Vehicle Security

(62 products)

Our vehicle security systems are for drivers adding an alarm, remote start, keyless entry or replacement parts. The right setup depends on your vehicle, transmission and the functions you want. We help you match the control system with the interfaces and wiring needed for the installation.

Choose alarm, remote start or both

A basic alarm focuses on alerts and protection, while a remote-start system adds engine starting from outside the vehicle. Combined systems bring both functions together. The Avital 3103LX 1-way alarm and Avital 3308L 2-way LCD alarm give you different types of remote communication. For alarm and remote start in one system, consider the Excalibur AL-1680. The Viper 4105V combines 1-way remote start with keyless entry.

Match the interface to the vehicle

Many newer vehicles need an interface to connect an aftermarket system with factory electronics. A bypass interface can support the vehicle's immobilizer function, while a data interface can handle functions such as door locks. The Directed DB3 interface has remote-start-ready capability. Vehicle-specific T-harnesses can simplify connections, but the correct part depends on year, make and model. Transmission also matters for remote-start safety and system programming. Start with those vehicle details, then confirm the installed system's exact model when replacing a remote or antenna.

Plan the wiring and programming

Functions: Decide if you need alarm alerts, remote start, keyless entry or two-way feedback.
Compatibility: Match the system, bypass module and harness to the vehicle and transmission.
Replacement parts: Match the remote to the system model and button layout. The Prestige 145SP 5-button remote is a replacement remote, not a complete system.
Installation: Account for wiring, programming and any required interface modules. Professional installation helps prevent wiring faults and unreliable operation.

For complete systems, compare our basic vehicle alarms, remote start systems and security and remote start accessories. We can help you plan the system and supporting parts around your vehicle.
