Home > Consumer Reviews > Viper 5901 Responder Two-Way Security System

I have had 5 viper products over time and this is the best one I have owned. I installed it by myself in my 2006 Jeep Grand Cherokee and it works great. This model remote has a better screen than my other car which has the 5900. The rechargeable battery is a must compared to putting a new AAA battery in every few weeks! What a waste. The range is good and combined with a CAN BUS module, install is much easier these days and integrates with the factory computer/alarm system. In fact, I can use the original unlock/lock remote and it arms/disarms the VIPER! I don't use it because I need the remote start feature but it is nice to have an additional backup. Also, the 5901 (unlike the 5900) comes with a second remote. It is the 1 way remote, but is still great to have a second remote to go with the second key. DE also put the arm light inside the antenna. At first, I didn't like this but I found a nice spot behind the rear view mirror and tucked in the roof that allows the light to shine yet be somewhat discrete. Also, the program button is on the antenna. Just make sure you can access it and don't tuck the antenna to far way! Because of these changes, you have to have the antenna plugged in for the 5901 to even turn on. I had it all hooked up and thought I'd be able to test. No worky. Turns out the antenna has to be plugged in! Good to know. The shock sensor is now built into the main box too. Not sure what I think about that yet. Last thing is the remote is awesome. I already mentioned the battery, but the remote is now a mini computer. There are so many programming options such as, more feedback about the status of the car, current time, cabin temperature (which is currently stuck at 95 deg all the time!), several color options to choose, vibrate and several audible options (5900 had some of this), and a bigger screen. All in all.. love it. This is the best out there.

I had the previous generation units on both my vehicles and when I replaced one of them I purchased this unit for it.

I'm using it on a 5spd in manual mode and it works great!

It has better battery life, smaller weight and size, and the keypress respond quicker than the last generation so I'm happy all around!

I have brought this item from US and was installed in Kuwait, I was shocked that I didn't find somebody that can install it, but, luckily, I found one, even he was expensive :), but, he have done good job.
it has a very good range, but, not much in concrete walls, I can run it from my flat in the 4th floor!!!! WOWWW.
so, nice range, very cool options plus, very stylish remote.

The price is relatively high, but, it's still new, but, again it worth it.

Had installed in '01 Chev Suburban by American TV (about $150 for installation but after installing an alarm myself years ago, not a bad price to save time and headaches - let the pro's do it). Needed to purchase Xpresskit DLPKGM module for remote start to work. Brought both items to installer and drove away a couple hours later. Be carfull where you/installer installs the hood pin sensor or alarm will go off with a slight breeze. (has happened on 2 other vehicles. I don't know why the installers just can't get this right - worked great after a slight height adjustment or relocation of sensor in both cases) 2-way remote can be charged via usb (not included) or wall charger (included). Remote shows if truck is locked, which sensor is triggered if alarm goes off (door, glass, trunk...), cabin temp, time, & much more. Remote also has vib, light, and tone alerts when alarm is triggered. Additional ports on alarm allowed for other options such as auto defroster-on in cold weather and window acutators that roll up the windows if security is breached. Add-ons require additional labor and may require additional parts but atleast the option is there is you are interested. Over all very happy with setup.

Just got the alarm installed 2 days ago, but I think its great. The Screen gives you all the info that youn need and tells you that the car is locked or unlocked at all times. I also like that the remote is a rechargeable battery via mini USB! I find it to be an awesome feature. A liittle thing that I also like is that it displays the time as well. Only thing is that i need to make it a little bit more sensitive, but i have to bring it back to the shop for that. Highly Recommend!
