Trunk key
The trunk release key on my '06 convertible suddenly won't go into the cylinder. Something is preventing the key from going more than 1/3 of the way in. I've sprayed WD40 into it but it hasn't helped yet! It was working fine in the past! Any suggestions? Where can I purchase a just a replacement cylinder or do I have to purchase cable and all?

Use a heavy rag or towel folded up underneath the lock to protect the paint and catch the outflow.
Use WD40 as a "flooding stream", continuous for seconds at a time to soften and force the debris out of the cylinder. May take awhile.

Have you tried wiggling the key and pushing a bit harder?
I test both keys once per year, the first one is usually rather difficult to insert and equally difficult to turn. One that's done, the other key goes in and turns much easier.

Ditto, with the amount of dust that get inside the rear bumper cover, not only can the lock get packed with debris, but the hatch switch button next to it as well.

I am a big fan of WD 40 and I use it all the time, but I read somewhere not to use WD 40 inside of locks. The residue left by the product is the cause for dirt and "gunk" build up because of the oily nature. The same article suggested using nothing but graphite in the lock and working with it that way.
