Replacement Remote for Viper Systems

The Viper 7145V is a 4-button replacement remote operating at 434MHz with a 2/66 code format. It provides one-way communication for arming, disarming, locking, unlocking, panic activation, and auxiliary output control. The remote delivers a functional range of 1500 feet. It is intended for owners of compatible Viper security systems needing a new or spare transmitter.

Verify System Compatibility Before Purchase

This remote works exclusively with Viper 350 Plus, 4105V, and Responder 350 car security systems. Confirm your specific system model matches one of these three before ordering. Programming instructions are included, but the process requires access to the vehicle and the main control module. Ensure your existing system supports 434MHz 2/66 code remotes to avoid incompatibility.

Durable Key Fob Design for Daily Use

The fob features four distinct buttons laid out for intuitive operation while driving or approaching the vehicle. Its one-way transmission design means the remote sends commands without receiving confirmation signals back from the alarm unit. The plastic housing is built to withstand regular pocket or keychain carry. The 1500-foot range supports reliable operation from inside a home or across a parking lot.

Questions about this item

What comes with the Viper 7145V remote and is anything else needed to use it?

The bundle includes the 4-button remote and programming instructions. It works with Viper 350 Plus, 4105V and Responder 350 systems, which must already be installed in the vehicle.

How do I choose the correct version of the 7145V remote for my system?

Match the 434MHz frequency and 2/66 code printed on your existing remote or listed in your system manual. This remote is only compatible with the specific Viper models named above.

What does the 1500-foot range mean for daily use of the 7145V?

The 1500-foot rating is the maximum one-way signal distance in open conditions. Real-world range will be lower due to buildings, interference and vehicle surroundings, but it allows operation from well beyond typical parking distances.
