Key Fob Not Responding To My Harley-Davidson: Why?

Harley-Davidson owners enjoy the keyless operation of their bikes, and sometimes they forget that the key fob needs attention. The key fob operates on a battery that, over time, runs out. Although it can last long, most bike owners remember this once they are stuck in odd places.

Another issue could be that white noise interferes with your key fob's frequency. Signals might fail, but you can solve the problem if the key fob has frequency hopping. The hopping allows the key fob to use another frequency to start your bike if the others are not working.

What Type Of Battery Does A Key Fob Use?

Harley Davidsons use a standard cell battery similar to other gadgets. When replacing your key fob's battery, you'll need to know which type works. 

You can open the key fob and look at the digits on the cell battery. However, Harley Davidson's key fobs use a CR2032 cell battery. Your user manual has the number indicated there, also.

Alternatively, approach any dealership for assistance in replacing the battery for a nominal fee.

How Long Do Key Fob Batteries Last?

Can You Use Another Battery Type In A Key Fob?

A different battery might work in a Harley Davidson key fob. But, more often than not, the battery, other than a CR2032, won't work.

The other battery might be thinner or smaller than the one meant for the key fob. It won't make contact, and no signal will come from the key fob to the bike.

Why Do Key Fobs Have Frequencies?

Frequencies are used as a security measure for your lovely toy. The frequency secures your bike, and lights start flashing if you move it without deactivating the alarm with a key fob or PIN.

Depending on your Harley Davidson, the flashing lights might be accompanied by a siren to alert the owner. Although the technology isn't new, it remains a mystery to many bike users.

The key fob might work if the water didn't have time to wreak havoc. But, you might realize with time that it has voltage spikes or battery failure. You might resolve to purchase a new key fob for your Harley Davidson if you can't rescue the one you have.
