I bought an extra in the event I lost my first one; this is a very well made item.

Spare
Got a spare to attach to my key because the dealership couldn't find the original under the seat.

Tool Fail
First time I used the tool for an oil change the small metal piece that fits into the tool cracked off. Or fell out. I don't know but it isn't there anymore. It did not last long. I can't unlock the plug. The tool looks clean in the hole where the lock should be I think it was fitted and glued, not one piece . On the positive side; Leak stopped. Looks clean and flush. Negatives; the tool is a fail. Why do we need the tool ? Who would sabotage the oil? Can I use something else to open it? Is the tool guaranteed ? I emailed, yet to find out. I ordered it in November . Only one oil change! Should unlock with an Hex lock something I can easily replace. Getting rid of the plastic insert in the cyclinder was tremendous. That was was a piece of junk. BMW should have addressed this. There should have been a class action suit. Installing wasn't easy as the YouTube video indicated. It still leaked a lot until I put in a larger o ring

Nice but unnecessary
The fit and finish of the "locking key" are fine, but the cap assembly should have been left without a "lock." Just something else to lose and create a hassle. The cap can still be opened without the key, so it is totally unnecessary. In 50 years of riding, I've never heard of anyone who had a problem with a vandal accessing the oil filler.

If you buy the Wunderlich plug, buy this tool too!
If you do buy the Wunderlich secure oil filler plug, maintain your sanity by buying a spare tool. Put it in your toolbox at home. Life is crazy enough as it is!

Redundancy = good
I added the Wunderlich oil plug a year or so ago. After a 5,000 mile trip this last summer I decided I should probably carry a spare \"key\" for it, along with my back-up ignition key. You never know....
