Alarm system

After losing my keys, I had the dealer make new keys from vin. I then accidentally tripped the theft deterrent alarm, only to discover the round door key did not turn either door's lock! I can't drive my car until I can get it to "shut up, " Can I temporarily unplug the horns, or will driving it initiate a shut down? Expense is a critical factor just now. Can't donate until my paycheck posts in about 4 days. Thanks very much. BC
