I have a question for UK locksmiths. My flat in the UK changed the lock on the common area key. It is on a Yale blank that is also common here in the US where I am a locksmith. I have a photo of the new key, so want to try and decode it and originate a key before I fly back to the UK. I can of course pick one up at the managment office when I return but it is in a different town and will be complicated, at least on the first day back.
So my question is what are the depths and spaces used on the standard Yale rim lock cylinder that uses a JMA 1a key? If I could get the mm dimensions for spacing and depth I can easily sight read the key and originate one.
