How to adjust the locking sound of the Leiling car?

The Leiling does not have a locking sound; the hazard lights will flash after locking. The 2021 Leiling is a compact car under GAC Toyota, featuring a MacPherson independent front suspension and an E-type multi-link independent rear suspension. In terms of body dimensions, the car measures 4640mm in length, 1780mm in width, and 1455mm in height, with a wheelbase of 2700mm. The transmission system is matched with a 10-speed continuously variable transmission. The Leiling has added a sports kit for the sports version, including front and rear aerodynamic bumpers, a sporty mesh piano black front grille, and exclusive sports-style seats. The gasoline sports version also adopts a low-profile body stance.

I've driven a Levin for three years and tinkered with this. The new Levin models basically don't have a factory setting for lock confirmation beeps, but there's a hidden trick: holding the lock button on the key fob for over 3 seconds triggers the panic alarm. To change the default lock sound, you'll need to modify wiring and add a module, like those cheap OBD lock devices from Taobao that plug into the port under the steering wheel. Make sure to get the Toyota-specific version - after installation, you'll get a 'beep beep' sound every time you lock. I'd recommend not making the sound too loud to avoid disturbing neighbors when returning late at night. Also check the instrument cluster settings under Vehicle Customization - some higher trim models might have a chime toggle option.

Last time I helped my colleague adjust her 2021 Levin Hybrid. Toyota's current eco-design defaults to only flashing lights when locking the car. To get a sound, you need to enter engineering mode: first power on without starting the engine, quickly press the start button twice. Then within five seconds, press the accelerator twice and the brake twice, and immediately after hearing a 'beep' sound, hold the lock button for 10 seconds. This method is prone to failure, so it's better to just go to the 4S shop to have the program updated. The mechanics there can enable the locking beep function in five minutes, charging around a hundred yuan. Personally, I think the light confirmation is sufficient and won't disturb the neighbors.

The locking sound of the Levin depends on the model year. From my experience with models from 2017 to 2023, the Luxury trim before 2019 can be adjusted: press both the unlock and lock buttons on the key for three seconds, and the hazard lights flashing twice indicates the activation of the sound prompt. For newer models, you need to install an additional module. I recommend the third-party Loyal Guardian module, which is quite simple to install yourself. Just remove the OBD cover on the driver's side and plug in the device—it can produce three different sound effects. However, be aware that aftermarket devices might interfere with the circuit; I've encountered issues like wipers acting up. It's best to prioritize the car's original light prompts, and the automatic folding of the side mirrors serves as a confirmation signal.
