2015 Power Locks: Heat Issue??
« on: July 08, 2018, 11:48:07 AM »

Has anyone else had their power locks not work in very hot weather??
I stopped yesterday to buy a cold drink and the locks would not work.  The remote was in my pocket so it too was very hot .  The temp was 104F.  At home, sitting in a cool garage, they worked fine.  The batteries are less than 6 months old.

If you want to try to isolate which part of the system is creating the problem, try leaving the bike in the garage and heating the fob up to 100°F - 120°F in an oven (need to let it heat soak for awhile to get all the internal parts up to temperature).  If the locks don't work with the fob heated up and the bike in moderate ambient conditions, at least you will have something to talk about with the fine folks at Harley.  I'm guessing they would come back with something like "that's normal", but for some strange reason I've never had a similar problem with the hundreds of car remote locking systems I've used over the years in very hot conditions.

I'm pretty sure the vendor for the Harley system didn't go to the trouble to invent a unique type of fob just for Harley, but just modified an existing system from the auto industry.  Since high temps don't seem to be a problem for the many millions of remote locking fobs used in the auto industry, I'm guessing the problem lies with the components on the bike (receiver, wiring, actuators).

Try the buttons on the dash. If they work and the key fob doesn't that may be your answer.

If neither works it could be the locks themselves.

I have had mine apart and they are a very simple setup. It is just an actuator and a cable.

Thanks for the replies.
Yesterday it was 97F so I sat both remotes out in the sun on a black oil bucket.  My infra red thermometer said 112F after only 15 minutes but left them in the sun for over an hour.  Took both remotes into the garage and they both worked perfectly, so I don't think the remotes are the issue.  I also rode the bike 85 miles in the 97F temps and everything was working fine.  Must be an issue with the bike at higher temps.  I'll get the books out and trace/check all the connections and see if I find anything. 
The first time this happened the bike was still under warranty and Harley replaced the batteries in both fobs and it seemed to work fine but we haven't had these high temps till this summer.  I did replace the batts this last winter just because they were over a year old.
Didn't think about using the dash buttons.  I'll try that if it acts up again. 
I'll let everyone know if I find anything.
