In short, it is possible to make a key for opening a barrel lock, but it is probably not a very good idea. A barrel lock or cylinder lock is a delicate and precise lock that can be easily damaged by anything other than a genuine meter key type tool. To ensure the long term viability of a barrel lock it is important to use only an approved key or tool that is designed specifically for the lock you are attempting to open. There are a number of cases where people are selling devices that they claim will open a barrel lock online. You should avoid these devices and only use approved and genuine tools. Always buy from an approved source that will help you to match the exact key or tool to the barrel lock or cylinder lock you are working with at any particular time. BarrelLockMeterKey.com is your number one source for perfectly matched tools and keys.
