I lost my key for my protector fire safe. No on lock is 71422
Go to the store where you bought the safe. Or contact the company that made it; if you can prove that it's your safe, they should be able to provide new keys, since you have the number.
Take it to a local locksmith so they can unlock it... They will charge you money for it but not that much.
Just pick it
If yours, you can bring to your local fire department to open.
