ScyTek Astra A4.2W

Awesome Bang for your Buck

This product is pretty simple. Me taking my time, no rush, and first time ever installing remote start it took me 5 hours. Everything works, keyless entry, remote start, the door sensor and shock sensor and trunk release. Still debating if i want the the hood pin installed. But the remote start feature, when you read the manual on how to program the system to remote time and long siren, the different branch modes thats adjustable. The system can learn the true RPM time so it can start the car everytime the first time. My car starts the first time even when it's extremley cold. The tru rpm tech mode allows it to do that which is great. The horn/siren is loud when it goes off. All 2 way pagers has a delayed reaction when the alarm goes off and you want to shut it off because it first sends the pager a signal on what cause the alarm to go off. But the single pager is instant. Oh, the 2 way pager can be programmed to automatically start your car at a program timed every day. That's a great feature. And it shows a timer for how long the car has been running. I tested this pager to remote start in the city to easily remote star at 1/4 mile measured distance. This alarm is loud. And an added feature is you can set from the antenna inside the car to turn of the alarm with a code if you need to get in the car without the keypad. The key is to make sure you learn how to enter the program branch mode so you can make the alarm learn the cars TACH. the tach/rpm wire is normally on if the wires plugged into the coil pack where your spark plugs are. The car learns the real time rpm in 1 second! So you don't have to worry about it killing your starter. It will start it better than you, trust me. Maybe i'll post a video review if someone wants to learn how to program the system to customize it. Install the shock sensor where it's easy to get to because you can dial in the sensitivity! that's all i can think of.

Awesome Product

This alarm is great...not only is the price reasonable but the product is unbeatable. Hands down the best alarm on the market...

good product.

I recommend your product to my friends because it's very helpful. Two of my cars have your alarm with the option to start with my remote control. I live in Seattle where most early morning and night were cold. So before you get in to your car it's been warm and ready to roll.

Great Value

It works great, good distance. The install was a little challenging. The instructions were good for the unit, however, spent some time researching my vehicle's wiring diagrams. Will need to purchase relays, they don't mention that .

great price, excellent unit

Works great, have installed dozens of these in the past year, have not had any problems, very easy installation compared to other brands, the tachless mode works perfect every time. No need to waste time hunting for the tach wire. And excellent price.

Got the job done at the right price

My first install of a car alarm and starter. It worked great right out of the box. Easy to setup and get used to.

Only Con I found is that the two remote eats up batteries and the battery cover broke after the 2nd time of taking it off.

installed on 2000 honda Odyssey

This system works great. Only complaint is the life of the 2 way remote battery, 1 AAA seems to die often. using bypass module to simulate key in ignition. Installed myself but it can be tough to do.

excelent products from the scytek/astra co.

easy install, work all the time never had any problem with anything from scytek. been an installer for ten years, also the range on their remote starts is flawless.

This Alarm is GOOD.

I hav been using these Scytek alarm systems for the past 6 years and has had no trouble of problems other than, I damaged the LCD on the remote by sitting on it.
I had 6 different modles installed in my vehicles and NEVER had a problem, other than the LCD damage on the remote.

I will like to let any body who has second thoughts of purchasing a ScyTek alarm system, to go BRAVE & BUY.
