Service keyless start system

Bandit · Aug 14, 2014

So, I loaded up my car with my important stuff in preparation for a move in 36 hours, imagine my excitement when I went to get back in and discovered an issue!

I couldn't unlock the doors with the buttons on the door handles. I used the remote to unlock, got in and started it as normal, by just pressing the button while pressing the brakes. The dash then displays "Service keyless start system"

Well, the keyless start system is working fine, it is only the unlocking doors or trunk that is not working. It does work with the trunk if the doors are already unlocked though and the wireless remote works fine to unlock, I do not need ot use the keys. Any ideas at what I could troubleshoot? I can't try my second keyfob as it is packed in a box right now and I have no clue which box! LOL

Thanks!

p.s. I did search and read a few threads before posting, none were identical to my issue that I found.

There is something blocking the antenna in the trunk floor. I had the same issue about a year ago on my ltz the keyless sensor is located towards the front middle of the trunk floor. Once you unload you should be fine.

I love you and makes perfect sense, especially since all my important stuff I loaded in my car instead of uhaul are desktops and servers. Thanks!

Keyless System Start Up

My car keeps popping up with a system icon saying that it needs to be looked at what would that mean?? Is it something I can fix on my own? Or take to the dealership?

If it isn't all the stuff you put in the trunk, I would consider replacing the FOB battery, but if the antenna is in the trunk..... I would listen to what these other guys are saying.

Did unloading the trunk fix the problem? I installed a big subwoofer box and have had the "keyless start system" light on since. Im about to take all the equipment out to test, but wondering if this fixed your issue before I start because its a hige task
