About a couple of months ago I noticed that the remote (wireless) key of my 1999 RX300 stopped working intermittently. I changed the battery in the key fob, but saw no improvement. More recently, it has almost stopped working. I have to insert the key into the door to open the car. (There is a tiny LED on the key, which does blink when I press any of the buttons.) Anybody seen this problem or have any suggestions? Thank you.
