I have an 07 G35 coupe AT that I bought used not too long ago. A little while after I bought it I noticed that when I get in the car and close the door. There is an external beeping sound that lasts for about 3 seconds. It will also unlock my doors if they are already locked.

Basically the car thinks I’m leaving my keys inside and that I’m not in the car (which I am in the car). This only happens when I’m getting in the car.

I’ve tried having the stealership reprogram my keys and that didn’t work. I’ve tried unplugging the battery and plugging it back with no success. I’ve spent about 2 weeks searching for an answer and haven’t found anything.

Any help is greatly appreciated! This beeping is getting super annoying and if I have to pull the fuse for that alarm I’m ok with that at this point.

Thank you!

 

I'm thinking your driver seat pressure switch failed so it doesn't know you're sitting in the seat.

 

How much would this cost to fix? Would it be easy if I did it myself?

 

Firstly, troubleshoot the problem to verify. Worry about cost AFTER you figure out what the problem is.

 

That’s what I’m having trouble figuring out. I can’t find anything online about a driver seat pressure sensor. At this point I’m ok with just pulling the fuse for that alarm.
