Very common for the keypad to stop working.
check that the keypad is not defective. You can disconnect the batteries and then unplug the keypad. Now put the batteries in without the keypad connected. If the beeping stopped, your keypad may need replacing.
You can get a replacement at the store where you bought it for free or call the Weiser support line and they will mail you one for free.

Let's review the programming steps, in case you are overlooking something. This information was found at this link:

Important before proceeding: 1. Verify that position #2 of the "Settings
Switch" is in the OFF position. (Refer to section 11.) 2. Work with the
door open (away from jamb) to avoid accidental lock out. 3. Make sure
the bolt of latch is in the extended (locked) position

8. Automatic - Bolt Direction Determination (Door Handing).
IMPORTANT: DO NOT SKIP THE FOLLOWING STEP.
LOCK WILL NOT BE ABLE TO OPERATE PROPERLY!
? In the steps below, the SmartCode mechanism automatically determines the "door handing" and sets the proper direction for motor to rotate.

a. Press and hold the "LOCK" button on the exterior keypad, while fully inserting the battery pack into the interior assembly (the tabs on the pack must face out)

b. When the unit begins to operate the bolt, release the "LOCK" button.

c. Do not disturb the unit for approximately 20 seconds until the interior Green LED flashes followed by a beep. During this time the system will drive the bolt several times, will determine "door handing", store data in memory and exit. It is very important that this process is allowed to finish properly.

Proceed with programming your Usercodes per the instructions.

Finally, here is the contact number for Customer Service At Kwikset. Call them if you still have the problem.

"I have installed your Powerbolt, but when I push the Lock Button, it unlocks? What should I do?"
First remove the cover on the inside of the Powerbolt unit. On the right hand side under the batteries, you will notice that is says "Door Direction Jumper". If the cap is mounted on Prongs 1 & 2, carefully remove it and move it over so that it mounts Prongs 2 & 3. A is right handed, B is left handed.
These instructions will work just fine for you:

These locks are made to work on a door which, when you stand outside and face it, has its hinges on either the left-hand or right-hand side of the door (= door "handedness").
The jumper controls that for the appropriate installation. Yours is set wrong!
