Hey folks,
I'm a fellow locksmith (of 20 years) and have had a request from a lawyer, acting on behalf of a property management company, to help explain at a tribunal hearing, why a lock in a high-rise apartment building would open with a random key. This hearing is due to a theft which allegedly occurred from a tenant's residence. I have examined some of the locks which were previously in-use on this building (thankfully we got the contract to replace almost 300 deadbolts after the alleged incident took place). During disassembly of some of the formerly-installed deadbolts, I found that many of the locks had been bastardized by whomever had worked on them over the past 10 to 15 years (estimated) from when the initial master-key system had been set-up and implemented. The specific lock involved in this case, had bottom pins installed as driver pins in the last three chambers and being a Weiser, it wasn't as tolerant as some other manufacturer's products are to having random keys work them. I have been searching the internet for some kind of visual aid, or explanation which is presented in terms which can be more easily understood by the laymen who will decide the outcome of this case. In my opinion, this landlord had no idea what was inside of these cylinders, and the fact that they sprang for new locks after this happened, said to me that they genuinely showed concern for their tenants. Any help would be greatly appreciated.
Thank you all and keep up the great work on this newsgroup!
