The days of forgetting one's door keys might be numbered if your clients go for the Lockitron way-- replacing their keys and locks with the company's lock and smartphone app combination.

The Lockitron system uses a plug server and an ethernet cable connecting to an electronic lock. A server connects the lock itself, which opens when one uses the smartphone app from basically anywhere.

Clients using the system can also create multiple "keys" to email or text to friends and family.

The lock-replacement system works with both deadbolt and handle locks and is available in several finishes. Lockitron also offers a NFC-based option.

The basic Lockitron system involves a single payment (unlike similar systems such as Schlage's, which require a monthly subscription)-- with text message access available as a premium subscription-based service.
