edjunior Posted yesterday at 02:25 AM Report Share Posted yesterday at 02:25 AM I got a message today, after my Edge wouldn't remote start, that the battery in the fob was low. Yeah, so low, it wouldn't remote start. I could still unlock the door though. Got the other fob, and as I figured, it was dead also. Luckily, I had some CR-2025 batteries at the house. Of course I didn't know that each fob took two batteries. Dang. And man, getting the cover off was a test of patience. If I had to get to the emergency key for something real, I think I might have broken the thing. After it broke my fingernails!! Anyway, I finally got them apart, changed the batteries, and all is good. Now to get the second TPMS sensor replaced. It's close to oil change time, so I might just wait until that comes up, or just get the oil change done a little early, and have the TPMS done at the same time. It's all good! 2 Quote Link to comment Share on other sites More sharing options...

Oldandintheway Posted yesterday at 10:52 PM Report Share Posted yesterday at 10:52 PM The Edge FOB takes CR2450 batteries. they are 24mm diameter and 5mm thick The CR2025 is 20mm diameter and 2.5mm thick. Two of those can work in a pinch, but the diameter can be an issue. 1 Quote Link to comment Share on other sites More sharing options...

The other one did have a little trouble holding the top battery, but both fobs work just fine now. Maybe the 2016 used the 2025?? I don't know, but they both work now. 1 Quote Link to comment Share on other sites More sharing options...
omar302 Posted 19 hours ago Report Share Posted 19 hours ago They are two different fob styles. 2015/2016 used the older style (with 2x 2025 batteries) while 2017+ started using the newer type with a single 2450 battery. My 2016 came with the older type and I added fob of the newer style. You can see them side by side In this post I made at the time. 3 Quote Link to comment Share on other sites More sharing options...

Just to clarify and a word of caution to anyone that may consider this suggestion in a pinch - two of the CR2025 stacked would result in a 6v battery which could fry a device designed for 3v. 3 Quote Link to comment Share on other sites More sharing options...
Wubster100 Posted 5 hours ago Report Share Posted 5 hours ago If you need to use CR2025, a better option would be to use tinfoil to create the extra 2.5mm of space. 1 Quote Link to comment Share on other sites More sharing options...

Thanks! I kinda knew that but wasn’t thinking. Good catch. Pay no attention to the man behind the curtain. 😉 1 Quote Link to comment Share on other sites More sharing options...
