• 3 Channel 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 works, you should probably learn that before attempting to install this yourself. The product itself works great and the installation manual tells you everything they could be expected to tell you, given that they can't give installation instructions for every car on the road.

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 system your car has. That last part is extremely important, as it won't do you much good to hook this thing up the wrong way.

Now, on to the product. The first thing that struck me about this system is that the wiring harness included is 2 gauges larger than the harness I had before. That's nice, it put me at ease. It also includes fuses for the circuits that need them, which spares you some grief.

The head unit (for lack of a better term) is very solidly built. It doesn't rattle around like some of the others I've installed, and it has a good weight to it.

Feature-wise, this is the best deal on the market. Period. You get two accessory channels, a ground-when-armed (read: starter kill, with one additional relay) output, horn honk, dome light supervision, parking light flash...all with built-in relays (trust me, it matters.

Everything works as advertised, which is more than I can say for the other unit (BS 1702) I tried to install. 5 head units later I took the thing back for a full refund and got this.

The range is about what you'd expect, if you keep the antenna wire fairly straight and secured. I'm going to try to extend the antenna for a better range, as I'm only getting around 25 feet at the moment. Of course, that's about what I'd expect from a unit this inexpensive. If you want a really high range, spend the extra money.

The downside? It does not include the blue status LED. Considering how easy it was to find that part locally, I'm not going to complain.

I'm reasonably handy with auto repair, maintenance, electricity/electronics, etc. It took me about 5-6 hours to completely install this unit to add remote keyless entry to my 1995 Ford Mustang GT. Identifying and locating the wires is a chore. My only regret is not spending a little more $$ and time to add remote start, maybe 3-4 more wires. The remote range is fine, like the flashing blue led.

Shipped immediately to me, this keyless entry system is worth way more than I paid. Very good quality. Excellent customer service as well. Excellent Value and Product

One star reviews of this product are unfounded. This is clearly a system which requires professional installation not "weekend wanna be's". The included information says that it's for professional installation. Giving it a one star review because someone can't install it has no bearing on the actual product and system.

That being said, I bought this at Best Buy and had the Geek Squad install it. I have a 2010 Toyota Corolla. Hard to believe it didn't have one that came with it. The Geek Squad installed it without any problems -because they are professionals. It allows for one push of the button unlocks the drivers side door and two pushes unlocks all doors. That is a desirable feature since it's much safer. It has a bright blue LED light in the dash which illuminates the car and makes it look like it has an alarm. It has a good range and I'm quite satisfied. I never understand why people want to be 200 feet from their car to unlock it. That's not safe either. The fobs are nice and are the perfect size. This system does everything it says and it does it quite well. If your vehicle doesn't have keyless entry this is the best investment you can make.
