VERY HAPPY !!!!! A must buy item for the W123 crowd.

I found a key in my glovebox to "Red", and it was to the car but it was broken. The downside was this type of key is the plastic casted head and not the removable type of key. Half of the plastic head was missing.

Being impatient I used the dremel tool and not the file since a perfect fit is a must. I may be off a few 1000th's of an inch, and there is the ever so slightest amount of play, barely noticeable unless you twist and pull the key; however, still virtually no play.

Saved a key and got a super cool key in the process.

If you have the non-removable type of key, you have to shave off the "wings" of the key and square them up. I doubt I invested 15 minutes with the dremel.
