I NEVER leave my car unattended with the top down - I learned the hard way! In a matter of minutes my K40 was "removed" from my glove compartment along with my mobile phone charger (ha, ha, they thought the coiled cord belonged to the K40 which was hard wired). All this with my "red clip" in place..........

The "little red clip" clips into the latch when the top is down and "fools" the car's alarm system into thinking that the top up so that the interior alarm is able to be armed when the top is down. It's available through your Porsche parts department.

don't the 987 models have a redesign that makes the alarm fxn when the top is down, therefore, bypassing the need for the red clip?

I am new to this also. Is the red clip code for activated alarm?

It seems that there are some options available on lesser roadsters to prevent encroachment, or at least punish it.
