ok i need help my autostarter isnt working on my g6 when i try to use my remote to start my car the lights flash 3 times does anyone know how to fix this or why this is doing this

is the check engine light on?

If it is a factory system, you need to click the lock button first and then immediately click and hold the autostart button (arrow going in a circle) for about 3-4 seconds and then it will start- the 3 blinks is to let you know it "heard" you but can't execute the command. you will get that same 3 blink light if you cycle the autostart twice without putting a key in the ignition (cycle=start, let run for 10 min., car shuts off)- if that happens, go out and start it manually and it will restart the 2 autostart rule. you may also want to check in your info center to make sure the autostart feature didn't get accidentally turned off.

yup. that's what you do!

My factory automatic start doesn't work, the menu states its on but the lights only blink once. no check engine light went on at all.

It's the hood latch. There is a way to bypass it. :)

Lol does your car honk also?you might be pushing the alarm button.

Yes hit door lock then hold down start button for 3 seconds. Dormain replacement keyless Entry Remote work for my pontiac G6 Gtp. AutoZone or Amzon has them they are replacement for GM products.

Any other troubleshooting tips?

Sorry for additional. I was able to get mine to work once but just beeps horn 3 times now. No codes, engine lights, door/hood open... I’ve read it can be bad fob?

Does hood latch sensor, if faulty, throw any code or engine light?

Anyone know bypass hood latch issue?

There should be 2 wired going to the sensor, they just need to be cut and wire nut them together to complete the circuit bypassing the sensor itself. Worked on my 05 g6.
