It happened to me but the car was parked outside my office at the time. So I assumed someone had tried to break into it.
As such I got it done on the insurance ( lucky as the glass alone was around the £350 mark !! ) but the fitters had a hell of a job releasing the locking catch from the glass ( interference fit - disimilar metals - bad engineering ). They destroyed the lock trying to prize it apart with a bearing puller.
If your guys have trouble finding a replacement new part the scenic lock is indentical. Apparently the dialogys software does not make it easy to find the part number on the laguna..
