Viper 211HV 1-Way Keyless Entry System

I agree with the previous poster that the one-star reviews are unfounded. Anyone purchasing this product must know that they will end up soldering wires under their dash. How else would you expect this box to open your doors and blink your lights? Come on...

As for the product, it works exactly as described and as one would think it should. For $50, this is a bargain. It took me about 3 hours to get it all installed and a good deal of that was figuring out which wires did what in my car (a manual will bring this time way down). That said, the installation couldn't be easier once you know which wires you want: just strip off some insulation, solder the appropriate wire from the harness provided to the wire in your car, repeat as needed. Simple, simple.

Electrical circuits in cars are _very_ simple. For the most part, they're all just circuits that switch power - no signals to transmit or anything fancy. That said, if you don't know what a relay is or how one...Read more

I'm pretty technical and I have wired up remote entry in the past. But, cars are much more complex than they used to be. This was being installed in a Subaru and the documentation wasn't quite good enough to get me there. Even google couldn't find me all the correct wire locations to make the connections. I gave up and had it professionally installed. Ended up costing me the same as just going there and buying it in the first place with installation. Good product, that works well once installed. Hiqh quality remotes with about a 100 foot range. Nice.

Let me be upfront about this: I purchased this product after trying to install a similar system made by Bulldog Security. That system was slightly more expensive, but available at a local parts store.

Before buying this, be sure you know how to connect wires in your car. Also be sure you can figure out (or find a diagram) telling you which wire is which. I would think that is an obvious thing, but the negative reviews seem to be largely based on the fact that these instructions (labeled Professional Install Only) do not explain in painfully clear detail how to do everything.
They include a diagram of the harness that connects to the head unit and very clearly explain what each wire is for - which is really all you need in the first place.

That said, for the Do-It-Yourself'er with some basic auto wiring experience, this is not a complicated job. The most difficult thing will be figuring out where you'd like to mount the system, and what type of door lock...Read more
