My Weiser Lock won't completely turn the lock

You didn't say much about the lock's symptoms beyond it worked great, then stopped. Here is the link to the troubleshooting instructions. The Weiser brand and Kwikset brand Powerbolt are identical (Black & Decker), so these instructions will work just fine for you:

A note about PDF files: If you cannot view a given file, you need to first install Adobe Reader. You can get the free download here:

Weiser has a one year warranty against electronic malfunction and a lifetime warranty against mechanical and finish problems.
You can review it and contact them for further assistance from this link:

Since you've had your lock "working great for a long time", I'll assume that it's probably an electronic problem, out of warranty, and Weiser will want you to order a replacement power board at a considerable cost. You can try leveraging them with Dissatisfied Customer outrage, and maybe they'll send you the part for free.Then, it'll work great for a long time, and you will be back in this same boat again.
After more than a year on this website, I've seen far more Powerbolt problems than any other, which leads me to my opinion that it is not very reliable, to say the least. After contacting Customer Service, if they won't replace your part for free, you may wish to consider cutting your loss and installing another brand of lock. Again, it's only my opinion that you consider a Schlage lock instead.
Good luck!

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:

http://www.weiserlock.com/Support/Faq/50160000000HhhZAAS.aspx

Or, alternately, this page for the Kwikset version, which is identical, if you have trouble loading the first page:

http://www.kwikset.com/Customer-Support/Product-FAQs/Faq/50160000000HhhEAAS.aspx

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!

This is the relevant excerpt from the troubleshooting instructions:
Why is my Powerbolt 1000 unit beeping?
To determine why your lock is beeping abnormally, please follow these steps:

1. Take out batteries and unplug powerstrip.
2. Let it sit for 1 minute, then put the batteries back in and wait another minute.
3. If it does not beep, the keypad needs to be replaced (17733-1).
4. If the unit continues to beep, the powerboard needs to be replaced (A17734-3,3 Powerboard 1470 brass finish; A17734-3,26D Powerboard 1470 satin chrome finish; A17734-3,5 Powerboard 1470 antique brass finish).

Since you've already gone through the battery change, this suggests that you need to replace the appropriate Powerboard for your lock.
So this is the link to Weiser Customer Support Page:

http://www.weiserlock.com/en/CustomerService/ProductSupport/SupportContact.aspx

I suggest calling the appropriate toll-free number and having a conversation with a representative about this problem, first of all to confirm that you need the part before you go through the expense. Secondly, your lock may be new enough for you to talk them into warrantying it, and thirdly, they will be able to get the correct part on order for you.

I hoe this has been helpful. Good luck!

I understand that you've already checked for any mechanical binding within the lock and between the lock and the strike plate--(does this problem occur when the lock is cycled when the door is open?)

I'm including a link to the troubleshooting page for your powerbolt:

http://www.weiserlock.com/Support/Faq/50160000000HhhZAAS.aspx

If you don't find a solution here, although the lock is beyond its one year warranty, I'd still contact Weiser Customer Service (preferably by phone) and appeal to them to help you troubleshoot or replace your lock. Here's the contact information:

http://www.weiserlock.com/en/CustomerService/ProductSupport/SupportContact.aspx

Good luck!

Let me assume that you've already installed the Powerbolt 1000 (the one that matches the picture!), so let me link you to the Troubleshooting instructions, which illustrates how to open and reprogram the lock:

http://www.weiserlock.com/Support/Faq/50160000000HhhZAAS.aspx

Please install fresh batteries at this time.

Also please take a look at this link,

http://www.weiserlock.com/Support/Faq/50160000000HhmZAAS.aspx

which tells you how to locate and change the jumper to set the lock up for a door which is "right-handed" or "left handed"-in other words, what side the door hinges are on as you face it from the exterior. If the jumper is set wrong, the lock will not function properly.

Lastly, here's a link to the Weiser cutomer Support contact page:

Good luck!

Hi... You have too be sure that the deadbolt is free when it go inside the deadbolt hole... however this system is very low power and the (over torque clutch) will sleep if the deadbolt it's not completely free.
Also if you try to open the door before you unlock it, you may block the the deadbolt inside the deadbolt hole. Take care too unlock the door before open-it...

Good lock or good unlock

The deadbolt may very free inside the deadbolt hole... This system is low torque and a over torque clutch may slip if the dead bolt it's not completely free inside the deadbolt hole... Also, if you try to open the door before to unlock it, you may block the deadbolt... take care to unlock the door before open it. to be sure that the dead lock is ok, you can turn the manual knob and be sure is turning very very easily.

Also are you no that POWERBOLT is a 3 codes memory? go to that link to see more info about that : http://www.fixya.com/support/t8006865-not_overwrite_old_codes_just_keeps

if the batteries are new and good, sounds like a problem with the lock motor..is it a new unit? if so exchange it. try another set of batteries.
