Land Rover Repair: Lock Door stuck, grease, few days

Question
I own a LR Discovery 1 1998. Few days ago I realized that a front door was a little hard to open, I've heard that lock had to be lubricated or one day it was not going to open, so I removed the door interior cover and lubricated the point of mechanism I had access. I didn't move any
ajustement, only put some grease on points I was able to see. It worked perfect like a new one, but only one day, becasue now it's close and I
can not to open it again. I still don't understand what happened but I am very worried for opening it again. My question: Do you have any idea how I can open it? Thanks a lot!

Answer
Huh It's a hard to solve...
You have to disassemble the inner cover, and than check the rod's. Maybe some rod sticked. Or try to pull them one at time.
If you have luck It will open, otherwise you must imrovise.
In that case I have to improvise oftenly... I know It's not easy.
