try hitting both the unlock and lock buttens at the sametime and that should reset the alarm on it if that dont work than you have a prob. with the system and should bring it back to the dealer and thay should fix it

ok heres what you do......
1 remove the positive cable from the battery.
2 let it sit for about 10 - 15 minutes
3 reconnect the battery

this should work.
