Remote coding, $ 100.
You need to buy a cable for connection from laptop to car. He sells these too, that's how I found him on eBay.
He gives instructions for you to download a few software programs to your laptop. Then just set up an appointment with him and he remotes into your car and does the coding in one session. It was super easy and he's a good guy. Took about 10 minutes for him to code the below items for me:
- unlock doors when car in park and turned off
- non-dazzle high beams
- Auto fold in rearview mirrors on door lock
- Increase Angel Eyes brightness to 100% with headlights on
- turn off seatbelt chimes
- transfer cell phone ring to be the ring when a call is received by the car
- Close windows and roof from key fob
- DVD use in-motion
- enable cruise control at lower speeds than factory default
- enable exterior door puddle lamps when car put in reverse
- enable brake lights to "flash" 3 times when ABS engaged, then they turn solid
