This post is to help those poor souls who need to change the numbers of their Chubb safe and have lost their Chubb safe changing instructions. Even though we are in Brisbane I am keen to help if your stuck, first you will need to make sure you have a “change key” which looks very like an allen key. If you have multiple safes be careful you dont mix the keys up as if you have a 4 number spin combination and use a 3 number change key it can cause you some frustration.
Today I am only talking about Chubb safes that have a “vault lock” see the picture below. Its worth noting that a 4 number combination has 4 changable numbers and as well as the last number that is at the end of the ” stop” when you get to the end of the dialing sequence.
I also recommend doing the changing process at the start of the day, that way if it all goes “funky” and you “scramble the numbers” you will have enough time to get some professional help. Almost every safe dial has 2 “indexes” which are the marks that the numbers line up to. The top (twelve o’clock ) mark is the one that is use to open the safe the other (11 o’clock ) mark is ONLY used when you are changing the numbers.
I have been in the safe industry for near 37 years and I have learned a very helpful tip. I get a piece if “blutac” and place it over which ever mark I am NOT using. So when I am changing a safe combination I will cover up the 12 o’clock mark so I don’t accidentally set my new number to the wrong mark. When I have finished setting the numbers I simply swap the blutac to the 11 o’clock mark.
Of course spin combinations are now very antiquated compared to a modern digital and I have heard all the arguments why mechanical is better than electronics and I am TOTALLY unswayed.
Chubb safes don’t normally put model numbers on the outside of safes because that could help Crims identify the strength of the safe if unsure of the model you have email a picture to me.
