Apparently this is a special order part, it's a gel type battery that is not standard and not kept in stock and will not arrive for about a week. Getting a loaner in the meantime.

The key was not the problem.

When i tried to start the car, it said "Key Not Detected". I checked the battery on the Key and it seemed to be fine. The light lit up when pressing the lock unlock buttons, but the doors would not respond anymore. One thing I noticed right away is that the break could not be pressed, pressure in the break lines.

I called Lexus Roadside Assistance and they tried some troubleshooting. Pressing the Key on the power button and trying to start the car. It would sometimes say "Key Not Detected" but now had stopped responding completely. It tried to see if the battery was dead. I turned on the Interior lights, they worked but were very dim. I tried Hazzard Lights, which would flutter and only light up on the Left Side of the car. Sometimes they would stay on, sometimes they would blink a couple times and then turn off.

Lexus thought the battery was dead. When AAA came, they tried to give the car a boost. It didn't take. It didn't respond at all to the boost. BTW, I waited an hour and a half for AAA to get there. AAA could not tow the car until they had confirmation from the dispatcher and the driver would not wait for the confirmation and left telling me he had another call. Lexus called back and told me they had confirmed with AAA and they will tow the car. I told them the driver had left. I had to wait for another Tow Truck, which did only take a half hour.

The guy got there and actually told me he saw the same thing happen recently to a Prius. He said it wasn't a battery problem but that he tried some combination with the power button and break and key presses and was eventually able to start the car. Nothing worked with mine.

This happened on a Saturday at 6:00pm. All the Lexus dealerships were closed. At first Lexus was asking me where they can leave the car. I told them I live in an apartment building with an underground parking garage. There is no way they would be able to get my car into my spot with a tow truck. The operator told me I would have to pay to store the car at AAA until Monday, and then have the car towed to a Dealership for service. This was while still waiting for the first Tow Truck. I called back when the Tow Truck arrived and this time Lexus agreed to pay to store the car until Monday and tow it to a dealership for service, but, because it's a Saturday, I don't have a loaner! I have to go to work this morning with no car! The car has 5,000 miles on it and was just in for service for 5K maintenance last Saturday!

I got a new car for the Peace of Mind that things like this would not happen. I got a premium car so that I would have good roadside assistance and a loaner car. This Sucks!

One more thing. I tried the SOS button in my car, since I have Lexus Assist. IT WOULD NOT WORK. It had no power. It's a good thing I have a smartphone and was able to find a number online.
