Hello,

For my 2015 LX I believe the wireless key fob's electronics may be damaged. After replacing the battery the red light goes on for 5-10 seconds then goes off. After that pressing buttons doesn't do anything.

Is there a way to replace just the fob but keep the physical key?

Thanks.

 

Take the battery out. There, FOB is deactivated. The key should(?) work on the doors but I'm not sure if it will start the car without the electronics being active.

 

I was looking for a way to replace the electronic fob. Replacements I've found have a blank key.

 

Had a similar situation recently with my '16 LX when the battery on one of the keys died.

I thought I could just pop in a new battery and be good as new. When I did, got the same red light as you did and no remote capability. Would still start the car, but remote door opening and locking were gone.

My understanding is once the key battery dies, it needs to be reprogrammed to the vehicle to get remote capability back.

I knew my other key battery was going to die soon, so I got a key reprogrammer and reprogrammed both keys myself after replacing the battery in the 2nd one.

Local Honda dealer wanted $185 to reprogram keys. Key reprogrammer cost me about half that.

I really didn't want to go down the key reprogrammer route, but didn't have much choice unless I didn't want remote opening/locking.

 

2015 LX, same thing happened to me with the locks. One fob, the battery died and I started using the other one and forgot about it until that died too. So, I replaced both batteries and the remote locks wouldn't work on either one now. I went to youtube and forgot which video I watched but did something like this.


The first time it didn't work so I tried it again and it started to lock, but not unlock or vice versa, I can't remember. I guess I just started using the key to maybe start the car and kept trying to cycle the locks and it finally came back after a little while and both lock/unlock started working fine. I had to do that trick with the second one too in order to get it to where the locks worked intermittent like before, and it finally came back to normal after I kept trying to cycle it.

When I bought the car, the dealer told me to alternate the keys once in a while. I thought it had to do with the batteries, but as bargainguy alluded to, I guess they lose touch with the car (so to speak) and you have to reprogram them back in a way if they aren't used for a long time or if the batteries die so the car recognizes them again.

Some of the comments in the video I linked stated that it didn't work, but they did it faster than he did and it worked by doing that.
