Trunk Unlock Not working

tpo209 · 10-09-2021, 10:06 AM

I've searched but haven't found anyone with this issue. Hopefully someone can help.

I used to be able to walk up to the trunk with they key in my pocket and the trunk would unlock so I could open it. Essentially the same way it works on the front doors. Now, the front doors still unlock when I walk up to them but the trunk does not. Is there a sensor back there that senses the key thats broken? I admittedly haven't tried replacing the fob battery but both fobs still work on the front doors so cant imagine thats the problem.

Thanks.

Yes, there is an extra antenna / sensor for this function, which is located in the trunk under the cover near the fuse box.

Thanks. Any idea on a part number, how hard it is to replace?
