If the battery of the LinkU smart lock suddenly dies, you still have a few ways to get the door open
🔑 1. Use the Mechanical Key (Backup Key)
a traditional mechanical key override.
🔹 You insert the physical key into the hidden keyhole and turn it to unlock the door manually.
👉 This is the standard manual backup for when batteries are dead.

The mechanical key is kept somewhere safe but accessible (on your keyring or in a trusted spot).
You know where the keyhole is (often under a cover flap or panel on the lock).
