Now the only problem is that it only has 1 ignition key!!!! Is there a definitive Mazda5 key thread i can refer to about getting duplicates?

Same as the 3. You can have up to eight keys and three remotes. In order to program new keys yourself you need two working keys, in order to program remotes you need one key. Since the car only has one key the dealer will need to plug into the computer, clear the existing codes, and program back in the new ones. The cost varies by dealer, but most pay somewhere around $50-75 for the programming as it apparently takes 45 minutes to do. As for the key you can get a regular transponder key from the dealer for $20-30, or an aftermarket transponder key for about $9. You don't have to get a flip key/remote. If you do get additional keys then I recommend getting two more so you have a total of three. That way should you lose one of the three keys you won't have to go back to the dealer to program in more, you can just replace the key and do it yourself. And if you're just getting more keys so that you have spares then I'd just go with the standard keys as they're way cheaper.
