Our take on the Xpresskit 1101T Universal Bypass

by Gabrielle Thorndyke
Viper

Xpresskit modules work with your vehicle's anti-theft system to incorporate the convenience, security and luxury features of your Python™ alarm system.

Universal bypass modules work with any vehicle that uses an "immobilizer" key system, allowing you to remote start your car without disrupting factory-installed anti-theft features.

Use the 1101t bypass in vehicles equipped with proximity RFID or "Push to Start" Smart Key ignition systems, such as those found in many 2007-up Lexus, Mazda, Infiniti and Toyota SUV and luxury-class vehicles.

Important Note: One of your car's proximity keys will be permanently installed in the 1101T module. You can buy an extra key through your dealer and have it programmed to work with your car's immobilizer. Ask your dealer if keys can be programmed individually — some vehicle manufacturers require that all keys be reprogrammed at one time.

Highlights:

  • universal bypass for Python alarm systems
  • compatible with any hands-free "Push-to-Start" or "Smart Key" systems
  • temporarily overrides the factory immobilizer
  • maintains integrity of factory anti-theft system
  • supplied harnesses splice into factory wiring
  • includes jumper for key battery voltage matching
  • built-in circuit battery adapter
  • requires permanent key mount (into module)
  • warranty: 1 year
  • Our 60-day money-back guarantee

Important: If you know how to use a multimeter and have experience working with your vehicle's electrical system, you should be able to install this car security equipment. If you're unfamiliar with installing car security equipment, please speak to an Advisor before attempting this installation.

Features

Overview: The 1101T interface is used when installing remote start products (sold separately) in vehicles equipped with a proximity key. This type of key does not need to be inserted into the ignition to start (generally associated with push-button start vehicles). A small chip imbedded in the ignition key, called a transponder, transmits a very low powered RF (radio frequency) signal, which is picked up by the immobilizer's transceiver. Once the correct signal is received the immobilizer will enable the ignition and/or fuel systems. If an attempt is made to start the vehicle and the transceiver does not receive a valid code, the ignition and sometimes the fuel systems are disabled. The immobilizer system will then render the remote start useless. The 1101T bypasses the immobilizer  system only while the remote start is in use, maintaining the factory system's integrity. When the remote start system is not in used, the factory immobilizer remains fully functional.

Installation: The 1101T requires an active key from your vehicle to be installed inside the bypass interface module. The 1101T is then mounted underneath your vehicle's steering column. The 1101T bypass interface module features the following connections.

  • 6-Pin Harness: Wire colors include
    • Violet: positive starter input
    • Violet/Black: negative starter input
    • Black: chassis ground
    • Blue: status output from remote start
    • Red: +12 volt constant
