DaSwede_420 Posted January 3, 2009 Share Posted January 3, 2009 I've got a similar problem on my 1995 GS300, I unhooked the drivers side door "indicator" so i could have the door open and it wouldnt beep while listening to music. Key got in washamashine(thanks to wife) and the dealership said it would be 477.00 to replace a door latch? i have the new key from the dealership, they said they just can't program it cause of the latch being disabled????, can i just take the latch sensor off another door and then program it?, becausethe remote locks & unlocks fine without the latch "sensor" on the driver side door ,you just need that to "program a new key". Any ideas very appreciated!!! :P PEACE!!! Quote Link to comment Share on other sites More sharing options...

justGS300 Posted June 5, 2011 Share Posted June 5, 2011 My second key is acting weird. Its him I cannot program for keyless. Everytime the car sits at home within the range of the second key, it opens all windows. So I thought to reprogram it, but it didnt work. The red light also flashes for no reason. I fixed it by taking the battery out of the second key. I have tried every option there is in the interenet about programming. We'll see how it goes.
