Alarm problems

Hello. Long time listener, first time caller.

I've got an '02 boxster S. The alarm recently started acting up. I can lock the car just fine, but the alarm doesn't activate correctly. The horn doesn't honk during arming, but two red LEDs flash about ten times on the dash. When I unlock the car it beeps twice. While I'm driving the car, the doors stay locked and I'm not able to unlock them with the dash buttom. If I hit the unlock button while driving, the car beeps twice at me. I have no idea what's going on. There's no moisture near the alarm control box and all indications are that my sensors are okay.

You need fault codes for alarm issues ( alarm horn beeps twice ). PIWIS or similar tool is necessary to read out.

Hi

My Boxster does a similar thing and my Durametric tester tells me there is a lock problem drivers side and the interior sensor is not working.

So I think 2 beeps means that one of the devices that ensures that the car is ready to be armed is not working i.e. luggage lids. doors, glove box and hood.

Time for U2 to check the door micro switches?

I've seen 2 cases thay were related to this. Alarm was tripping like this so we end up replacing the micro switch.
