This has probably been discussed before but it's new to me. I'm having issues with my 2 year old Liberty Safe. I've changed the Duracell battery a couple of times as instructed but all of a sudden it goes into 'penalty time' or lockdown mode even when the correct combination is punched into the Securam touch pad. I've sent a message to Liberty but not heard back yet. Being locked out of my safe causes anguish. I let it set overnight and it began working again.....but then a few hours later......locked out again. Wished I'd got a mechanical dial safe.
