Last night my car remote would not work. "Battery" I thought. I tried the spare remote, still nothing. So I locked the car with the key with no problem.
This morning I tried again and everything worked fine.
yes signal, if it happens again, get in car put key in egnition and only turn once and lock car with remote whilst still in egnition then unlock, should get signal back.
And sometimes the battery connection in the remote works loose , the solder cracks and parts.Easily repaired by someone who has a small tip soldering iron.
