Even if a key was available from a member, it has to be programmed to your car.... You never really wanna lose all the keys to a Crossfire. Worst case, the entire security system needs replacing. Best case, a new key can be ordered ($100-150) programmed (another fee) with VIN, the car on-site, and a dealer that won't completely rip you off for the service like the dude that took your cellphone/keys.
