Hello Pete-
We checked the cable, looks good! There is a little corrosion in the positive side. What would be your next suggestions? Can we remove the key from the remote key to start the car? Is there a way to test if the battery is dead without towing the car to the shop?
Lexus Mechanic: Pete, Technician replied 6 months ago

Is this a push button start?

Do you have dome lights coming on at all with the door open?

Customer reply replied 6 months ago
It is a push button start. No lights at all when doors are open.
Lexus Mechanic: Pete, Technician replied 6 months ago

Do you have a test light or multi meter to test electrical at all?

No we don’t!
Lexus Mechanic: Pete, Technician replied 6 months ago

With no power at all this has to be either an issue with a battery cable connection at or leading from the battery itself to the fuse panel or an issue with the under hood fuse panel itself.In order to help find out what is causing this issue here, you will need a test light or multi meter to test the electrical signals.You have a black/blue large wire at the under hood fuse panel that runs from the battery.This wire should have at or near 12 volts DC at all times key on or off.You have a black wire leading from the ground to the engine block and this should be clean and tight.If you have these signals then the fault would have to be in the under hood fuse panel itself with damaged wiring or corrosion with the wiring or terminals under the fuse panel and the panel would need to be removed and inspected and repaired or removed and replaced.

Let me know if you need anything else and feel free to rate my help here or above ( should be a link to click on ) as this is how I receive credit for my time, this can be done at any time and you can still come back here and reply if needed.Your 5-star rating is appreciated

Thanks Pete
