Add-On Security Upgrade with Siren for OEM Keyless Entry Systems

The CS-884S.OEM is an add-on security system designed for the purpose of upgrading your factory keyless entry system to a full-blown security system. Desinged for use with newer vehicles 2007 and up, this upgrade system requires a data module so it can see the lock and lock commands come from the OEM remote control and effectively arm and disarm the security system as you please. The system also comes with a dual-stage shock sensor to pick up vibration around the vehicle when the system is armed and a 120W sigle tone siren to alert you when the alarm is triggered.
