Not mine but my stepdads, he has a 1999 zr7 and the steering lock has been used for the first time in 7 years. Unfortunately now it won't unlock. The key goes in and moves fine until the unlock point where it just will not unlock, we've tried wiggling the bars gently while twisting the key and sprayed wd40 in there to see if that would help and so far nothing, any advice would be greatly appreciated.
