Today I'm doing a video on how to change a flat (dead) battery on a Wertheim safe with a Sargent & Greenleaf Titan electronic safe lock.
If we punch in the code, which is 1-2-3-4-5-6, we get multiple beeping and the lock won't open.
So, the battery's housed under the keypad here. We pull this little blue tab forward and just slightly turn the dial ring anti-clockwise. The whole dial ring pops forward and then we see our batteries just behind them. So we take out the flat battery.
Then I just recommend using the Energizer nine-volt alkaline or the Duracell. So we plug in the new battery. Make sure the cable was pointing forwards and upwards from the safe. Pop it into the keypad. Pop the cable down and then just push the keypad dial ring forward.
So then we just test the lock and punch in our code and we get a single beep and a big loud click, and then our dial turns all the way around to the unlock position.
