had same problem with mine, like hellcat said pull back seats down and remove plastic cover and open boot with the catch on the lock, it was because i had pushed the button in before the central locking had unlocked fully, there is a white plastic guide which moves up and down to unlock and lock the boot, it is connected to the motor by a bit of cast metal, if you push the white plastic bit up or down (cant remember which) and close boot it should work off the bootlid button and should work ok with the central locking as well then
