Fob battery warning after changing battery

[Chapbuick]

Are there any known issues with the key fobs for 2020 enclave? I changed the battery in my fob after getting the error message saying low battery and I’m still getting the message when I start the car.

Check the new battery with a voltmeter.
The new and old battery have the same part number?

Hi, I recently bought a 2020 Enclave (2.5 weeks ago) and have the same issue with both fobs. My fob (F1) has had the battery replaced twice, my husbands (F2) 1x. Car gives warning with both fobs every time we start it. My local Buick dealer changed the batteries and checked the batteries with a voltmeter.

Are you still covered by the bumper to bumper warranty? Did the dealer offer to resolve the issue?

I do not think we are, car is just at 3 yrs and has just under 35k miles. Dealer isn't really much help- at least have not come out and said they would take care of it. Just emailing me a bunch of tricks to try: try another battery, try the other fob, reset the display. I have done all of that shy of restoring the car to factory settings (through infotainment system- which honestly will likely just restore THAT). I asked my husband to call them and talk to them.

To clarify, the Buick dealer we bought it from is about 35-40 minutes from our hours. I work 40-45 minutes from home the OTHER direction, and happen to have another Buick dealer 10 minutes from my work. the dealer close to my work is where I took it to get the batteries changed. Trying to determine if its better to take it back to that one, or get off work early to take it to the dealer we bought from. Going to depend how the conversation goes and if they will take care of the problem for us.


Still curious what is going on, is this a known issue, what has the fix been? Is there any harm being done continuing to drive the car with the message (the manual advises to change the battery ASAP and not to continue to drive it, granted the battery isn't actually needing replaced) ?

One of the dealers has to run diagnostics. You don't want it getting to the point where the message is can not detect remote. The selling dealer didn't give you a 30 day bumper to bumper warranty?

I am having the same issue on my 2020 Buick Enclave. Both Fobs have had the batteries replaced twice and the warning continues. I had zero issues with this until about a month ago and bought my Buick new in 2020. Unfortunately, I am outside of warranty.

Same issue here. Both fobs come up with the low battery warning and we are under warranty and took it in to the dealership we bought it from and they pointed us to YouTube to fix the issue. Not very good service I have to say.

I CANNOT believe they referred you to YouTube!!! I'd try another Buick dealer. They all have to honor your warranty.

We have been fighting the same issue for a year now. Our dealer has been very helpful and tried many things, replace the fobs, replace the body control module, and check all connections. Still getting the error. Has anyone had luck diagnosing? Can you share the YouTube link?

Can you share the link to the video?

I have the same problem. Keep replacing the battery in the fob and now I can only start my car by putting it in the transmitter slot in the center console. Is there a link here we can use?

I had the same problem with the message not going away.
Someone else posted on a different forum to use the unlock button on the key fob instead of unlocking with the door handle. It resets the key fob to the car. I tried it and it worked. No longer have the message.

I have been having this same thing happen. I just tried using the keyfob to unlock and did it again while inside the car (lock, then unlock using fob) and I think it worked.

I’ve had the same issue on my 2021 Enclave. Someone on this thread suggested using the key fob to lock and unlock the car vs unlocking by pushing the button on the car door. So far it has cleared the message.

Came here with the same issue. Also tried locking and unlocking with the key fob as a remote, and that seems to have cleared the issue. What a simple fix, thanks for posting! Hopefully this is a long term fix.

Just went and tried this. It cleared the error message.

Sounds like a bunch of batteries put in upside down?

The lock and unlock with the fob works!

This is strange. It's almost as though the BCM does not perform a new FOB 'battery-health-check' until a lock/unlock is executed from the FOB (or something similar).
