AFTER PROGRAMMING REMOTE FOBS NOW HAVE PROBLEMS WITH ALARM FOB, WINDOWS AND LIGHTS

2003 Hyundai Sonata • 98,000 miles

03 Hyundai Sonata GLS V6 97700 miles (Purchased 4/3/12 - now 5/20/12)
Unmounted alarm module to program second remote fob and reprogram original fob. Checked for operation of all 3 buttons on each remote, everything fine. 2-3 days later lock button on both remotes stopped functioning, 2-3 days after that, unlock
buttons on both remotes stopped functioning. Trunk release on both remotes are still
working.
About a week after programming remotes, noticed power windows stopped working. Then noticed dash lights, tail lights, dome light (only on door function) and fog lights stopped working. But all, except door function of dome light would work
when either front door was open, but stop working when door was closed. Now, whether door is open or closed, none of these items are working. Have checked fuses but found none burnt out, rechecked alarm module, it seems secure. Tried
disconnecting battery for 30 minutes, no change. Any help would be appreciated.

Sounds like a bcm issue. You need a shop with a scan tool to monitor what is going on. It may be a failed bcm
