My Dyna won't start, neither of my proximity security fobs are recognized but I can start the bike by entering the pin.
My fob batteries are 3 yrs old, is it common for both to fail simultaneously? I plan to go to Walmart to buy two #2032 batteries but am I missing something obvious?

 

I'd replace the batteries. It'll drive you nuts having to enter the code all the time.

 

You should be able to start the bike without the fob, I know my local dealership have done it with my last sportster

You can get a two-pack of 2032 (or is ir 2025?) batteries for under $5. Treat yourself to a fresh set.

Oh, and don't store the Fob with the bike, the batteries will last longer, so I hear...

 

I change out my fob batteries every spring and carry a spare on the bike. Can't imagine they would last 3 years anyway.

 

double check your antenna under the seat. extremely unlikely that it came off but, have a look.

looks like:

 

It's recommended that the battery be be changed every 2 years.

also if your second fob isn't in use.. don't put a battery in it. It will drain the same rate as the one you use.

 

Change the fob batteries every 24 months and your good.

 

Yeah. Fob batteries. Change them both.

 

Here's a related story, We were over in Paso Robles, CA....At a motel and none of the bikes in the front parking lot would start, My Bike was in the back, So I rode around and turned it off, And then it would not start, So I got to thinking, And I pushed it just passed the front door of the Motel, It started right up, And so did all the bikes pushed past that point, Weird dead zone......Who knows....
