Toyota CHR doors do not automatically lock after exiting the vehicle. Under factory settings, the C-HR is not equipped with an automatic locking function. If you wish to enable this feature, it can only be achieved through aftermarket installation. Methods to enable automatic locking: There are three types of car doors: forward-opening doors, reverse-opening doors, and horizontally sliding doors. Forward-opening doors can still be closed by the pressure of airflow while the car is moving, making them safer and more convenient for the driver to observe the rear when reversing, hence widely adopted. Reverse-opening doors, if not tightly closed while driving, may be forced open by oncoming airflow, thus used less frequently, generally only to improve entry/exit convenience or for ceremonial purposes. Horizontally sliding doors have the advantage of being able to fully open even when the side of the car is close to an obstacle. Via OBD interface: Currently, the most common method in the market for Toyota C-HR to add an automatic locking function is by directly plugging into the OBD interface to enable the locking feature. It is usually plug-and-play, requiring no wiring harness connection or system matching, which greatly enhances the convenience for vehicle owners during use.

As a Toyota C-HR owner, I frequently use the walk-away auto lock feature, which is really convenient. Every time I get out of the car and walk a few steps away, about three or four meters, the doors automatically lock without me having to take out the key or press any buttons. This function is achieved through the smart key system—when the key is a certain distance from the car, the sensors automatically lock it. The benefit is that it eliminates the hassle of forgetting to lock the car. For example, when I'm in a hurry to go grocery shopping, I don't have to worry about the doors being unlocked and potential security risks. However, there are two things to note: first, the key must be on your person; if left in the car, it prevents accidental locking. Second, there might be a setup requirement—you may need to enable the auto-lock option in the central control screen. I had to configure it once when I bought the car. Overall, this feature saves a lot of time in daily use, and I feel the C-HR's design is very thoughtful. I recommend new owners try it out. If it doesn't respond, check if the key battery is low—regular maintenance can prevent unexpected issues.

From a technical perspective, the CH-R's walk-away auto-lock feature relies on collaboration between the smart key and vehicle sensors. When the person carrying the key moves beyond a preset distance (typically around 3-5 meters), the sensors detect signal weakening and trigger the door-locking mechanism. This system utilizes RFID technology, eliminating manual operation while enhancing anti-theft performance. The advantages are clear: it prevents the risk of forgetting to lock and saves time. As for drawbacks, signal interference environments (such as underground parking garages) may cause delays or misjudgments. I recommend that owners develop the habit of taking a step back to check if doors are locked rather than relying entirely on the system. Additionally, verify whether the auto-lock setting is enabled through the dashboard menu. Replacing old batteries with new ones ensures stability. Considering the overall experience, this feature is a highlight for modern vehicles, but don't overlook the importance of regular maintenance.

As an average driver, I find the Toyota C-HR's walk-away auto-lock feature quite reliable. When I walk a few steps away after exiting the car, it locks automatically, which is both convenient and secure. This function operates via key fob detection, automatically engaging the locks when the preset distance is reached, eliminating the issue of forgetting to press the lock button. The main advantage is reduced theft risk, especially providing peace of mind when parking in unfamiliar locations. One important note: ensure the key isn't left on the seat, otherwise the system won't activate. For new users, it's advisable to test whether the setting is enabled and listen for the locking sound confirmation in noisy environments. Overall, it significantly improves daily convenience.
