Boot Lid Opening by Itself

[angryengineer]

The boot lid of my 2005 Corolla 1.4 D4D saloon opens by itself every now and then.

A typical scenario would involve me going out to the car in the morning and seeing that the boot lid is wide open.

The car has remote central locking, and I lock it without fail when I leave the car.

What would be the likely cause here?

Interesting one ?  on the hatchback, if you unlock it by the remote it should still need to be manually opened by pressing the latch ,  is the saloon boot lid any different in operation or do you have some direct cable release like the petrol cap cover?

Someone nearby with a different car that could be operating yours  or someone playing a joke on you ?

Wonder why the alarm has not gone off , was the drivers door unlocked as well or did you have to operate the remote to open it ?
