I had a call last night from a lady who had lost her keys for her apartment in Wilmslow. She spent over three hours re-tracing her route around Wilmslow, unable to find them. Wilmslow Police station were unable to help.
Following call to me, and within 10 mins I was on site. It turns out the ERA B.S Lock was quite faulty anyway! also, the new lock ( a Union B.S. 3621 2007) was of the current standard, unlike the old ERA!
