Viper's elegant new Responder LE transceivers mark a giant leap forward in 21st century remote start, and an evolutionary milestone for the keychain remote. These slender & sophisticated 2-Way remote controls feature a clean sleek ergonomic industrial design, made to fit the user's hand comfortably, enabling effortless and intuitive single-handed operation as Brilliant LEDs confirm your commands.
I purchase this remote start and was told the installation would only take 4-5 hours. After 10 hours my car was still not completed. He explained he was having difficulties with the remote start being effected by the doors. The installer stayed after hours to complete and called to say everything is done. Within the first day the remote start was already acting up. Whenever it was running and you opened the door the engine would shut off. It now does this 90 percent of the time! Also it randomly shuts off anywhere between 1 minute after start up and 10 minutes after start up. Not knocking the product but I take it very seriously that a PROFESSIONAL should install this product!
