you need a bypass which does passkey 3, since your current key has rf signal embedded inside of it.WesMan

The 07's use the same bypass module as the 06's and 05's. It's a RF type immobilizer that you will need to attach a ring to the outer edge of the key cylinder. Make sure that the wires that your using to wrap around the key cylinder is enough to transmit the signal to the OEM immobilizer ring. This is one of the most common problems with RF type systems where the remtoe starter powers everything up and then has a failed start/no crank.Jeff
