Just a bit to pick up on my previous statements concerning the shoddy quality of Weiser, Kwikset and similar low cost locksets.
I just tore apart a lockset that was given to me. There are no markings on the lockset, but it is an entry lock. It appears to be a Weiser Huntingon key in knob entry set.
After careful examination I discovered that when normally in use, both spring tabs holding the inner and outer knobs in place are exposed. Even when installed.
Using this spring tab, I removed the outer keyed knob, and had the lock cylinder fall into my hands. This is where it gets interesting. Since I always knew Weisers were a bit dodgy. Since I don't use them often, I had not seen this part until now.
The lock cylinder is made of plastic. Really cheap, flimsy plastic. The plug is brass of course, and Weiser is still continuing it's practice of tapering the driver pins and attaching the springs directly to the pins.
The spring retainer clip slides along two grooves in the cylinder body, and fits so loosely that I would expect it to pop off with very little pressure.
The latching mechanism is the expected cheap stamped Weiser parts. Nothing new there.
Basically, I reitterate my stance that most Weiser locks in use today in apartment buildings, and other locations are most likely to succumb to relatively minor force attacks. In addition, I would have to say that picking one of these is different because of the plastic cylinder. It creates a situation where a screwdriver might likely create enough turning force to open the lock.
I was shocked that Weiser quality seems to have gone down, not up. If you know anyone, including yourself with one of these locks on your home, apartment, business or anywhere replace it immediately. If you can't replace, augment the lock.
