Our LITELOK Twins can be operated from the same set of keys. However, if you want 3 or more LITELOKs, or 2 LITELOK ONE Wearables to operate from the same set of keys then please add the following note on the cart page: “Please key alike all locks in this order” It is worth noting that because this would be a custom order, there is a lead time of 7 working days and we would be unable to accept returns or issue refunds as a consequence.
