i took my 02 wrx to the dealership about a week and a half ago to get a fuel door cable fixed and check a loose wire under the dash. the cable was fixed and the wire turned out to be a wire from an astro start unit that was uninstalled. Ever since though, when i turn off my car it will buzz behind the steering wheel somewhere, honk and light up the dash lights, and buzz again; it also wont automatically unlock my doors when i turn the car off anymore; it will sometimes make the noises when i cycle my lights or parking lights; also when I try to unlock my doors while idling it relocks them immediately about 3 times before it will finally unlock my doors. if anybody has any ideas please help me.
