PLEASE DON'T USE GLUE!!!!!!!!
as a locksmith i've seen too many broken keys that have been superglued into the lock with no hope of removal.
if you take it to a locksmith the service will probably be < $20.00 but after its been glued into the lock, its a matter of getting a new ignition switch, rekeying to be the same as the rest of the locks, then (on some cars) dissassembling the dash, removing the old one, which could be glued into the housing (dependant on ho much glue you used) in that case there will be a lot more trouble involving getting the old one out before the new cyl. can be installed! my advice is:
go to a Locksmith in your area
