Keyless entry models can recognize the smart key within a range of 2-5 meters, and will unlock the doors only when approaching the driver's side door within 1-2 meters. The automatic locking distance is roughly the same range, though it may vary slightly between different models. Here are the details: 1. Working principle: The car smart key consists of a transmitter, remote central lock control module, and driving authorization system control module, forming a control system with three receivers and related wiring harnesses. This system uses advanced Radio Frequency Identification (RFID) technology to automatically lock/unlock doors by sensing the chip in the smart card carried by the owner. 2. Anti-theft status: When the driver approaches the vehicle within a certain distance, the door locks will automatically open and deactivate the anti-theft system; when the driver leaves the vehicle, the door locks will automatically lock and activate the anti-theft status.

I remember the auto-lock feature on my Sagitar was quite handy. With the key in my pocket, it would click and lock automatically when I walked about 5-6 meters away – roughly the distance from a parking spot to a supermarket entrance. However, signal strength plays a big role; if there are walls or metal objects nearby, it might lock at just 3 meters. I got into the habit of glancing back to check if the car lights flashed to confirm it actually locked. For safety, don’t keep the key too far away, as weak battery power can cause malfunctions. While this feature is convenient for daily use, regularly checking the key’s battery is a must—don’t wait until you’re trying to drive to discover it’s unresponsive. Generally, 5-10 meters is the standard range, but it depends on your Sagitar model’s settings. It’s best to test it a few times when the car is new to get familiar with it.

As an occasional car tinkerer, I've noticed that the Sagitar's auto-lock function operates based on RF sensing between the key and the car. It typically initiates locking when detecting the key moves beyond 5 meters. The system is quite intelligently designed, triggered by signal interruption - for instance, it reacts swiftly if you walk away briskly. Interferences like crowded areas or obstacles may reduce this range. A friendly reminder: don't rely too heavily on it, as unstable signals could cause delayed locking. It's best to develop the habit of manually pressing the lock button. During maintenance, checking the key fob's battery life can prevent surprises, since the distance limitation serves anti-theft security purposes. Testing your car is simple - find an open area and gradually test the steps to confirm the exact locking distance.

In terms of safety, the automatic locking distance is set reasonably. The Sagitar automatically locks between five to six meters, preventing the high risk of forgetting to lock. In crowded places, I avoid staying too far away to prevent theft due to not locking. Signal interruption is the main factor, as the key moving away triggers the protection mechanism. It's recommended to keep the key with you and not leave it too far, especially when parking in remote areas at night. The Sagitar's default settings are reliable, but it's best to test the door's responsiveness weekly. This feature makes daily use worry-free and enhances driving safety.
