Need a spare key? Key Factory turns a photo into a finished duplicate.
Lay your key flat on any bank card, take a picture, and the app measures it. The card gives us the scale, so we can identify the key blank and read each cut to a fraction of a millimetre. We then cut your key in our UK workshop and post it to you, tracked.
HOW IT WORKS
• Scan — place the key on a bank card and follow the on-screen frame. Mortice keys take a second close-up of the bit.
• Verify — we match the blank and decode the cut depths. A person checks every order before anything is cut.
• Receive — your duplicate is cut in the UK and dispatched securely to your door.
WHAT WE CUT
• Cylinder keys: Yale-type, euro profile and most household door keys
• Mortice keys: 3, 5 and 7 lever, including ERA, Union, Chubb and Legge
• Security keys, on proof of ownership
BUILT FOR SECURITY
• Your photos are encrypted and used only to cut your key
• No address is ever stored with a key image
• Restricted and security keys need proof that you are entitled to a copy
• Ordering and payment happen on our secure website
• Your results now show the first two cuts of your key code.
• Each measured cut is marked with a red dot on your photo.
• Security keys are recognised and you are taken straight to our security key range.
• Reliability improvements.
