  • Buy this for peace of mind
Color: OBD
UPDATE: NOT in the instructions or the help section of the app, but onliine: Best optimum results is the unit "pointing vertical label side up". I suggest getting the extension or splitter is required. Once installed, go to an open lot and drive in a circle about 3 - 5 times. this insures the device sees at least 3 satellites for accuracy. If using the extension, check your car's orientation on the map screen. If backwards, turn the carlock around where you mounted it. Buildings, trees, reflections will cause gps readings to be off. But if you drive around, Carlock will learn where the visible satellites are. This is true of any small gps. Cellphone notification speed is dependent on proximity to a cell tower and cell traffic. YMWV. This is not an alarm but a notification and tracking system. The built in vibration sensor is hit or miss. Don't depend on it. Easy to install and setup. Very little instructions needed. But read what is there first. They say give the device at least 7 days to learn your car, where you park it, and how you drive. This is important as every vehicle is built different, handles vibration different, and moves differently. The monitored circle sizes should be smaller than the two provided. I know gps and cellular location accuracy can be off by a few feet but the circles are too large. Add a smaller third and let us decide. Get the splitter. Do not plug into the port directly. The splitter will lock onto your OBD securely and you can hide your carlock while keeping your port accessible. Zip tie or gorilla tape the Carlock to the steering wheel column (if possible), or a metal frame under the dash for better vibration transfer. Sign up for the plus plan monthly or yearly. The basic gives updates every 30 seconds. Plus is every 15 seconds. Worth the extra $2 a month. Better realtime tracking updates and displaying precise turns. For the money, it is priceless for piece of mind. If setup properly, performance is great. ... show more

  • Does NOT track your car 24/7
Color: OBD
**UPDATE** February, 2023- After writing the rather harsh review below and emailing CarLock, my device was updated and the cell network it talks to was changed. After that my CarLock has been working exactly as advertised. I have been paying for the service and will continue to do so. The system does a great job tracking my cars location and movement. It’s been spot on since the changes. If I still have one gripe, it’s the tag. That little thing is kind of hit or miss but it’s really not that big of a deal for me. It’s still in my center console but I have it turned off in the app. I’m changing my rating to 5 stars! To any buyers: If you have connection issues with your device when you first get it, give CarLock a chance to fix it remotely. It may take a few days but chances are they will get it to work. As of this update, I would buy it again and will recommend it to others. ***Below is my initial review based on my first week or so of having the device in my car*** I purchased this device based on the numerous rave reviews on YouTube. It was shipped very quickly and it was very easy to install. The first two days were impressive. It tracked my car for several trips and was spot on. That’s where the positives end. It was purchased to protect my car on a cross country trip to the west coast. After two days of no issues the problems started. First I left my work and it tracked me for about a block and a half then just stopped. According to the app my car was sitting two blocks from my work while I’m staring at it in my driveway 30 miles from work. No amount of app shut down, phone reboot tricks worked. My car was two block from work. Getting more and more frustrated I drove the car around the block to see if it would unstick itself but no luck. Finally I took the device apart and removed and reinserted the SIM card. That seemed to unstick it. Next morning we leave on our trip. We’ll…you guessed it. It only tracked the car for the first sections of our trip. After each stop it seemed to catch up but then would only track for part of the drive. I’m so frustrated!!! As I write this, I’m in my hotel room LOOKING at my car out the window but according to CarLock it’s parked on the highway around 120 miles away. Already pulled and reinserted the sim to no luck. As far as customer service…NO PHONE NUMBER AT ALL. Only way to contact them is via email. You can bet I sent an email and the response was automated with some mechanic link that did not remotely help and that I would hear back from a rep within 24hrs but weekend and holidays are excluded. Guess what…it’s Saturday today. Right now I’m sooooo done with this piece of junk. I’m willing to give them a chance to fix my issues but it better be a solid fix. Final thought. Awesome idea. Does not work at all for me. Buyer beware. ... show more

  • Great GPS tracking device, with some downsides.
Color: OBD
The CarLock works very well for the price of the unit and the subscription that is monthly. I love the app that is used because it is super intuitive and informative. I like that it shows how many miles I've put on, the driving time, how many trips I've made, and the average and top speed throughout the month. There are also many notification settings that make it easy to manage what you want to be notified about, my favorite being the timer lock that automatically turns on after 5 minutes after the car is shut off. The GPS tracking is pretty accurate which works for me. The only downside in my opinion is it does take a few minutes for the CarLock to notify you when it is locked and the car starts. For example, I always auto-start my car before driving and the notification sometimes does take about a minute or two to notify me that the car has been started, this only happens a minority of the time but should be mentioned. Also I have accidentally kicked the CarLock unit out of the OBD and it was late to notify me. All in all, the system works relatively well for the price that it costs. I would definitely recommend if you need a GPS tracking system that is a good price and relatively accurate. ... show more

  • Reliable, accurate, affordable
Color: OBD
When I began to upgrade my cars equipment and drive train I searched for security and this has been the answer!! ●Had no idea it would be so accurate and well built. ● Ease of use, Installer friendly, price points in hardware and subscription are unbeatable Compared to the complicated and nightmare of others like viper. Very satisfied with software! Very sharp & user friendly, quickly updates and the sensors are so accurate!!! If It last many more months this will be my to go for security!!! Will update soon ... show more
