Frequently asked

We answer everything

What exactly is a "core"? +
The core is the patented magnetic locking mechanism at the heart of the LOCKÜP™ system — the one built into the bracelet. Sold on its own, it lets you equip any device so it becomes compatible with all your LOCKÜP accessories (cords, straps, bracelets, keychains).
Which devices can I install a core on? +
iPhone and Android phones (with or without a compatible case), cameras and action cams, a second phone, plus tools and gear. If the device has a flat surface, you can attach a core to it.
Why buy the cores alone instead of a bundle? +
If you already own a LOCKÜP cord, strap or bracelet, you don't need to rebuy the whole set. The 3-core pack lets you equip 3 devices from $10 each and reuse the accessories you already have.
Is the lock really secure? +
Yes. The core uses N52 neodymium magnets with a 100 lb pull force — the same patented mechanism as the LOCKÜP bracelet. It's built for active lifestyles: sport, biking, travel and crowds.
Are my existing accessories compatible? +
Absolutely. All LOCKÜP™ accessories clip onto the core. That's the point: one system for all your devices and all your accessories.
Shipping and returns? +
Ships in 24-48 h, free international shipping. Returns accepted within 30 days, satisfied or refunded.
