What is the deck lid?

NASCAR term for the top of the trunk.

(It's actually an '09!)

Leaky,

Driving my daughter's Civic today but I'm fairly certain that the center "button" pulls out to remove the fastener. If not, the center section pushs in. I've had mine out but don't remember which way I had to go.

If that fails, pull the liner and bust them off:

Item: Trunk lid, Interior trim, Trunk lid trim, Clip, Us built

The outer ring has prongs that are expanded by a finger that is attached to the middle piece. To remove, just pull on the middle piece using fingernails or very thin tools like table knives. It doesn't take much force, so I do it with fingernails.

Be careful to keep track of them all. They can be reused, and they cost more than it seems like they should.

To put them back in, pull the middle piece out about 3/8 inch, until the prongs on the outer sleeve will fit through the hole again. Pushing the middle in expands the prongs to hold it in.

Check a local autoparts store like "Advance Auto Parts" or "AutoZone". I purchased a tool from one of these stores(for about $5 or $6) to remove the plastic fasteners without damaging them. I used this tool several times on another car with similar fasteners on the trunk lid. It worked fine.
