I dropped one of my keys (1993 SC300) in a parking lot and the little button that locks/unlocks the doors popped off and disappeared. The spring now sticks out through the hole.

Any idea where I can get a replacement button?

 

no i dont but that happened to me a year ago and ive been living with it ever since, just use a smaller key to push the button under the spring

if u do find where to get one please let me know --i might as well fix mine also lol

thanks and good luck

 

Either get a new key or get creative I guess, I doubt Lexus sell just the replacement button. Might be a great time to go aftermarket for your alarm too.
