H3 Fobs dead after replacing batteries

[AlphaLife]

I got my Alpha a few months back and it came without key fobs. Bought a pair online and got em programmed at the dealer. They worked for a few months but only at close range and began to rarely work so I replaced the batteries. Neither works now. Any suggestions?

In 8 yrs with 2 H3s, I've never had to replace a battery in the OEM remotes, and they work through walls from 50 yards away.

Were the ones you bought online used or aftermarket? Could be the issue there in itself.

Don't know about the H3, but I know the ones for the Corvette have to be reprogrammed when the batteries are changed. YouTube it. I know there are lots of vides for syncing fobs.

I've changed the H3's fob batteries with no issues, and no need for reprogramming. I do wonder if you got OEM or aftermarket, like Zach brought up.

I bought them online and had them programmed at the dealer. They're probably not OEM. That's probably the issue like you said.

Did you try the personalization reset as I describe on X?

 

[Zach]

Did they both quit working at the same time? The only working at close range is odd too. Replacing the batteries, you don't have to get them reprogrammed.

Reprogramminig is normally not required, but they were noted to drop the personalization and revert to Mode 4, which is bacially they do nothing. That's why I was wondering if he tried the personalization procedure I noted on X.
