Hi Everyone,

I have just joined from Ireland. I’m hoping I might get some help to open my front passenger door which wont unlock, from the inside or outside or with the fob or interior button. Ive tried all of the tricks but no joy.

Now I’m contemplating having to cut the door card off. Has anyone else had this happen and found a solution. Obviously it would be a lot easier to remove panels if the door would unlock but im stumped on this one. The car is a 2013 i30. Thanks

I had this happen on the rear door of my 2011 FD, and whilst I was contemplating how to cut the door card off, it just decided to unlock one day, after weeks of not unlocking. I then took the opportunity to replace the lock mechanism. Even with the door card off, it's hard to see how it would help, because you still can't get to the deadlock mechanism. It's all enclosed in the lock case, which can't be extracted unless you undo the screws holding it in, which you can't get to with the door closed. The apertures in the door inner skin aren't big enough to get at the lock from the side. All I can suggest is keep trying to open it with the key fob, and you may get lucky. Whilst the door is open, remove the door card and unplug the electrical connector from the lock, that will at least disable the remote locking while you're trying to solve it.  On the FD, the door can then be locked and unlocked using the internal door handle but on the later GD I don't think that's possible.

On my car the sound coming from the lock as it locked/unlocked was noticeably different from the other locks. The deadlock has a little motor driving a leadscrew to isolate the lock latch from the flexible cable attached to the door handle. If the motor has worn brushes or the leadscrew gets stiff, it doesn't have enough oomph to unlock it. You should hear some noise from the lock, if you hear nothing there may a loose connection somewhere.

Just a thought for those with door lock problems.
What is the state of the car battery?
or have you tried unlocking whilst engine is running, to ensure voltage is enough to the troublesome door lock?

You could also try unlocking the door at the same as tapping the door with a mallet, to jar it loose. That's why I was wondering what sound was coming from the lock, whether it's completely dead, or struggling.

Try disconecting battery as I'm sure I read as part of safety feature they should all unlock when power removed.
