The locking sound of a Corolla is activated by a relay in the anti-theft controller. If there is no sound, it may be due to a loose wire or a malfunction, which requires inspection and repair at a 4S shop. Below are specific details about the Corolla: Powertrain: The Corolla is equipped with a newly developed inline 4-cylinder 1.8L engine (2ZR type) featuring dual VVT-i technology. Paired with either a 6-speed manual transmission or a 4-speed automatic transmission, it delivers a maximum power of 100kW/6000rpm and a peak torque of 175N·m/4400rpm. Features: The Corolla comes with a one-touch ignition system typically found in higher-end models, as well as VSC, a rearview camera system, dual-zone automatic climate control, a multifunction steering wheel, a multi-disc CD player, and MP3 compatibility. Interior: The door panels are made of soft-touch materials, and the silver interior door handles add a stylish touch. The upper section of the dashboard uses high-quality soft-touch materials for a pleasant feel.

I remember the first time I researched the Corolla's lock sound was while waiting at a car wash. By holding down the 'lock' and 'unlock' buttons on the remote key for about 5 seconds, it was done. The car lights flashed twice to indicate a successful setup, and after that, it beeped once every time it was locked. Older models might require in-car operation: with the power off, press the brake pedal twice, press the hazard light button twice, and then turn the key to power on to hear the sound change. To cancel the sound, just repeat the long-press operation on the key, which is very convenient. However, it's important to note that some country versions have this feature disabled. My Japanese-spec car could use it, but my friend's Thai-spec car didn't have the sound option.

Just helped my neighbor aunt adjust her 2021 Corolla last week, it's actually super simple: Sit in the car and close the door, don't step on the brake, just press the start button twice to power on (dashboard lights up will do). Then simultaneously hold down the lock and unlock buttons for three seconds, and you'll hear a 'beep beep' prompt sound. Get out and try pressing the lock button, and you'll immediately hear a crisp 'chirp' sound. Auntie said this feature is especially useful for parking in underground garages, as she can rely on the sound to confirm when her presbyopia makes it hard to see the flashing lights. If you can't get it to work, it might be a configuration issue—the Pioneer edition might not have this feature.

Adjusting the car lock sound is actually like an Easter egg in games: After turning off the engine, hold down the lock and unlock buttons on the remote key. If the car lights flash twice within five seconds, it means the adjustment is successful. I run an auto repair shop and often encounter customers complaining about the sound being too loud. The method to cancel it is the same. Last year, while helping a customer unlock hidden features, I discovered that high-end Corolla models can even change the sound type using a diagnostic computer, but ordinary car owners don’t need to bother with it. Remember not to let the buttons get wet when pressing the key for a long time in the rain. Last time, I saw a guy press the key into a puddle and burn out the circuit board.
