  • Mechanical locking mechanisms in particular mechanical locking mechanism such as the European cylinder door lock mechanisms, exist wherein the cylinder has to turn multiple times, e.g. over 960 degrees, before the lock is unlocked.
  • fully unlocking the lock may take considerable time after the user has pressed the button of the transponder.
  • the user may experience an undesirable waiting time before he can actually open a door. This waiting time may even get worse as a result of some conflicting requirements of an electronic lock.
  • an electric motor of a lock is preferably small. Small motors namely tend to be more energy efficient, which is important because frequent change of batteries is undesired. In addition, small motors can be elegantly integrated with existing locks and can be conveniently mounted on doors. On the other hand, an electric motor must be able to deliver a certain threshold force or torque in order to drive the mechanical lock mechanism, which may include a cylinder of a cylinder lock. In principle, larger electric motors are able to deliver higher forces.
  • gearing enables to amplify an input force or torque delivered by the electric motor to the gearing system.
  • the amplified output torque may then be sufficient to drive the mechanical parts of the lock.
  • a small electric motor can indeed cause a force or torque of sufficient magnitude for driving mechanical parts of the lock.

  • the module, method and controller disclosed herein enable improved keyless entry systems that at least reduce the waiting time for a user that intends to unlock a lock, for example a lock on a door of the user's home.
  • the module is configured to unlock the lock in two phases.
  • the first phase is initiated by the controller in response to determining that an electronic key, and presumably a person holding the key, is within a predetermined distance of the lock.
  • an appropriately chosen distance allows the controller to already initiate the first phase while the user is approaching and has not yet reached the lock.
  • the lock will have already partially unlocked when the user arrives at the lock.
  • the controller will initiate the second phase and further unlock, e.g. completely unlock so that the user can access a house, locker, etc.
  • the second phase may only start once a user has interacted with the lock, for example touching the lock, therefore the risk of unintentionally completely unlocking the lock is avoided.
  • the electronic key may be associated with the lock and/or may comprise a smartphone or any other portable device that can transmit wireless signals.
  • the controller may be configured to control the transceiver module to transmit and receive messages from the key.

  • the direction of said respective rotations in the first and second phase may be the same. Also, the second angular distance may be smaller than the first angular distance.
  • the mechanical locking mechanism comprises a dead bolt and a latch bolt.
  • the controller is configured for, and/or the method comprises, retracting the deadbolt in the first phase and retracting the latch bolt in the second phase.
  • the user interface comprises a touch sensitive surface and the interaction comprises the user touching the touch sensitive surface.
  • the touch surface may be, when the module is mounted on the lock for controlling the lock, at the outside of the door.

  • the controller may be configured to repeatedly measure the quality of the connection, for example by measuring a power of the signal as received, such as an RSSI (Received Signal Strength Indicator).
  • the key may be configured to determine the quality of the connection, for example by measuring a power of a further signal as received by the key, wherein the further signal is transmitted by the transceiver module to the key.
