Ordered a Haynes manual last week.

Could not wait for the book and tried again this weekend. I was lucky enough to get the handle out and following door swap was cake-walk.

Different from the lock on 850 that lock cylinder can be removed (with a key), there is not obvious way to separate 1999 v70 lock cylinder from its shell. There is a steel strip that holds lock cylinder shell in place. It can be seen from the access hole and there may be a special tool that can be used to pull the strip up to release the lock.

What I did was:

1. remove the 2 screws that holds the door handle.
2. pull handle straight out as much as you can. At the point it can not be pulled further, twist handle downwards. By trial and error, you will be able to slip the handle out of door/lock lever. and the handle is free to be taken out.
3. loosen the steel strip holding the lock shell, remove the plastic cover (for the key hole) and take out the lock cylinder with shell.
