Why does the Toyota Camry trunk open by itself?

The reason why the Toyota Camry trunk opens by itself is that the trunk lock is malfunctioning. When this problem occurs, simply replace the trunk lock. The Toyota Camry is a mid-size sedan under the Toyota brand, with a body length, width, and height of 4885mm, 1840mm, and 1455mm respectively, a wheelbase of 2825mm, and a front-engine, front-wheel-drive layout. The Toyota Camry is equipped with two engines: one is a 2.0L naturally aspirated engine paired with a CVT transmission, with a maximum power of 131kW and a maximum torque of 210Nm; the other is a 2.5L naturally aspirated engine paired with an 8AT transmission, with a maximum power of 154kW and a maximum torque of 250Nm.
In my many years of car repair, the Toyota Camry's trunk opening on its own is quite common. Most of the time, it's an issue with the smart key. If the key is pressed in your pocket, especially if the trunk release button gets stuck, it can easily trigger accidentally. It could also be that the key battery is running low, causing the signal to weaken and the system to react erratically. Additionally, if the trunk's electronic lock control module malfunctions, a short circuit or corrosion can cause the sensor to misinterpret switch commands, which is more likely to happen when the car vibrates or experiences significant temperature changes. I recommend testing with a spare key first; if that doesn't work, take it to a 4S shop to check the lock mechanism and wiring harness wear. Toyota's keyless system design can sometimes be too sensitive, requiring a software upgrade to improve. From a safety perspective, the trunk opening unexpectedly can expose valuables to risk, so always lock and check it immediately after parking.
A while ago, the trunk of my Camry suddenly opened at a gas station, and I almost lost some items. Later, I found out it was because the key button had worn out and become loose, triggering the trunk with just a slight touch. These smart keys lack protection and are prone to being pressed accidentally when kept in a bag. Toyota's remote system is convenient but has many flaws, and similar issues have been encountered by quite a few owners—like children pressing buttons randomly or the key getting wet, which can also trigger unintended actions. My suggestion is to buy a hard-shell key cover to protect the buttons and avoid storing the key with other loose items. Make it a habit to check the trunk before starting the car. If an issue does occur, pull over in a safe location, lock the car, and try again—always prioritize driving safety.
