SentriLock and SentriGuard Lock Boxes Previously connected to TenantTurner

I have 26 lockboxes that we used at a property management company that were all connected to Tenant Turner. All 26 boxes were tested and all in good working order. There is one box that is marked that opens, but displays an error code when closing. Otherwise all boxes work flawlessly. This auction is for all 26 boxes, there is no reserve and we will ship regardless of what auction closes at. I value this lot new at $6,500. I value this lot in current condition at $3,000. We have no need for these boxes and will sell at a discount.
