Smart Security System is rated 5.0 out of 5 by 6.
Rated 5 out of 5 by from Peace of mind I bought this security system for peace of mind. I love the fact that it arms automatically as sometime I forget to lock the ignition. Had the dealership install and price of install was not much. Since the fobs had to be programmed, I just let them do the whole job. Looking at what was involved, it is not a difficult install to do yourself, but since the dealership needs to program it's fobs, why bother.

Rated 5 out of 5 by from Great product I had this and the sierin installed on my fat boy as it did not come from the factory with it. Great product works well. Install was a little more than expected.

Rated 5 out of 5 by from Security System Great product. Since it's a factory option it's all plug-n-play. No cutting or splicing of wiring on the bike. The only down side is that you have to get the dealer to install it and pair the FOBs. It took an hour for the dealer to install the BCM, siren and pair the pager unit. They charged $75 to install everything at my local dealership.

I bought a 2014 FLSTNSE CVO with 2000 mi on it, but the security system light doesn't blink and the bike starts even with the fob over 50 feet away.

I see the antenna for the security system, but where is the system itself and what can I do to get it to work?

Starting engine in parked position

Do you have to upright the bike to start the engine? I think the decription reads you get on bike and upright and then it will start. Will it stsrt while setting on kickstand?
Asked by: kcb3rd
In order to start your '16 FLSTFB, you either need the bike to be in Neutral or you have to pull the clutch in manually (if in gear). You can be on the bike or it can be in the parked position and on the jiffy stand.

Yes, the dealership will need to do some programming to the unit. It is a fairly quick install and shouldn't take an experienced very long at all.

security system install cert.

Is there a certification card that comes with the security system that I can give to my insurance co. When I told them I had one installed by a dealer so as to get the insurance discount they told me to hane the dealer fill out the certification that as a rule comes with alarms. the dealer didn't know what I was talking about, but without a cert. signed by the dealer stating they installed the alarm on my bike I cannot receive the discount from my vehicle insurance company. Is there such a certtification card??

I just made a copy of the invoice showing the system and the dealer installed and sent to my insurance company. No issues
