Deadbolt barely moves in weiser lock
I assume that you get the same results whether you operate the lock with the door open or the door closed. That is, that you've already ruled out a bind between the closed door and the door jamb.
I'd recommend changing the battery first of all. At this time of year, cold weather can have a negative effect on your battery power.
If you've already changed the battery and are still having the problem, you should pursue having the lock covered under warranty. Weiser has a lifetime warranty covering the mechanical operation (and finish) of their locks. Before they cover it under warranty, they are going to ask you the same questions about battery and binding that I've already mentioned.
To change the battery for your lock, go to this web page:
Or, alternately, this page for the Kwikset version, which is identical, if you have trouble loading the first page:
Notice that the above are of the " .PDF" file type. That means that you need to have Adobe Reader or similar installed on your computer to view it. So if you are unable to view the file, download (for free) and install Adobe Reader first. You can get it here:
Finally, the warranty information link:
Review it, and then follow the "Support Contact" link on that page. It's always best to contact them by phone and seek their assistance.
Good luck--and please provide feedback if this helps!
