99 Disco I, driver's side front door won't unlock with remote. Replaced the actuator but didn't help. It just won't unlock all the way. Looked in there really close with a mirror and saw a small metal ring hanging loose. Now I remember reading one of the posts here, saying making sure it's not a broken ring spring before ordering the actuator. I just searched for an hour but couldn't find that post. Please help. I couldn't tell how to get to the ring/spring and how to fix it. Also, would a lot of lube help? Many thanks in advance.

 

I would try lubing it first.
If that does not help it is probably a broken spring.

 

I am pretty sure it's the spring. How hard is it to replace it? Do I need to remove the entire lock assembly from the door?
