Turn the key & try to start, leave in start position for 10 minutes or til security light quits blinking, turn key to off position for 10 seconds & try to start again. Again, leave in start position til security light quits blinking, 10 minutes, turn key to off position for 10 seconds, repeat this for a 3rd time, after turning key to off position for 10 seconds, it'll fire rite up! Amazing! So happy it worked!!!!

I dont know if I should get a new key cut as I have seen this might help if it is a wore out key (5 year old key.... good chance of it) or just go buy a new sensor and put it in.....

every time i read one of theses stories i think how 10 min could be life or death. would gm be responsible.
you know, a lady stuck in a parking lot, a guy outside with a pipe,,,,,

Keys get worn, lock cylinders wear, people have too much junk hanging off of their key chains, etc. Why would a manufacturer be responsible for a wear item past warranty?

Default But is Passlock the root cause?

In Nov 18 I purchased a low-mileage 07 H3 base for my boys to drive, they’ll be 15 and 16 in February. The car was clean, still smelled new inside and only had 34,XXX miles on it.

I hit the forums since it was a used car as-is no warranty. I read through everyone’s horror stories and decided on a bypass system. I installed the bypass module and have not had an issue with the car starting since.

There have been other signs though. Every now and then I get a message to service the TPMS system and at the same time the compass in the rear view mirror goes dim and is barely legible.

I have a plug-in module so I can read and reset codes. It always says my left front sensor has gone bad. But then the next time I start the car the alarm is gone. I’m going to review the prints some more and see where the compass is powered from. There might be a ground in the wiring somewhere causing things to freak out a bit. I’ll keep you all posted on what I find.
