How to Determine Your Meter Lock Type

The best way to figure out what you need is to look closely at the lock itself. Take a clear photo of the face of the lock. Look for any stamped numbers, letters, or manufacturer logos on the metal housing. These marks are often the key to finding the right match.

If you cannot find any markings, you should call your local utility company. The service department handles thousands of meter boxes and knows exactly what type of hardware they have installed on their equipment. They can tell you the specific class of key needed for your area. If you are a professional electrician, contact your equipment supplier. They usually have a catalog of barrel locks and can help you identify the correct key based on the utility provider's standards.
