BRK/First Alert SC9120B smoke and carbon monoxide alarm and 7010B photoelectric smoke alarm review

So I went to Lowe’s to get a battery for my remote for my remote controlled lights and I had birthday money left so I decided to get these two smoke alarms. I was going to get a 9120B but I couldn’t find one. I’m not sure if they even sell them anymore at Lowe’s since first alert just came out with new technology featuring new smoke alarms such as the SMI-100AC and SMI-105AC. Still these two alarms I got are decent.

what is the hack to unlock battery door?

[@elevatorswithESH]

Which model are you specifically referring to? There are multiple smoke alarms in this video

[@albertmcchan]

At 1:00, you mentioned a hack to unlock "SMI 105 AC" battery door.

@@albertmcchan for that one I just broke the lock by pulling really hard on the battery door

[@albertmcchan]

I just bought new BRK 7010 LBL with 10 year battery on EBay. Even though manual say 10 year factory locked battery backup, door is not locked.
