So the dome light in my RX300 does not go off when you shut the doors unless you lock the doors. Is this normal? Not a huge problem but I am not in the habit of locking the car when in the garage so it's just a matter of time before I forget and have dead battery the next morning.

This may be related to the locks, not sure. I know a lot of people have had issues with the door locks. My passenger door lock will not work with the key from the outside. I think I can see that the rod is disconnected on the inside of the door so I need to get in there to take a look.

My car only came with one key without the keyless remote. I have figured I am pretty much screwed as far as trying to get a new remote key. Would it be possible to install an aftermarket keyless entry system. Seems like it should work on any car w/ power locks but I dont know if the cars immobilizer will keep something like that from working.

Any tips would be appreciated.
Thanks

 

Please read the sticky RX300 Mega thread ,,, having problems start there

There is a dealer programmable delay on the dome light. If you lock then the light will turn off immediately. Give it couple of minutes and see if the light turns off.

The locks are bit tricky. The key operates rods as well as it makes electrical contact through a switch. The electrical switch energizes the rest of the locks and window down action.

If you read the door lock DIY, the solution is pretty inexpensive.

The imobilizer will prevent the starting/running of the engine.

Light should go off after some times if you do not lock the vehicle. How long you have the car? I think you have the keyless system installed in your RX. Does your key open all doors and globe box? it should be master key and you could programme keyless remote key.

 

I have read the sticky's.

i've had the car a few weeks. The dome light stayed on a few hours the first time i noticed it. My key unlocks the drivers door and the back hatch. It does not open the passenger door. I thought that this was because the rod inside was disconnected. It looked like it when I opened the small screw hole cover on the end of the door. I am going to take a better look today. I will also check to see if the key locks/unlocks the glove box to give me a better idea if it is a master but i don't think it is.

 

So I fixed the passenger door lock. the rod was just disconnected. The key I have unlocks the passenger door, the glove box and the back hatch. Is it safe to assume that they key i have is programmed as a master? still not sure how any of this would affect the dome light. I am thinking that one of the door switches my be bad and the circuit is stuck open.
