Setup and Installation
Installation of this remote start and keyless entry system requires technical knowledge of vehicle wiring and electronics. It is recommended that installation be performed by a qualified professional. If you choose to install it yourself, proceed with caution and ensure all safety measures are followed.
General Installation Steps:
- Preparation: Disconnect the vehicle's battery before starting any wiring. Gather all necessary tools.
- Access Vehicle Wiring: Carefully remove necessary dashboard panels and trim to access the vehicle's ignition, power, and other relevant wiring harnesses. A trim removal tool (like the one pictured below) can be helpful.
- Module Placement: Mount the remote start module and bypass module in a secure, hidden location within the vehicle's dashboard, away from moving parts or excessive heat.
- Wiring Connections: Follow the detailed wiring diagram provided with your kit. Connect the remote start module to the vehicle's ignition, power, ground, door locks, and other necessary circuits. Ensure all connections are secure and properly insulated.
- Bypass Module Programming: The bypass module will need to be programmed to your vehicle's immobilizer system. Refer to the specific instructions provided with the bypass module for this critical step.
- Remote Programming: Program the included 5-button remotes to the remote start system.
- Testing: Reconnect the vehicle's battery. Test all functions of the remote start and keyless entry system thoroughly before reassembling the vehicle's interior.
- Reassembly: Carefully reassemble all removed panels and trim.

Operating Instructions
Your MPC remote start system comes with two 5-button remote controls. These remotes provide long-range operation for starting your vehicle and controlling the keyless entry functions.

Image Description: Two identical 5-button remote controls, each with a metallic key ring and clip. The buttons are typically for lock, unlock, remote start, trunk release, and panic/auxiliary functions.
Remote Control Functions:
- Remote Start: Press the remote start button (often indicated by a circular arrow or "START" icon) twice within 3 seconds to start your vehicle. The vehicle will run for a preset duration (e.g., 15 minutes) and then shut off, or until you enter the vehicle and turn the key to the ON position.
- Remote Stop: To turn off the vehicle after a remote start, press the remote start button twice again.
- Lock: Press the lock button (often a closed padlock icon) once to lock all vehicle doors.
- Unlock: Press the unlock button (often an open padlock icon) once to unlock the driver's door, or twice to unlock all doors (may vary by vehicle and programming).
- Trunk Release: Press and hold the trunk release button (often a trunk icon) for approximately 3 seconds to open the vehicle's trunk.
- Panic/Car Finder: Press the panic button (often a horn icon or "PANIC") to activate the vehicle's alarm and horn. This can also be used to locate your vehicle in a crowded parking lot.
Note: Specific button assignments and advanced features may vary slightly based on the exact model and programming. Refer to the detailed programming guide for your specific system.

Maintenance
The MPC Remote Start/Keyless Entry Kit is designed for reliable operation with minimal maintenance. However, periodic checks and proper care will ensure its longevity.
Remote Control Battery Replacement:
- If the range of your remote control decreases significantly or the LED indicator (if present) does not light up, the battery may need replacement.
- Refer to the specific remote control model for battery type (e.g., CR2032 coin cell).
- Carefully open the remote control casing using a small flat-head screwdriver or a pry tool.
- Remove the old battery and insert the new battery, ensuring correct polarity (+/-).
- Snap the remote control casing back together.
System Care:
- Keep the remote controls dry and avoid exposure to extreme temperatures.
- Do not attempt to open or repair the main control module or bypass module yourself, as this may void the warranty.
- Ensure all wiring connections remain secure. If you suspect a loose connection, consult a professional installer.
