Vauxhall Insignia insignia boot wont lock with central locking

Was it working o.k previously ? Does it unlock

i dont know how long it has not been working , i only noticed the other day
I lock the car with the remote , and all doors lock and the petrol cap locks , but not the boot it is unlocked all the time

Could try locking from button inside and see if it locks the boot and maybe resets the system

I have went in the car and locked it from inside, my wife still managed to open the boot.
I have no button in the car for the boot only the key fob and as i said the door button that i locked the car with.

Need to test for power at switch / lock and probably replace lock

hi the reason the boot wont lock is you have key beside car its a thing on insignias that if you come near car with fob in your pocket boot opens so you dont have to look for keys if you lock car and leave key in house and go back out car will be locked
