Hi Don,

You must be a game warden, or a Kebler elf, or work for the Kennedy's who have a second family compound and distillery hidden away in that forest. Maybe you run a casino?

Glad you could make some progress.

The problem is mechanical with worn pins, and wont go away.
The key is part of the equation! The key can wear as well.
Try all of your keys each way to guess if it's a worn key or worn pins,
(Maybe it's both)

Talk to a locksmith and ask if they can re-pin the tumbler to your key.
(Find out if all your keys are OK using them each way)
Maybe that will work and you can avoid the dreaded Cashechtomy from your Volvo Dealer .

Cheers, Bill
