Car is an AP1 (my00), 34k miles

So out of the blue my alarm & key fob just stops working. I've done quite a few searches but havent found any answers that describe all the problems I'm having.

3 Days ago everything was working fine. I went to the store one day, locked my car w/ the remote, and when I got back the remote wouldnt lock, unlock or open the trunk. When I first got my S I used to have this problem maybe once a month but it's been about 6 months since it happened (used to take a few minutes of button pressing before it would work) and now it's been a few days and still hasnt worked.

Problems:
-When everything was working, after keys were removed from ignition and door was opened and then closed, the alarm as automatically turned on & doors would lock after a few moments
-This doesnt happen anymore now that the remote doesnt work
-No alarm, no automatic locking etc
-I have 2 key fobs, neither work, replaced both with new batteries and still neither work (but red light does appear so obviously they're not dead)
-Read a few "remote reprogramming" threads which I followed and still the remote doesn't work
-The alarm used to sound (i think??? I don't really understand how these alarms worked, they seem to go off randomly) if I tried to open a locked door latch several times but this doesnt happen anymore.
-I don't think that the door locks themselves are dead because the trunk doesnt open either and the car doesnt beep if you try to lock it while a door or trunk is open.

Only thing I can think of is a fuse somewhere. Any help??

Thanks

Might be better to put this in the electronics subforum. I was going to recommend you look at the fuses. Is this an OEM alarm or aftermarket one? Did you get the alarm installed or was it bought that way? Sounds like there is something wrong with the alarm system which is causing your issue.

 

Ever figure this out? My oem remotes stopped working out of no where as well as my trunk release inside the car. Strangely enough my aftermarket alarm remotes and keyless entry including the trunk release function work there.

 

Fuse 26 provides power to both the keyless module and the glove box trunk switch.

MARC - your after-market alarm may provide power to the locks and trunk from a separate power source so maybe that's why they work.

 

its probably the little valet switch by your left knee

 

Thanks for the heads up Modifry. That's exactly what it was. Apparently there's a short somewhere that blew the fuse (and blew a second one I put in). I thought I had checked it before but I think I was reading the fuse panel map upside down (doh!) so I missed it the first time.
