Gilly - thank you! Connected the old lock, and the key turns.

Swapped in the old lock - noisy (as before) but everything works!

Funny - my WIS doesn't say anything about reprogramming, but maybe my version of WIS is before the lock got superseded to a new number, and the new number requires the reprogramming.

Thank you again! I am SO glad not to be having my car towed to the dealer to fix a repair I bungled!
