Veracruz No Start

Customer presented a 2007 Hyundai Veracruz, twist to start + proximity - and it wouldnt turn over the twist ignition or recognize the key, but the remote still worked. Proximity entry at the door did not. Immobilizer light on. 
Programmed a replacement key, ignition works - proximity works. The wound proximity coil on the original key failed, resulting in a no start. We cut a mechanical key for it as well. Thank you for your business.
