I am close to the least "handy" person you will meet, but with some unhelpful locksmiths in my regional town, I figured I'd have a go at removing my old electronic lock & installing this new one!
Apart from one small mistake, where I didn't push the one cord you have to connect in hard enough, the whole process was straight forward and the instructions excellent! I installed the lock and handle easily, it's been working a treat & I can even enjoy opening the door with my phone if i want to.
