Yeah I'm gonna pass on the call, didn't realize it was 26$ haha, and no I only have this key fob.
Lexus Mechanic: Victor, ASE Certified Technician replied 1 year ago

Yeah, I understand.

Does the engine crank over, but not start?

Ask Your Own Lexus Question
Customer reply replied 1 year ago
No crank over, no sound nothingI also just replaced the battery in the fob and the car if that helps at all. Like the car battery about 2 months ago and the key fob today since the issue.
Lexus Mechanic: Victor, ASE Certified Technician replied 1 year ago

Does anything else on the car not working normally?

Ask Your Own Lexus Question
Customer reply replied 1 year ago
No normally the car works perfectly, just yesterday I tried to unlock the car and I got a red light on my fob, after manually getting into the car, it won't start.
Lexus Mechanic: Victor, ASE Certified Technician replied 1 year ago

Are you able to atleast ignition on?

Ask Your Own Lexus Question
Customer reply replied 1 year ago
No, there is no keyhole for my ignition and when I hold the fob up to the ignition button nothing happens.
Lexus Mechanic: Victor, ASE Certified Technician replied 1 year ago

Yes, that's what I meant. Ignition on by pressing the button twice.

Ask Your Own Lexus Question
Customer reply replied 1 year ago
I can try pressing it twice. One sec.
Lexus Mechanic: Victor, ASE Certified Technician replied 1 year ago

Is there voltage at the IGT1 and IGT6 wire while cranking? Should be less than 4.5V.

Sorry ignore that post.

Ask Your Own Lexus Question
Customer reply replied 1 year ago
Okay. Yeah nothing happened when I pressed it twice
Lexus Mechanic: Victor, ASE Certified Technician replied 1 year ago

Ok, sounds like you have a popped fuse.

Or maybe loose battery terminal.

Double check the battery terminals.

Even though battery is new, I would rule out a dead battery as well. Do the headlights turn on?

Ask Your Own Lexus Question
Customer reply replied 1 year ago
The headlight do not turn onthe terminals look good
Lexus Mechanic: Victor, ASE Certified Technician replied 1 year ago

Sounds like the battery is dead.

Try jumping it please.

Ask Your Own Lexus Question
Customer reply replied 1 year ago

Lexus Mechanic: Victor, ASE Certified Technician replied 1 year ago

Hey victor! It's Jake! So I jumped the car and my horn just went blaring offmy fob would not stop the blaring
Lexus Mechanic: Victor, ASE Certified Technician replied 1 year ago

Hi Jake.

Sounded like the battery was dead and when you jumped it, the vehicle "woke up".

Have you tried pressing the start button twice with the battery jumped?

If that doesn't work, try using the key and turn the driver's door lock to unlock twice.
