By the way you might want to read carefully the Needswings site if you have a UK spec car the price is $319.99 + shipping a lot more than I paid in £

Technical Specs
This is a brand new Switchblade Remote Key for the 2004-2008 Chrysler Crossfire. We will need your VIN number and exact miles when you check out so we can order it for you. It takes about 2 weeks to receive it. When it arrives it will work right out of the box - you won't need to do any programming.
Don't order if you haven't read these 3 important points:
You will need to email proof of ownership (scan a copy of your license and registration) to
help@remotesandkeys.com after you pay. Please include a picture of the dashboard of your car clearly showing the mileage in the email you send to
help@remotesandkeys.com.
Note: The shipping address details must match the person and address on documentation or we will not process the order. It is important for us to be sure we are sending a working remote key to the registered owner of the car. Example of what we don't want to see: Husband orders remote to be shipped to his name. Documentation shows wife is registered owner of car. Only the registered owner of the car should place the order. Shipping name and address must be that of the registered owner.
If you can't give us the exact mileage we can't process your order. In that case we'd suggest contacting your local Chrysler Dealer.
(Note: This is for Crossfire's built for the US market. If you have a Crossfire built for outside the US the price is $319.99 plus international shipping.)
