Nissan tech in Houston

I am in need of a tech to help me trouble shoot why my car will not let me register 2 new keys. I already took it to the stealership and they told me that the steering lock was not releasing. The car is a 2007 Versa with the intelligent key and was involved in a front side collision that deployed the driver's side airbag. Let me know if you can help out trouble shoot this issue.
