That average  person who gets 8 hrs sleep and is firing on all 8 cylinders for 16 hrs will kick your ***, every time.....

For *most* Americans, a small 4 cylinder economy car of good mechanical quality makes the most financial sense.

I change lock sets between tenants (landlord locks - a couple minutes per cylinder).  

When Henry Ford told his engineers it was impossible to make an 8 cylinder engine he told them to make it.  

In addition, I had someone pop the cylinders out of them a few weeks back at one of my buildings in Berwyn.... frustrating!

The likelihood is that you have performed poorly compared to someone in the same situation that ran their business professionally.I hope the cylinder you are playing Russian Roulette with has many more chances.

Doorknob without cylinder has less things to break. 

Literally every other house has a giant plastic cylinder in their front yard. 

I haven't seen it but will try to go by on my next trip (maybe this weekend) and/or get pictures and confirm manufacturers/etc...On our ranch we have a large uncovered concrete cylinder that we pump into for the animals.

Here are pictures of the internals of the KwikSet Smart Key, you can see the majority of the cylinder is plastic:http://www.lockwiki.com/index.php/Kwikset_Smart_Ke...That being said, if you really are looking for a lock that is harder to force entry on, look at Schlage Primus, or other similar keys that actually have two sets of pins.
