600 D/DF - Rekeyable double-bit locks

The 600D/DF rekeyable double-bit locks are part of the series 600 mechanical locks for armoured doors. Security is guaranteed even in the event of loss or theft: the owner can easily change the lock combination by themselves, restoring security without necessarily having to change the lock. This is an armoured door model, designed to ensure maximum protection, thanks also to the option of construction, service or master keys, which rekey the lock and cancel the previous key combinations up to three times.
