This is a SentriLock lockbox - they aren't seen often in the London area (we use Supra lockboxes here), but are the main type of lockbox used in places like Oxford County (Woodstock, Ingersoll, etc.)
With Supra lockboxes, an out of area Realtor needs to signup for lockbox access with our real estate board before being able to open one.
SentriLock lockboxes are a bit different - they allow out of area Realtors to open them, with some required conditions: 1) The agent must have the SentriConnect app installed on their phone and either 2) the listing agent supplies the showing agent with a one day code or 3) the showing agent has their email address added by the listing agent to the lockbox settings to allow them to open it during the scheduled showing time.
