2nd Key Fob Proximity

So my buddy ordered a second key fob for his GA. His wife likes to have access to the bike for those special purchases. The dealer told him that he could not carry the 2 fobs within 1 meter of each other for a extended period of time as this would corrupt the key fobs. This according to the dealer was per BMW. Does anybody know if there is any truth to this, or have personal experience to debunk it? My buddy was a bit surprised by this information as was I. I assumed that there was just a passive chip in the key that the security system read. I'm not sure how 2 passive chips could corrupt each other.


Thanks,
Mike

I got 2 fobs with my used 2016 bike I bought last year. I store them side by side in a drawer of my tool box out in the garage. They are far enough away from the bike so as not to be sending signals to it but in way over a year they both work just fine.

Labor Day weekend my wife and I will be going on a trip and like you she will carry one and I will have the other. This will be the first time both fobs will be together and close to the bike for an extended period of time. I have had them together and close to the bike for short periods of time with no problems.

I have my emergency key hidden on the bike so I better make sure it's still there before this trip, I may need to use it if your dealer is correct.

This is a good topic. I was thinking on ordering a second fob cause sadly, the GA comes only with one. I do have the emergency plastic key. My older GTLE came with 2. You would think paying so much for them, at least getting 2 !!! LOL. It is around 250.00 and I am not sure if I can program it at home. I never checked.

So why doesn't the same corruption happen in all of our keyless cars? Is it not the same technology? This would be an actual and well documented problem.

FOBs are just a Bluetooth frequency receiver/transmitter). I could see how they could drive the bike nuts, but not each other.

I recommend creating a Faraday box for your wife's spare. An Altoid tin covered in a layer of tin foil is thin, easy to carry, and should do the trick.

Sounds like dealer hearsay & rumor. My BMW automobile can have the two fobs together and they both work fine.

A note of caution to single riders with 2 fobs. Don't walk away from your bike leaving one of them stashed on the bike. That would leave the bike vulnerable to a thief. That is why you only need one fob plus the E key. Giving an extra fob to a passenger is OK.

What sorcery is this? 2 key FOBS that will explode if put together.

I have two FOB's and on long trips one is in my wife's jacket pocket and the other one is in mine. Thus far not an issue that I'm aware of.

This would be the same scenario that my friend would have. Kind of curious has to how long you've been doing this without a issue.
