What can cause unusually rapid smart-lock battery drain?
Include door resistance in the service request
Describe any grinding, repeated lock attempts, or need to push the door while locking. Do not repeatedly run the motor against resistance as a battery test. Ask support to distinguish network reconnection activity, normal use, and mechanical binding. If batteries are leaking, visibly damaged, or unusually hot, stop troubleshooting and obtain the manufacturer's handling and service guidance.
