citroen xsara boot lock broken

[mk3gti]

hi people, ive been having a problem with my citroen recently, basically the key cannot unlock my boot and the only way i can get into it is by pulling down the back seats and climbing in. im wondering if anybody know if there is a way of opening the boot from the inside, ive had a quick look and it looks like i can get the inside pannel of. any help would be great. thanks again
