Service writers = thieves...when they can get away with it! Always question what they are trying to sell you and the price. This is unless you absolutely, 100%, know and trust him/her. Sorry, back to the autolock. I haven't owned a BMW with both auto lock/unlock. Just lock and it's dealer programmable. If you want both features, you can simply add a module that has both features and you are good to go. Our Accord had keyless but no auto lock/unlock so I just added in an old alarm module and enabled the features.
