Help, drivers door wont open.

[Mathew_ZS]

Evening guys, not ZS related but still within the MG family..

My dad's MGF drivers door will not open for some reason, The door lock pins inside the car both pop up but almost immediately go back down, we are having to get the passenger door open before it re-locks itself to climb through as the drivers door wont open with the lock pin up or down or even with the key.

unusual that we can still manage to get in through the passenger but the drivers door isn't having any of it.

This all happened after my dad 'deadlocked' the car one evening.

Any suggestions or possible causes? any help would be much appreciated.

Thanks, Mathew.
