SaferProducts.gov consumer incident report 20210924-6DDD9-2147360410. Severity: Injury, No First Aid or Medical Attention Received. Product: Kwikset 99380-001 (Kwikset 99380-001 Halo Wi-Fi Smart Lock Keyless Entry Electronic Keypad Deadbolt Mode 99380-001). Incident: My Kwikset 99380-001 Halo Wi-Fi Smart Lock Keyless Entry Electronic Keypad Deadbolt melted and burned the tips of two of my fingers on Sept 23, 2021. On the late evening of Sept 22, 2021 I was in the laundry room that has a door to the garage and I thought I smelled a faint smell of something odd, like a sort of burnt toast. I checked all around and could not find the smell and it went away. The following day the Kwikset door lock in this room alerted us that its battery was dead and needed replacing. Later on Sept 23, 2021 I removed the battery pack from the lock housing and replaced all three 1.5 volt AA batteries, then reinstalled the battery pack . I then went to verify the locks operation and the lock would illuminate but would not lock or unlock. Then I started to smell a strong smell of something burning and I could see smoke emanating from the just installed battery pack. I tried to remove the battery pack from the lock housing by lifting up on the plastic removal tab, as I had done previously, it is at this point I burnt my finger tips on the molten plastic. I then went to the garage and got a dental pick to pull the battery pack out. Once the battery pack was removed the battery pack stopped melting and smoking. My fingers were sore but OK, no lasting damage. I then notified Kwikset about what just happened and uploaded pictures to them using their online tool. I asked Kwikset if there were any recalls on this product and they said no and there were no know issues. They issued me a case number and said they wanted the complete assembly returned to them for analysi
