The Excalibur RS370 remote start system is not entirely plug-and-play for a 2003 Chevy Trailblazer LT 4x4. While it can be installed, you will need additional components and wiring to integrate it properly.
Installation Considerations:-
Bypass Module Required
- Your 2003 Chevy Trailblazer has a Passlock II immobilizer, meaning you’ll need a bypass module to allow remote start.
- Compatible options include:
- OLBLADE-AL64 (Omega)
- Fortin EVO-ALL
- iDatalink ADS-ALCA
- Directed 556UW
-
Wiring Required
- The RS370 is not a direct plug-and-play system for your Trailblazer. You will need to connect wires to ignition, starter, and accessory circuits.
- A T-harness is not available for this model, so installation will involve manual wiring.
-
Door Lock Integration
- If you want keyless entry along with remote start, you will need to wire the system into the factory door lock and unlock circuits.
-
Programming the Bypass Module
- If you are using a bypass module like the Fortin EVO-ALL or Omega OLBLADE-AL64, it needs to be flashed with the correct firmware and programmed to your vehicle before installation.
The RS370 will work with your 2003 Chevy Trailblazer LT 4x4, but it is NOT a plug-and-play installation. You will need: ✅ A bypass module
✅ Proper wiring connections
✅ Programming for the bypass module
