Today i went to start the truck and something in the ignition popped and now

then it doesnt do anything. How hard is it to replace.

1 Answer


it shouldn't be that hard , generally you would disconnect batt. turn key to run and there should be a pin under the column(or somewhere) that you depress and the cylinder comes out , it works like a rack and pinion , if you look in the cavity you'll see the rack that operates the switch and the cam on the lock have to match up , it's all in the detail , a pro lock smith can save you some $$ instead of the dealer , check you tube for any videos
