69 dart ignition lock cylinder

Had a Local locksmith drill out the old lock and replace it with a reproduction lock cylinder. Put it back together and now...

1) there doesn't seem to be a start or on position...only one turn to the right and one to the left.

2) Turn the key and I get nothing.

3) Idiot light comes on as soon as I connect the switch to the wiring harness as if it is already in the start position without a key.

Any thoughts? Is it possible to install the lock in the wrong position or is it a switch issue.

thx
