RNA also has been shown to be able to replicate without the need of specialised enzymes, though the process is not as efficient and is prone to errors (thus imposing a selective pressure to develop better means to replicate).
Your anaolgy of DNA as to that of lock and key is way out of scope. DNA has much more in common with human language and computer languages. Futhermore, DNA transcriptions is an encoding/decoding mechanism isomorphic with Claude Shannon's 1948 model: The sequence of base pairs is encoded to messenger RNA which is decoded into protiens. Doesn't sound much like Lock & Key to me. Information theory terms and ideas applied to DNA are not metaphorical, but in fact quite literal in every way. In other words, the Information theory argument for designis not based on analogy at all. It is direct application of mathematics to DNA, which by definition is a code.
I like to direct your attention to the following:
Direct comparison between communication systems in Electrical Engineering and the DNA communication system.

Above: Claude Shannon's communication model (From The Mathematical Theory of Communication, University of Illinois Press, 1998).

Above: Hubert Yockey's DNA communications channel model. Notice that it contains the exact same components as Shannon's. The two systems are isomorphic. My thesis complies with communications systems of this type are always without exception, products of design.

Thank you for your agreement. You're right Strata in rocks and Rings in wood are all Patterns and not Designs. They all have self encoding information and no decoding mechanism. DNA has both encoding/decoding. Designs are symbolic and only consciously intended, DNA is definately a design and not a pattern. Patterns come from chaos created by matter and energy. Requires no copies and requires no thought from anyone. With information you have to have Matter and Energy and Will. All information requires a thought process. Can patterns turn into design? Is there a natural process that allows that to happen?

In fact, Evolution is so much an effective deterministic system, that it is able to produce better designed traits and features than what humans can do themselves. Such simulated systems have been used outside of biology to help design more efficient aircraft and structures.
This is Shadow's area. I'll let him pick this one up.

It doesn't mean that the carbon is actually telling the other atom something, it just means that an electron wandered off.
Okay I see that one flew right over your head. Let's try it again.
Common dictionary definitions:
CODE: 3a: A system of symbols for communication 4: Genetic Code
(Webster's 9th collegiate dictionary)
GENETIC CODE: the biochemical instructions that translate the genetic information present as a linear sequence of nucleotide triplets in messenger RNA into the correct linear sequence of amino acids for the synthesis of a particular peptide chain or protein. Cf. codon, translation
(Random House Unabridged Dictionary)
DNA: A nucleic acid that carries the genetic information in the cell and is capable of self-replication and synthesis of RNA
(Houghton Mifflin Dictionary)
DNA: Genetics.
deoxyribonucleic acid: an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms, constructed of two nucleotide strands coiled around each other in a ladderlike arrangement with the sidepieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine and pyrimidine bases adenine, guanine, cytosine, and thymine: the genetic information of DNA is encoded in the sequence of the bases and is transcribed as the strands unwind and replicate. Cf. base pair, gene, genetic code, RNA. (Random House Unabridged Dictionary)

Read above. Common Dictionary Definitions:

Encoding in fact goes from the soup made of four bases to DNA. DNA is encoded with four interchangeable "building blocks", called bases, which can be abbreviated A, T, C, and G; each base pairs up with only one other base: A+T, T+A, C+G and G+C; that is, an "A" on one strand of double-stranded DNA will "mate" properly only with a "T" on the other, complementary strand. Replication is performed by splitting (unzipping) the double strand down the middle via relatively trivial chemical reactions, and recreating the "other half" of each new single strand by drowning each half in a soup made of the four bases.
I also refer you to read Yockey in the application of DNA's code for the growth of an organisim pg. 33-35 And Yockey acknowledges that the source of the original encoding is unknown, a question in which naturalistic theories cannot answer.

You just arbitrarily assign that label "code" to DNA so as to further your cause of ID.
Thanks for agreeing that Nature doesn't produce code and information. 
And as I mentioned in my previous post: The definition of code I have provided is sufficient and applies whether the code is arbitrary or not. You and Bluefinger sound more like you're arguing with me and not the opposite.

And your problem is this:
