Ok Everyone here is what I need to do to make this work.

This is on my 560 Sl 1986

1. Using Valet key in the door I lock up the car with the vacuum system.

2. Using Master key I insert it into the trunk cylinder and turn it to the right and remove it without turning it back to vertical.

3. I now unlock the car using the valet key the alarm does not sound when the door is opened.

4. Valet key can now be used to lock and unlock the door and to start the car. (The original goal.)

5. To unlock the trunk and all doors use the master key turn it all the way to the left and then back to vertical.

6. This does not appear to be what my book says but it is the only procedure that works and does not activate the alarm.


Thanks for all of your assistance. Jack M.
