Hi Shimmy
Sounds as if mine had a different problem from yours, so I don’t know if this will be much use to you.
Mine was loose and floppy and didn’t close flush. The fag lighter part wasn’t attached and didn’t work electrically, and the light didn’t come on when the ashtray was opened. This is what I did:
Push on the little indentation in the centre of the cover and let the ashtray spring open. (Sounds like even that part doesn’t work for you.) Remove the ashtray insert as if you were emptying it by pulling the small catch to the right and lifting the insert out – see page 76 (the 78th page in the PDF) of the Owner’s Manual here

Look behind the ashtray (use a torch) and undo the single Phillips number 1 screw that you will see right in the middle. The two screws that are easier to see (one at each side) are nothing to do with the ashtray. The entire assembly them slides out easily. Pictures of this are here:

It turns out that the only problem with the electrics was that the connector on the back of the ashtray hadn’t been properly aligned with its other half on the car. This meant there was no electrical connection, and that the assembly wasn’t seated correctly hence was flapping around loose. A little care with lining things up and the single fixing screw could be tightened fully home, allowing everything to work OK.
The latch mechanism is a bit of flimsy plastic like you would find in a ballpoint pen. I guess if this is broken, you would be best off picking up a complete ashtray from a scrappy.
Hope this helps.
