Security & Remote Start Accessories

Our security and remote-start accessories help installers add, replace or integrate components in an existing vehicle system. They suit drivers and shops handling a lost transmitter, a security upgrade, or an installation that needs added connectivity or backup power. Match each part to the alarm or remote-start model and its connector.

Match Accessories to the Installed System

Start with the system's make and model, then compare the replacement part number and plug style. Brand alone does not guarantee compatibility. A replacement transmitter must pair with the specific system, while an integration module must communicate with both the vehicle and the remote-start or alarm unit. The Viper D9147V transmitter kit is a replacement accessory, not a complete alarm or remote-start system. Review programming requirements and plan for pairing during installation.

Choose the Function Your Installation Needs

Accessories handle different jobs. The Directed DSM550 SmartStart PRO Smartphone Module adds smartphone connectivity to a compatible system. A backup battery, such as the Directed 520T, supports the security system if vehicle power is interrupted. For added detection, the VOXX DUB1 Digital Tilt Sensor senses vehicle tilt. The Viper DS4SU Security Upgrade Kit combines a siren, shock and tilt components for a security upgrade.

• Replacement: Match the model and part number, then confirm pairing needs.
• Integration: Match the interface to the vehicle and the remote-start system.
• Added protection: Decide which sensor or backup function the system needs.
• Installation: Follow the wiring diagram and protect connections from vibration and moisture.

Plan Wiring and Programming Before Installation

Do not treat an accessory as a complete system. Check that the existing alarm or remote-start unit has the connection and support the accessory requires. Route wiring away from moving parts, sharp edges and heat. Secure modules so they cannot rattle, and test each feature after installation. If a part requires programming, complete that step before handing the vehicle back.

For a complete setup, compare these accessories with our remote start systems and remote start and alarm systems. For added protection without remote start, see our vehicle security products.
