I snapped the hab door key opening a bottle of injector cleaner (I know !) Emailed https://www.replacementkeys.co.uk/?utm_source=review_request&utm_medium=email&utm_campaign=signature these people on Saturday afternoon with the details and key number. They mailed me back first thing Monday morning saying they couldn't do it from the info I supplied, and could I send them a photograph ? I took a pic of our spare key and the replacement landed on my mat Wednesday morning and was a perfect match, very happy with their service and all for just £4.95 !
