I'm at work, and when I unlocked the door, the alarm went off. I don't
have a keychain for it (I got it used, didn't even know it had an alarm).
I'm assuming there's a chip in the key, but for some reason it isn't
being recognized (tried both regular key and valet key). If not, a
regular motion alarm just armed itself for the first time?

This is a 2001 Eclipse Spyder, btw.

So I have two questions:

1.) How can I turn this alarm off so I can drive it?
2.) How do I make it so it doesn't go off in the first place?

The manual to the car is at home. Don't wanna drive it honking and
flashing in the middle of the night. Or during the day, for that
matter. :)

Thanks in advance...
