VW Bora 2000 - central locking problem - manni1167

Hi,

I have a problem with my central locking on a VW Bora on a Y plate (2000). The key no longer works the central locking mechanism from the driver side door. The key turns but does not engage the locking mechanisms (I do not have a remote or a fob) Currently the only way that I can get into the vehicle is by operating the central locking from the boot, the passenger side door works but this only opens/closes the passenger side door.

What can I do to rectify the problem?

Thanks
