Hi, I'm having the same issue currently. Just to be sure, "when the lid is pressed down" do u mean the key fob button?
***  No, the car bonnet/back lid.

So have to open up the key fob and service it basically? tq

**  Dont understand this.

Yeah. I greased back the latch too. Seems to be working.

*** Good. The latch may get sticky again years later. But now you know how to fix that. Problem is when your family member is using the car, going shopping etc, and that happens. Then phone call to you. Ha.

They should design out this problem as others have experienced this too. However, My 12 years old Proton Wira did not have this problem. So depends on luck and usage?

I still think it's the keyfob. I haven't tried the spare fob yet.
Have you try holding down the lock/unlock button simultaneously until the fob light blip? any changes?
