I would like to get a lock for my meter box.Postcode 3105, Victoria Questions1. Any recommendations? 2. My electrician suggested Lockwood ASSA ABLOY 334B45 box was suggested. https://www.lockweb.com.au/en/lockwood-products/padlocks-and-outdoor-security/high-security-range-padlocks/high-security-334-series-brass-case-padlocks/ 3. Once the lock is installed, do I need to inform AGL? Does AGL have the universal keys to this one? Thank you.
