R129 SL500 immobilizer/security module removal and location.

Short video showing the location and removal process for a Siemens 5WK4680, 129-820-37-67 security module/immobilizer unit. I had to remove this on my project car, I broke the transmission module inside the key fob, so a local locksmith needs to solder a new chip on the board for me. Hopefully somebody finds this helpful.
