Viper Directed Universal Bypass

Some vehicles absolutely need the key or fob to be in close proximity to the ignition switch in order to start. This transponder key uses a radio-frequency signal to disarm the vehicle's immobilizer, so you can start it. Directed's 556UXL bypass module provides a clever work-around, so you can add a remote start system that'll work in such a vehicle. You will need to permanently install one of your vehicle's keys inside the 556UXL module. (The 556UXL is a larger version of the 556UW, designed to handle larger keys.) If you need that spare key, you can buy one 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. 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 bypass module yourself. If not, please consider having your system professionally installed...
