Customer Ratings & Reviews

Works great on 2017 Honda Accord. Small remote but works fine.

Got a great deal on truck alarm. Had all the features I was looking for and the security I needed.

I bought and had the VIPER DS4+ Remote Start and the upgraded 2 way remote installed for my husbands 2006 Ford Expedition on 10/17, drove it home, ran to the store - everything working GREAT !!! On 10/19, he went to get in and run to the store, didn't use remote start, just the fob to unlock, put the key in the ignition and turned it to start the truck - NOTHING, NO CLICKING, DIDN'T EVEN TRY TO TURN OVER - but hey the radio still works (eye roll here)!! Vehicle will not start with the key now, will only start with the VIPER remote start. Taking back to Best Buy in Brentwood TN on Saturday 10/23 to have it completely removed. There is a blue light that flashes on the receiver antenna, it has been blinking the last 2 days when I went out to go to work and noticed that the blue light is no longer blinking. I don't know what is wrong but this thing is JUNK and seems to have a known issue that VIPER hasn't acknowledged! At this point I don't even know if the vehicle is drivable. Guess we will be finding out. I had a different unit put on my 2019 Toyota 4Runner, will be having that unit installed on the Expedition. I just can't trust this isn't going to shut down my husbands vehicle even if they get it running. Not worth the chance of it shutting down driving down the highway at 70mph and killing my husband. *** Will update after the removal ***

This is my second Viper system. It works great. I only wish this system came with a second remote like my older system.

I purchased this for my son’s truck. He loves the convenience of being able to control it with his call phone.

The installer was wonderful, he was flexable with his schedule.

I have this on both of my cars now and my wife and I love being able to warm up are cars before we go anywhere

This product work perfect. Love the extra security feature

Had this installed by best buy technician. Works great. I wish I could say the same about the installation service. They went an hour over time that they told me it was going to take. They do not have a waiting room there for situations like this.

Feeling secure knowing where my vehicle is at all times.

Product works very well and has great distance like I was needing

We have just recently purchased this auto start and have not really had a chance to really test in out in the rel world

Garbage I do not recommend this starter to anyone the starter messed up my security system in my car

This works great and I highly recommend it for getting your car warmed up or cooled down.

Received quick. It hasn't been installed yet.shipping was fast

purchased remote start and sat radio install , when I went to have the install done was told appointment was only for remote start and I would need to purchase a tuner for sat radio and make another appointment for install, This was a christmas present for my wife and was to be done on only day off. Salesman and followup people should have known if I was missing parts as I made sure they knew what I wanted and thought I purchased and made appointment for install of both. I was very disappointed and canceled all.

Best choice I’ve made yet. Easy start. I get in and go.The best addition to my car thus far!

Always been a fan of viper alarms, always install them in all my vehicles.

Great product to heat or cool your vehicle. Works awesome.

Enjoyed this alarm system so much it's in 3 of my vehicles
