I hate to ask but.. Did you replace the battery in the (FOB) remote ? And.. the stock alarm/Door actuator sometimes only works up to about 5 - 10 feet away from the drivers side. Some move the antenna to get a few more feet out of them. Personally I would spend $150.00 at any alarm shop and get a much better alarm with room to grow ( doors,remote start, rear door popper, widows,etc.) I hate that the OEM as same button opens and locks the doors never knowing which you did.
