How much does it cost to change the locks on lock?

He wanted to know what is the average cost of a test bolt heavy duty blow. A single lock. I can multiply I always have to change all the locks on the house. In addition, if you have any recommendations for which the brand is the best passer. I have some and online research, I would like to hear your thoughts, experiences or advice. Thank you.

I've done my research and also Medeco and Schlage Primus. And to summarize it here for you is … Primus offers a higher level of security against shocks, but Medeco is more secure against picking. So I suggest to get each one for highest level of security Primus lock key is hit and collect proof resistant Medeco is more difficult to collect and very resistant Medeco key stroke will cost about $ 140 for a single cylinder Schlage Primus also about 140 for a single cylinder, but I saw it in www.armstronglock.com for $ 115 and there is a comment I found interesting "I saw an article on the main shock Digg a few weeks ago that linked to a video on youtube that shows how easy it is to hit. I have nothing of value, but the concern that most of the owners / renters insurance does not cover theft if there are no signs of forced entry. Well long story short, I seemed to find a local locksmith to me convinced that, although may be excessive Schlage Primus, Schlage Everest cylinders, while much less expensive than Primus will give me pretty good shock protection key. Everest has a sidecut that property type "help" key impact protection. The reason given is that the blanks are Everest difficult to obtain than 90% of the cylinder door. Unlike Primus, which are very strictly controlled in the lock industry. If you receive a Primus locks, the sidecuts are unique and specific to the purchase locks, which means that it is captive to the locksmith. Primus keys also have a weakness breaking due to the regular cut key in combination with the sidecut. There are other low-hanging fruit, by someone who wishes to gain easy entry to a house / apt. Most 999 sets of keys are for the most common (Schlage, Westlock, Weiser, Yale kwickset and low-quality cylinder pin 5). Home security is mostly about Detering and make it difficult for a would-be thieves and, in turn slowing them down. my 2 cents "
