A good emergency locksmith can make a key for any lock. They use a colored dye that shows where the tumblers hit. They file that off, and retry. If the dye shows the locksmith will file more until, finally-a key. Sometimes there is a code stamped into the lock, sometimes it has to be done by impressioning, but it can be done. The only consideration is that if it is an inexpensive padlock, it may be more cost effective to just buy another.
A locksmith generally has to have the lock cylinder in his possession to make a key for entry door locks. The "pickproof" brands such as Medico, Kaba, Multi-lock, etc. are even tougher and often involve proprietary key blanks that only the original seller can access. Certainly, no legitimate locksmith is going to make keys for a dwelling without seeing the customer's proof of ownership. Knowing the brand and keyway would help but you would still have to decode the lock in order to make a key to work it. If you are coming home and the door is not locked I would also check to see if there is a window or patio door that someone may be able to use to gain access as many people don't think of this when securing their homes and your visitors wouldn't be able to lock up after themselves when they leave due to the fact they don't have a key.
As you can tell, locksmiths are important all over the world and throughout history. They are an important breed of human in our society, and yet one of the most overlooked. Locksmith parramatta are constantly put to the test and should be famous for their endurance.
Being a locksmith can be a profitable, enjoyable business with many rewards as long as the proper precautions are taken. But the gratification the locksmith gets from the customers who truly appreciate the help and show it is sure to be worth the effort. No job is perfect, and there are probably as many drawbacks as there are happy memories. But as with any other job, there will be good days and bad days and plenty to relate to the children and grandchildren.
