issue with car, any help?
 

As I pulled up to work and turned the car off the parking lights and door chime would keep blinking in 3 second intervals. THe security light was NOT flashing. I thought this was VAT system so I got outta car and started and stopped car several times and still did same thing. THere is an aftermarket alarm but it was functioning as normal. I just unplugged my battery. ANy ideas? Thanks ahead of time
