Yesterday I was at a ceremony on a high peak that had a lot of cell phone towers/microwave antennas/radio antennas around the area where the ceremony took place. When it was time to leave I was unable to disarm my security system either with the key fob or manually using the turn signals. Even went so far as to replace the key fob battery which I knew was not going to work from previous experiance with this problem. Lucky it was all down hill, I was able to get a bud to give me a push to get further down the hill to get away from what ever antenna was causing interference with my security system. There was a lady with a newer Corvette parked near me that was unable to use the Key fob to get into her car, I guess boths fobs work on a similar freq. I stopped by the Dealer and asked about this problem. The service writter wanted to know if I was down town. It appears Harleys with factory securiy systems have the same problem in and around downtown San Diego, and at a couple of the local military bases. The local dealers know about this problem, and claim there is nothing that can be done to stop it, except move your bike to a different area or replace the TSSM. $125 for the TSSM and 2 hours labor. Anyone ever hear of this problem before. Ever heard of a way to stop it from happening? Do you think the MOCO would be interested in knowing their security system is suseptable to interferance? It irritates me that I was so demanding to have the factory security system installed, only to find out how much grief it would give me. Could I install a faraday cage around the TSSM and manually input the security code?
