How Long Do Batteries Last In A Kwikset Lock?

Batteries are a necessary component of any device. Several factors influence the lifespan of batteries in a Kwikset door lock, including how frequently the door lock is used, the type and brand of batteries used, and the climate. The more frequently you use your door lock, the faster the batteries will deplete. Because cold weather drains batteries faster than hot weather, your door lock batteries will last less time if you live in a cold climate.

If the door is properly aligned, the typical battery life in a Kwikset lock is about 10-12 months, based on ten entries per day. The estimated duration is based on the fact that the lock does not encounter interference when locking or unlocking the door.

The Kwikset Smart Lock will notify you via the status light when the batteries are low. If you observe that the LED light on the interior side of your Kwikset smart lock begins to blink red, it is time for you to replace the batteries of your lock. The keypad flashing red light is another indicator of a low battery in the Kwikset lock. It usually lasts a week before the battery dies completely.

If you use the Kwikset smart lock app, you will also receive low battery notifications through it.

In case you were unable to pay attention to the low battery warnings and your Kwikset lock batteries drain completely, the lock will remain in its last active state, which means that you will no longer be able to lock, unlock, or program your lock using the code.

Pick Your Kwikset Lock To Open It In Emergency Situations

The most well-known method for unlocking a lock without the original key is lock-picking.  However, the procedure may end up damaging your lock or a few parts of it. Hence, I suggest using the procedure only in emergency situations as a last resort. Normally, a lock-picking kit is required for this method. However, a few paper clips will suffice. 

Here’s how to open a Kwikset lock without a key by picking it.

  • Step 1: Place the tension wrench in the lock on the side opposite from where the key’s teeth would typically rest.
  • Step 2: Place the rake into the lock where the teeth of the keys would go while maintaining tension on the tension wrench. 
  • Step 3: Twist the rake, pushing and pulling it out of the lock while being guided by sensation. The key pin should feel like it has reached the shear line.
  • Step 4: Turn the tension wrench in the right direction, and the lock should automatically unlock.

In case you are unable to pick the lock using a lock picking tool and are in urgent need to unlock the lock, you may take a locksmith’s help to open the lock using a drilling tool.
