We have a 2018 RDX Advance with around 15k miles. About 1-2 months ago we started getting the "Low Battery" message for the key fob on the dash. Replaced the battery for the remote fob at that time and all seemed well until earlier this week. Same problem has appeared again and now I'm wondering if there's a bigger problem here possibly with the key fob itself. For reference the Driver 2 Key fob hasn't had a single problem to date. Anyone have any ideas? I saw another post here about the same problem but the post went unresolved with no updates.

 

I also have a 2018. Do you or someone else carry the 2nd fob with you in the car? If so, try replacing the battery in the 2nd fob also. My experience was that my wife keeps the 2nd fob in her purse. Some time ago I got a low battery message, changed the battery, and... Still got the low battery message when she was with me in the car, but not when I was alone. Just for the heck of it I changed the battery in her fob also.. No more message, and no idea why that worked but it did.

 

The 2nd key sits in a cupboard and doesn't get used too often. It's never in the vehicle at the same time as the 1 key.

 

Is the key FOB near or in the car when you are at home? Some people leave their key FOB in their car when it is parked in their garage. If so, there is a continual back and forth communication between the car and FOB. Another thought is you might be purchasing old batteries. Make sure you get a fresh one.

 

Battery was replaced by Acura dealer, both keys are inside the house far from the vehicle.

 

Batteries from the dealership are most likely leftovers from the dollar store, dealers are notorious for being cheapskates. If you can't figure out the rest, then higher education seems to be irrelevant to the masses, best of luck mate

 

You alright guy? You seem pretty antagonistic, why even comment at all.

I just want to know if other people had problems with these key fobs before taking another 2 hour trip to the dealer.

 

whoa, how much do they charge for that?

 

Acura Dealer changed My fob battery at no cost.

 

I think it was 5 whole dollars!

 

I went to Walmart this weekend. Purchased a 2-pack of Energizer CR2032 batteries for $4.29. I came home, opened up both remotes, changed the battery and all works well now. If you have doubt about how to do this you can:

1) Open owners manual to section that gives step by step instructions
2) Go to YouTube and find numerous videos that show you how to do this.

Using both above methods, an 8 year old could have done this. Sort of why some people who responded picked on you a bit. Sure it might have only cost $5, but the time and trouble and likelihood of them using an old battery is just not worth it. This is a job that DIY comes out much better and cheaper.

 

+1 on Crashmaster post. Changing the batteries is really, really easy--the manual tells you how to open the case and do it. There are lots of outdated batteries or brand knockoffs out there, and it is best by far to go get a reputable brand at the store and install it yourself in both fobs at the same time. No need to involve a dealer and all the time and effort that takes.

 

Everyone can replace the battery with ease. The batteries in our advance went out (low battery sign) around 15k. I replaced both of them the same time.

 

My mechanic replaced the battery last month. Just started getting the low battery message again after less than 30 days. 2017 RDX. Just replaced myself.
