or code 252308733540 Can anyone confirm my suspicions that although the cylinder might be genuine Yale, the lock body is lacking the logo on the internal lever? It's for a holiday let, with no connection to my address etc. I'm most concerned about the potential aggravation if people can't get in when they arrive if reliability is in question, and being able to swap the lock in years to come for the same.
