You hit it on the head! I had lexus come out and sure enough, the latch somehow managed to break since its last use (2 weeks ago)! Well, I guess the hardest part was identifying the problem. The non-responding fob key is explainable by way of a weak alternator. What a convenient combination :chairshot: Nonetheless, thanks a ton guys!

Ok, I changed the battery in the FOB to no avail, unfortunately. The part that baffles me is that I can't even unlock the door manually. Does anyone know if the 2004 RX's lock mechanism is integrated with some sort of electric component? I'm thinking this only because when the driver side door is unlocked it simultaneously unlocks all other doors. If for some odd reason my battery is also dead that would disable entry entirely. Thanks

Thread title should say: Car not responding to fob key, manual lock not responding to key Hi all, I've seen similar posts, but none in regards to this problem specifically. The light on the fob key flashes when pushed, but the car does not respond. From this I can only assume there is no problem with the key. However, when I place the key in the lock, the lock fails to respond--it neither locks nor unlocks the car. I tried some WD40 on the key with no luck. I want to say there's a problem with the lock but I can't see how that would effect the car's response to the fob key. Here's the kicker: My model Rx (it's a 2004) has only 1 key hole which is located on the driver side door. No passenger key hole and no rear hatch key hole. So, as it stands, I'm locked out of my car! Thanks for the help!
