Mk4 golf Rear passenger door won't unlock

[JadeL]

I have a Mk4 golf, my rear passenger door won't unlock and I can't open it from the inside or outside... How can I unlock the door to be able to open it please????
I have to unlock my car, from the passenger side using my key in the door.
It was working till Saturday worked fine earlier in the day and stopped working I had to get my child out through the other back door. I don't think the child lock is on as pretty sure I've opened it from the inside before. But may be wrong. Also when pulling inside handle the lock button that pops up when unlocked dosent move when pulling inside handle.
I don't have the money to pay to get it fixed right now.

How areyou with DIY, etc? A typical fix will involve getting the door open, having the tools an confidence to remove door panels, and fit a replacement lock mechanism. You can chance a lock from eBay for about £20, but may also need £50 or so of socket sets, spline and Torx bits, etc if you don't already have them.

You can try rattling and banging on the inside of the door while doing whatever usually unlocks all the doors it to see if that makes things work, but it will probably be a one off.
