Ok so last night my cel came on solid. So this morning i went to my girls parents house and got her dads code reader. Well all it keep doing when i was trying to get the code was saying err. I tried taking the key out waiting for a bit and trying again but still with no luck. any ideas or help>?

attach device, put key in turn to accessory, hid read on device, depending on device follow sequence to clear the code, sometimes you hold the erase button, it's ask if you want to erase? hit erase/yes, should clear em if it follows the same pattern as the autozone device. lol
