We recommend checking your specific TTLock lock model's app settings to confirm this feature is supported before purchasing.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does the door sensor come with a battery?\u003c\/h4\u003e\n\u003cp\u003eA: No — the CR2032 coin cell battery is not included due to shipping regulations. You will need to purchase a standard CR2032 3V battery separately, which is widely available at hardware stores, pharmacies, and electronics retailers.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How does the auto-lock feature work with this door sensor?\u003c\/h4\u003e\n\u003cp\u003eA: When paired with a TTLock-compatible smart lock that supports an auto-lock function, the DS2 sensor communicates the door's closed status to the lock, which can then trigger automatic locking. This feature is only available on TTLock locks that natively support auto-lock — please verify your lock's specifications.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the maximum detection gap distance for the door sensor?\u003c\/h4\u003e\n\u003cp\u003eA: The YRHAND DS2 door sensor has a detection distance of less than 22mm, meaning the sensor body and the magnet piece must be within 22mm of each other when the door is closed for reliable open\/closed detection.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How long does the battery last in the DS2 sensor?\u003c\/h4\u003e\n\u003cp\u003eA: Thanks to its ultra-low standby current of under 5µA, the CR2032 battery in the DS2 sensor is designed to last for an extended period under normal usage conditions.
