We will provide you with either a combination or a SUPRA electronic lockbox. Both are secure, however a SUPRA lockbox provides an added measure of protection in that only agents who have a supra keypad can get the key out of lockbox. SUPRA keypads must be updated on a regular basis and require a PIN to use. When the agent uses their keypad to retrieve your key, the box records their name and the time they showed your home, thus providing a log of the agents coming and going from your home. This is an extra measure of security to protect your home and its contents. A traditional combination lockbox does not provide this extra security, but can be useful for allowing non-Realtors� access to your home. Some clients opt for both types of boxes with the combination box in a secondary location. Realtors� are only allowed to use the SUPRA while service people are given the combination. This is at your option as a seller.
