Hello,

Okay, so when you changed your ignition lock cylinder and keys they needed to be programmed to your vehicle's Power-train Control Module (PCM) or "computer". This can only be done at a locksmith or at the dealership. It is intentionally done this way to keep thieves from stealing vehicle's. Please get back to us with how everything turns out.

Thanks,
Alex
