BMW Mechanical Key Generation / Programming Transponders for EWS Systems - A Field Guide - By: Travis Wright - A detailed written and visual guide to BMW locks and programming. ---- Hello. My name is Travis Wright and I have been an Automotive Locksmith for twelve years. When I first started, BMW was a difficult vehicle for me to learn. I was able to open them pretty fast with the famous long reach tool when they were locked. However if the keys were in the trunk, I was unable to do anything with the vehicle. Now, I love this vehicle. With the right tools and practice, I can unlock these vehicles quickly and easily.
