Frequently Asked Questions
Q: Is the TTLock Door Sensor DS2 compatible with all TTLock smart locks?

Q: Does the TTLock DS2 door sensor work as a standalone alarm device?
A: No — the DS2 must be paired with a compatible TTLock smart device. It communicates over 2.4GHz and works through the TTLock App to deliver real-time open/close notifications and unlock record tracking.
Q: What battery does the TTLock DS2 use, and how long does it last?
A: The sensor runs on a standard CR2032 3V coin cell battery (not included due to shipping restrictions). Thanks to its ultra-low standby current of under 5µA, a single battery typically lasts up to 2 years under normal use.
