Safe to rely only on activity key?
I keep the larger key with buttons at home in a safe drawer and only is the activity key. Lately, I've had a few times where my car doesn't recognize the key for a minute or two while I'm frustratingly pulling on the door handle . Eventually it wakes up , but I'm wondering if the problem could get worse . I'm assuming the car will alert me when the battery in the key starts to get low?? My TCAM has been having a bit of trouble lately too, does that module have anything to keys?
