I recently purchased a 2003 X Type car that came with 1 key, However I wanted to get a replacement key with remote. I went to the dealer Nielo Jauguar In Sacramento and was quoted $480.00 for the KEY, FOB, and Reprogramming.

Breakdown:
Key Cut $25.00
Reprogramming $240
Key Part and Remote $295

After the conversation I said I would think about it. I went online and after inquiring numerous places here is what I did:

I bought a Key and Remote (1 Unit) for $95.00 from Remotes.inc shipping was quick

eBay My World - remotes.inc


I then I called the list of approved Locksmiths and found that

Key Smart 91644403644 to have the best prices $99.00 out the door for the Cut and reprogramming

Final Price for peace of mind and a New Set of Key with Remote $295.00 half the price of the dealer.
