...is it the stock alarm system or is an aftermarket one...? if its the factory one i'd say buy a new keyless entry remote from somewhere and ask the dealer how u can reprogram the thing to work for ur car...?

 

im not sure if its aftermarket or not...but i did buy another remote off ebay but the directions said you have to have a already programmed remote...i dont know if you need to have the same thing if i take it to the dealer or not?

 

Just ask the dealer for help. Is there a name on the horn of the alarm under the hood? (You know the part where the sound comes from when you trigger the alarm). You need a name of the alarm and model number then you can contact that company and also see if it is a factory or aftermarket alarm.
