Question:Anyone have any idea how to reset the code with the door shut or what
the code may default to on a Brinks home safe? I let the batteries go
dead. I'm not sure of the model, but the key has the number 3709 on
it. Could that be the model number ?
Answer:If you've installed fresh batteries, then the safe lock should come back to
life with the same combo that it had. These locks have a non volatile
memory. As far as the number on the key, that has nothing to do with the
safe lock or model number. That is simply a number that the manufacturer
would use or locksmith would use.
