Hello,

Could someone recommend a place to buy a replacement lock for the rear door of my doblo van, preferably online.

It refuses to open regardless of what I try. I've even had it in the garage who couldn't sort it.

As I'm not really clued up on mechanical issues, I thought I would seek some help before parting with my money.

Thanks.

Would have thought main dealer only. I had a quick look on ePER and have found a link for the up and over door whereas yours is probably the side hung doors. I'm not sure how current the price advice is with the ePER link from this forum but as a guide price not to damaging.
Have you had a look through other related post in the Doblo section, because the van rear door issues have been posted which may give similar symptoms which could give evidence to a different mechanism fault rather than the lock.
Here is the ePER link that I found just to give you an idea on price:

It is a main dealer only part unfortunately I have just had to get one from fiat as a little piece of plastic inside broke and they would only sell me the whole drivers door lock at a not so nice price of £90
