Thanks for enabling my lazyness!

 

Oh, well, it’s now our fault for enabling your laziness?
I bet when you get wasted it’s the barman’s fault for enabling your drinking habits, isn’t it?

 

Just another reaso in a long list of reasons to not buy a new, high tech, way too much to go wrong that you can't fix in a parking lot or shoulder of the road bike.

 

Unlike my smoke detectors, I change my FOB batteries when they're dead. I can't see throwing away a perfectly good battery if I don't have to. I have had to use the code method to start up several times. Not that big a deal, as long as you remember the procedure and code. I use the last 5 digits of my social for the code. It's a number I've known my whole life. Keep the procedure in your wallet. Be prepared! You never know when you might have a FOB fail or get damaged or lost. Or the battery goes dead long before you thought it would, out in the middle of nowhere.

 

The batteries are small enough that it's nothing to throw one in a tool pouch or wherever. I had a problem when I had my Fat bob because I kept my Fob on the same side of my pants as my cell phone and the battery wore out in only four months or so. The bike started acting weird and not always wanting to start or starting only after I walked towards and away from the bike several times. After replacing the battery everything was back to normal. Now I just carry a spare at all times just in case.

 

One think to keep in mind is that the FOB “wakes up” when it receives Low Frequency signals (125 kHz).
In close proximity many devices that usually transmit on totally different frequencies have a harmonic component of their signal that coincides with the FOB receiving frequency and is high enough to wake the FOB up.
And when the FOB is “awake’ it tries to decipher the signal and consumes power.

Known to me devices that can keep the FOB up from close distance are cell phones and mostly computer displays – if you leave your fob next to your computer at work the battery will go down within couple of months.
I’ve been using harley fobs since 2001, mine usually last couple of years. The spare ones I kept in the closed were good after sitting for 4 years.

 

So if you keep your fob within 6-10 feet of your bike in your garage will it drain the battery? I realize this is an old thread but I've been going through batteries every month even tho I've alternated fobs and battery providers.
