What I really liked was how I could change the sensitivity. I moved near Disneyland the fireworks kept setting off the alarm. I went to the dealer and they showed me how to reduce the sensitivity, and now I sleep all night lol. Def recommend. ### 1/5 — Did not meet the quality standards that were claimed *2023-05-02, version 2.20* I found the Krr Bt security system to be overpriced and outdated, making it a useless addition to my security setup. The accompanying app for the security product was also outdated and ineffective. I won't go into the specific issues that other reviews have mentioned. Additionally, despite some dealerships claiming that this security system could save you money on car insurance costs, it's important to note that this is not always the case. ### 1/5 — Doesn’t connect with Bluetooth on iPhone 14 *2023-04-20, version 2.20* I get a “Attention…Bluetooth is necessary to interact with the security systems. Please switch on your phone’s Bluetooth before continuing”. My Bluetooth is on, I have restarted my phone, bounced the Bluetooth on my phone multiple times, and cannot get past the initial login. Thank you KARR BT for this piece of junk. ### 2/5 — Glitch? *2023-04-19* The app has logged me out completely and when I tried to log back in, it did not recognize my email … it says it’s an incorrect email, but that is in fact the email I used when I purchased my vehicle and the email they used when I was given a temporary password for the app! Not sure what to do… other than call customer service although this should not be an issue to begin with ### 2/5 — Glitchy Show Violations Tab *2023-03-15* This KARR system was installed on all of the cars at the Honda dealership here in Pasadena, CA. On day 2 after buying my new car, someone tried to steal my tires and my car alarm went off and scared the thieves away. Yay! It was neat because in the “Show Violations” tab of the app, it accurately showed the time of the incident. However, when reflecting back upon the “Show Violations” tab, the time has adjusted every single time I look at the tab, so the time of the incident is no longer the correct time. This is concerning to me because I have about 4 other violations under this tab, but the time keeps changing every day that I look at it, so I cannot correctly locate where I was at the time of these said “violations”. Would prefer for an accurate reading because otherwise this part of the app is useless. I’m also bummed out because since it is a Bluetooth app, it only works when you are close to your car. So if someone is trying to steal something from your car, and you aren’t near it, the app will not tell you this is happing. The car alarm should go off, but when you are parked and at church, grocery shopping, running errands, you don’t necessarily hear the car alarm go off until you see the aftermath of what the thieves stole. This being said, the app needs a lot of work. The car alarm going off I am super grateful for, but the app itself needs a lot of improvement. ### 1/5 — I would be lived too! *2023-02-10* It’s a passive system, with tech now a days you can do stuff way cheaper and much simpler! Apple tiles for example would easily replace those gps viper systems which where great when they came out! Just like anything else people want to ba able to control every part of the system good or bad?!?!? This system is dealer installed so it’s just about profit for the dealer ship. Hey we are running a special on alarm system this week, also I can save you a lot of money with that and our undercoating! We can work it right it to the payments, every hundred or so adds 15 or more to the payment. They are smooth and touchy feely car’s salesmen. ### 1/5 — False sales DO NOT WASTE YOUR MONEY!!! *2022-12-06* All this app does is replace your factory key fob and is more inconvenient to use since you have to open the app, log in, select your vehicle, then wait for it to connect to lock or unlock it. I can do that with my key fob in my pocket. I was sold on the idea that I could see where my car was if it was stolen. NO YOU CAN’T. You can ONLY see where your car was when you locked it last WITH the app. Right now I’ve used the app 6 times today and it’s still showing where my car WAS 2 days ago. DO NOT WASTE YIUR MONEY!!!! ### 2/5 — Does not connect *2022-10-17, version 2.20* Garbage ### 4/5 — Great useful app, room for improvement *2022-10-07, version 2.20* Very reliable, wish we could open and close at a farther distance. Also would be great if the developers added hands free option to open on proximity detection without having to even open up the app! ### 1/5 — App is slow and outdated *2022-08-25, version 2.20* The app does not work as fast. Very slow and the UI is clearly outdated. Please update it to 2022 standards. Thank you. Also allow for an unlock and lock widget for our home screens so we don’t have to always open the app. Maybe a siri shortcut would be great too. ## Frequently asked questions about KARR BT ### What can I do with this app?
