Overview
Not a two-way system that reports back to the remote, the Viper 3103V is a one-way alarm that sends commands to the car. The kit includes the alarm brain, two remote controls and a siren, with an impact sensor and starter interrupt.
Keyless entry, a loud multi-tone siren and engine disable protection give an older or basic vehicle a security upgrade. The long warranty on the brain is a plus. The limitation is the one-way link: the remote cannot confirm that the alarm actually armed or triggered.
Who it's for
Daily drivers and older vehicles without a factory alarm are the typical installs. Owners who want status feedback on the remote, or who are not ready for professional installation, should look at two-way kits or installed options.
Pros and cons
- Loud siren with several tones
- Long range for a one-way remote
- Lifetime warranty on the alarm brain
- One-way remote gives no status feedback
- Installation parts not listed
- Remote warranty shorter than brain
Performance notes
The alarm brain watches the impact sensor and triggers the siren when it detects a hit. The starter interrupt blocks the engine from starting, so a thief who gets in still cannot drive away. The remote range depends on obstacles and interference, and the listed distance is a maximum.
