Easy FOB Battery Replacement: A Step-by-Step Guide
Introduction: The key fob (FOB) is an indispensable companion for many modern vehicles, including Harley Davdison models from the 2000s onwards.
Before you start changing the button cell, please make sure that you are out of range of the transponder to the motorcycle. This prevents unwanted interaction with the vehicle while changing the battery.
A common problem with FOBs is a dead battery. Fortunately, replacing the battery is a simple process that you can do yourself. Here we will show you how to change the battery of a FOB quickly and easily.
Step-by-step instructions for changing the battery:
Opening the FOB:Start by carefully pushing both halves of the key apart with a screwdriver.Removing the old battery:Take out the old battery. Be careful not to damage the contacts or the interior of the FOB.Inserting the new battery:Place a new CR2032 battery into the FOB with the writing facing down.
This CR2023 "button cell" battery type is available at most Harley stores, electronics stores, hardware stores or online.
Assembling the FOB: Then press both halves of the FOB firmly together again. Make sure they click into place properly and there is no gap.Conclusion: Changing the FOB battery is a quick and hassle-free process that ensures your key fob is always functional. With these simple instructions you can save time and money and ensure the longevity of your FOB.
So you won't be completely stupid during a trip in the middle of the season if you simply replace the FOB battery at the beginning of the year instead of waiting for your Harley Davidson to be parked in a fully parked parking lot and the annoying alarm system to go off because the battery is in the transponder is empty.
So you want to appear positive and not attract negative attention everywhere.
Let's now come to another problematic transponder topic, the holidaymakers and long-distance drivers among you who have already traveled to southern countries such as Italy or France with your Harley and one or the other has probably already had it on His H-D could no longer start at a toll booth, a rest area or in the ferry port or near radio masts.
Why is the newbie asking himself now? Because previously a very simple frequency was used between the transponder and the motorcycle and this was disturbed by the radio connections see above. Nothing was possible except pushing it 1km away from the gas station or putting it behind a concrete wall. There were even some who called the ADAC and had them towed.
However, it doesn't have to come to that.
We have a little trick for you:
For the older models with "pusher" FOB:
Never switch the motorcycle off with the ignition key when stopping or refueling or interrupt the ignition with the rotary switch on the tank panel!
In this case, it can only be switched off with the kill switch at the top of the right switch housing.
Now the smart-ass people will say: that's not good for the ignition coil.
Yes, you're right, the ignition coil doesn't like it when it receives power for too long without the engine even running.
However, we are talking here about a refueling or payment process and not about a half-hour siesta.
That's why if you have a healthy motorcycle and a healthy ignition coil, you don't have to worry if it gets juice for 2-3 minutes.
By the way, you can also make this problem easier by simply installing a circuit breaker.
See: Isolator switch 12V 50A item number YC101880-60 in our online shop. Available from Inmaxwetrust.com
This is also installed on our Harleys and has been in use since 2019. There is no easier way to solve a problem.
For the newer models with FOB without a pusher, depending on the model from 2007, we also recommend the procedure with the kill switch at gas stations, rest areas and radio masts. The main thing is that the FOB is not logged out, so it must be in the immediate vicinity of the vehicle.
So please take a close look at this circuit breaker, you can also use it as a pure ignition lock with ON/OFF function for show bikes etc.
Can also be used as an anti-theft device on motorcycles, jet skis, ski doos and cars, motorhomes and tractors
We have thus interrupted the ground from the starter, for example, the switch is hidden in the glove compartment. This means we don't have any error messages despite the Canbus in the car and a thief can't steal with a car without a starter.
