Car won't unlock

[berlina95]

I have left my car for about 5 days just sitting outside and when i went out there to move it before the doors are locked up and the boot won't unlock either
I have tried using the key buttons to unlock it and also tried manually opening it but the driver door and boot both seem locked up.
If anyone knows how i can fix this problem please help!
It is a 1995 VS berlina wagon
Thanks

Is the boot an electric type lock?

you might be able to open the bonnet from under the car or bumper by pulling on the lever where the cable ends then put another battery in because to me it sounds like your batterys gone flat its worth a try.
