In some implementations, systems and techniques are described to automatically unlock a front door of a property in response to detecting an alarm signal indicating an emergency at or near a property. Data indicating occurrence of an emergency condition at a property is initially obtained. A lock configuration for an electronic lock of the property is determined. An unlock instruction is generated for the electronic lock based on the determined lock configuration for the electronic lock. The unlock instruction is transmitted to the electronic lock such that, when the unlock instruction is received by the electronic lock, the electronic lock is unlocked according to the unlock instruction.
