Spare Keys and Remote(s)

[pikey]

Just wondering if anyone knew the cheapest way to get keys cut with "chip" for immobilizer in it. I rang Southside Ford in brisbane and they wnated to charge $200 for key and the immobilizer to have the code put into it! I thought this was harsh as i have seen it for around $70 at Mister Mint stores for Holden keys! Also they quoted me around $80 for the remote(s) for the doors and boot. Is this correct or is there a cheeper way to get these too. I don't want to spend much at all, but bought the car from a dealer who only had the spare key, so have been rooted by him, and looking for the cheapest option.

Help please!!!
