2008 Cadillac door lock II

So after ranting about the incredibly complex door mechanism, here is another solution. The driver door comes with an emergency manual key. Of course it is a dealer item and has a custom clasp to attach to the key fob. It would be easy to use the key if it worked on a regular key ring. So Lowe's giant hardware was able to put the key in their key machine and it said to use a #28 key blank, which they don't carry. With this information it was time for a trip to Ace hardware. They put the key in their key machine and it said "no information on key". So the key person dug through their blanks and found #28 ! They tried it And the machine cut the key. The key works ! $4, rather than $1000. So half the time it requires the key, sometimes it opens automatically when the door handle is pulled. Cadillac is fantastic!
