GM keyless entry not working: HHR w/F90BT - coincidence?

Posted Jun 29, 2009 · 00:51 UTC#1

I have a 2008 Chevy HHR and installed an F90BT, perfect with all options; HD, XM, IPOD. Well, now my key fob won't work to lock/unlock, remote start or 'panic'. Coincidence or is there something I forgot? Thanks in advance for anyone's input.

Its not a coincidence...its a known problem with GM Alpha and Kappa-platform cars. The same thing happens on my Solstice GXP.

Here's a link to a repair:

Haven't had that problem with my 2008 HHR SS. I installed the F90BT myself

Hey norcalmike,

did you use the interface module for OnStar too? Maybe it really was just a coincidence. I'll go to the dealer now

yes and my Onstar worked fine before I let it lapse this month. Was just annoying because the Onstar would turn the radio off and you had to wait for it to boot up again when you were done.
