Still have a question
Read Our FAQ!
Q1: Will wind, rain, or cats trigger constant alarms?
A: No. A dual-trigger system filters false alerts. Minor movement gives 3 short beeps, while only sustained vibration or strong impact activates the full 110dB alarm-avoiding nuisance noise in shared spaces.
Q2: Could I damage my brake disc if I
forget the lock?
A: No. Each lock includes a bright reminder cable linking the lock to your handlebar. It provides instant visual notice before riding, preventing accidental damage and offering safer use than locks without reminders.
Q3: Will rain or salt air cause rust or
short circuits?
A: No. The body uses marine-grade aluminum with anti-corrosion coatings, while the alarm module is sealed to IP67. It resists rain and coastal humidity, ensuring smooth mechanics and reliable electronic response.
Q4: Will I know when the battery is low?
A: Yes. When battery voltage drops, the lock emits repeated soft beeps upon locking. This low-power alert reminds you in time to replace the battery and maintain uninterrupted protection.
Q5: Do I need a key every time I lock it?
A: No. Simply press the lock cylinder to secure it and activate the alarm-no key needed. A key is only required for unlocking, making it quick and convenient, especially in rain or a hurry.
