Quite simply it didn't work. I checked with the manufacturer and I had the correct version of Bluetooth and Android. We had several email exchanges during which they sent me the instructions (which I already had) and culminated with a step by step guide of how to reprogramme the lock using an app not available on Android. I asked them to send me a replacement but after 4 weeks I'm not holding my breath. Complete waste of money.

Awful, battery was flat when it came, the thing isn't rechargeable, it takes a cr2032 which is impossible to get to without a pair of mole grips which would damage the casingAvoid..
