where do i get spare keys?

[KrisW]

I bought my truck back in December with 2 keys and an installed alarm from Toad. I always use the remote from the alarm to lock/unlock the truck and the key for ignition.
the problem is, what happens if the remote gives up the ghost? the thing is, none of the keys work on the locks.
is there any chance of getting a new key without having to change the whole lock?
thanks
