery voltage drops below 12.6V, especially common in autumn/winter. As last resort, try starting then locking with the spare key - it's like rebooting the anti-theft system.
