Try lifting the driver's door handle as you turn the key. If you've let the mechanism seize up through lack of maintenance, then you are now reaping the rewards.
You can't work the locking solenoids from the boot if the locking ECU is connected, because both relevant wires are earthed, and one of the deadlock wires doesn't come into the boot.
Only way in I can think of is to remove glass.

omg it worked managed to get it open thank you very much

I ve had this problem a bit recently, yeah lifting the door handle does seem to work
