Does anyone know what kind of tools work for this kind of gasket lock... I always used hook tools, but it took me very long time to finish the job. Need to look for the right tool for this locking insert tool..? inshop installer 5/24/01

Go to a BMW dealer and order one at the parts department. They are expensive. Try a BMW parts department. One of our installers bought one a few years back then (in 88) they were $50.00. The tool looks like a flat GM insert tool but is wider and has a roller to push down on the insert as the front part spreads the rubber. You have to find a parts person that wants to help you instead of one that just wants to sell filters. I took a GM lace lock tool and modified it to work on these inserts, it needs to be widened at the back so the insert fits.  BG

I use a mallet and fiber stick works great for me.  ws guy 747

Use thin bone stick and spray silicone.  glass buddy

I've always used my trusty Chevy insert tool, it is a little off, but with patience and lots of glass cleaner, it works, especially on a warm day. Also, BMW does sell a tool for it.  mobile pro

I called the dealer they told me they don't have such a tool for this .. they told me to call my glass supplier.  inshop tech

Just did one yesterday and used Chevy truck insert tool with lots of glass cleaner. Took 2 minutes.  Bob
