A trapped key interlock system is disclosed. A pair of hollow tubular casings located one inside the other and each having a series of elongate slots are used. When the lock is in a locked condition the elongate slots are aligned as inner and outer pairs with engaging members extending through the pairs of slots is preventing rotational movement of the tubular casings relative to each other. The engaging members are biased towards this locked condition. On insertion of the correctly coded key the engaging members are caused to move against the biasing force out of engagement with the slots in the outer tubular casing thereby allowing the inner tubular casing to rotate relative to the outer tubular casing and moving the lock to an unlocked condition.

The present invention relates to a self-locking pushbutton for unlocking of a lock for a vehicle door, hood, covering or hatch, in particular of an agricultural vehicle, e.g. of a tractor, or of a construction machine.

A lock operating device (100) configured to be retrofitted on an electromechanical lock (200) having a key-receiving portion (210) is provided. The lock operating device (100) comprises a maneuver knob (110) and a key blade (120) being operably connected to the maneuver knob (110) and being insertable in said key-receiving portion (210) of the electromechanical lock (200), and circuitry (130) which includes wireless communication means (132) arranged to wirelessly receive authentication information, and which circuitry (130) is arranged to communicate the received authentication information to the electromechanical lock (200) via the inserted key blade (120). The lock operating device (100) thereby allows conversion of the electromechanical lock (200) from a first operating mode, in which the electromechanical lock (200) can be operated by a programmable physical key receivable in said key-receiving portion (210), to a second operating mode in which the electromechanical lock (200) is arranged to receive said authentication information wirelessly and be operated by the maneuver knob (110).

An apparatus for avoiding abandoning an infant in a vehicle, the apparatus including: a mechanism, for providing a first state of avoiding removal of the key from a vehicle's lock, and a second state of allowing removal of the key; and a control, for controlling the mechanism to one of the states of the mechanism as a function of presence of an infant in the vehicle, thereby avoiding the key's removal as a function of the presence of the infant.

A key management program causes the computer to operate as a position information acquisition unit, a key use condition acquisition unit, and a lock releasing processor. The key use condition acquisition unit acquires key use conditions including a lock releasing time and identification information, and key use location. The lock releasing processor transmits lock releasing signal to release locked state to key management device, if current time is within a range of lock releasing time and identification information included in key use conditions also matches identification information of communicating key management device, and position information acquired is a location preset as key use location.
