2017 QX70
Hello all. I have a silly, borderline ignorant question for you all. Due to Covid I hadn't driven my car in a while. So low and behold I went out to start it and it was completely dead. AAA came out and gave me a jump and it started right up. Battery is only about 6 months old. So I let it run and recharge for quite some time. So I go out to start it today and my keyfob has no juice. No door unlock no nothing. Went to start the car and it said no key found. I stuck it in the slot and it started right away. Figured maybe it was just the battery in the fob. Then I grabbed my spare and no juice there. So my question is do I have to reprogram the keys or something since battery died or do I just need to replace both batteries in both fobs? Thanks all.
