Steering Column Repair: key wont turn., channel lock pliers, chevy blazer

Question
The key in my '95 chevy blazer will not turn in the ignition. What do i need to do to fix it?

Answer
Hi Michael:
Sorry about your truck.
When the lock fails, it's usually because it's not reading the key correctly.  Obviously, try another key first.  If that doesn't work, try spraying some WD40 inside the lock, not a lot, just enough to lubricate the tumblers.  Then, gently (as if your thumb were in the way), tap the key with a hammer driving it deeper in the lock while you attempt to turn it.  Do this repeatedly in fast succession...tap, tap, tap, tap, tap, all the while trying to turn the lock and key.

Finally, it none of that works, you are going to have to replace the lock.  The only problem is the release pin to get the lock out is only accessible in the 'start' position, so we will need to force the lock to get to that position, which means damaging the plastic lock cover and forcing it to turn with a pair of channel lock pliers.  Do this after you have exhausted all attempts to get it to turn without force.  Also, you will need to disconnect the battery, or the starter will remain engaged during this process (not good!!)

I am enclosing a link to our company website to help you understand the lock replacement procedure...it's fairly detailed and you need to be cautious or you will cause other GREAT expense by breaking the 4 way switch inadvertently.
