That happened to my other cars. It seems like the fob goes into "sleep" mode to conserve battery either because it's running low, or you haven't used the car in a while with that key.I haven't seen it but I think I've read that can happen when the battery in the key fob is getting low.
Hmmmmm. My key fob is working just fine. In fact, I can unlock the car using the fob at a distance of at least 80 yards. You’d think this would be happening more often if the battery is low but it’s only happened twice in the last two months.I've also experienced this when the FOB battery is low.
If you replace the batteries, pay close attention to their polarity when you take out the old ones. Drove myself nuts trying to change my wife's batteries when I didn't.
If you get a new fob battery and put it in the drawer, you will have it available to change when needed.Ok. I’m going to wait until this happens one more time and then I’ll replace the battery.
So you’re saying that the van’s ability to detect the key fob is an active circuit in the key fob and not a passive one like RFID, right?There have been similar threads.
You should be aware that AFAIK, the fob has two independent functions.
The buttons for door lock/unlock, remote start, etc., are what I characterize as "on demand" features and the signal can travel hundreds of feet.
The other circuit is constantly on and allows the van to let you unlock it by touching the doorhandles when you are close to it and recognizes that the fob is inside the van and allows you to start the engine.
I would keep a name brand battery handy.
If the issue repeats with a fresh battery, you may have an issue with the fob's local field circuit and need to replace the fob.
If it happens with both fobs, the problem may be with the van's detection circuit or it may be more complicated.....
Here is another thread to read.So you’re saying that the van’s ability to detect the key fob is an active circuit in the key fob and not a passive one like RFID, right?
