I tried to change to security code on my 2006 Dyna wide glide. I followed the service manual and couldn't get a display on the speedometer.The first time I tried in the process the bike locked on security mode and there was no way of unlocking with key fob or any other methods. I went out and purchased a new TSSM and installed and did password learn and programmed two fobs. Bike runs fine now and I can arm and disarm security system with key fobs. I still cannot access area to change security code and followed the steps in service manual. I stopped when I got no speedometer number display to add a new code. Any suggestions to remedy this problem?
