- Reviewed in the United States on March 18, 2025Color: OBDVerified PurchaseCarlock is the most amazing device GPS locating you can locate just about anything as long as you have a OBD connection in your vehicle or toy or machinery. The design is incomparable. They have different plans for as much protection as you want but I go for the $9.99 cent standard subscription per month and believe me it is so worth it to know where your vehicle is 24/7 365 days out of the year. It's super easy to use and they have great features too. Such as notifications if you're driving too hard or driving crazy it will notify you to slow down don't break so hard. Most of all don't drive crazy you can set the miles per hour to what you're comfortable with mine set to 80 Maximum speed. That's on the freeway of course. The Carlock actually helps you not get tickets. And drive safer whoever's driving the vehicle you can monitor your kids driving your car or truck. Or if you have the mobile Carlock you can have it on a piece of your machinery and find out where it is at all times a case to get stolen such as a cement mixer I personally will always have this app no need for a LoJack You can monitor several vehicles at 1 time inside the app. I recommend this app to all of my friends and family you can't beat it and for the low low price Carlock is unbearable by any other GPS car, vehicle Or machinery Location finder I love car lock and wouldn't trade it for anythingTake my word for it it will be so worth your time and money to invest in such a small device an application for $10 fee per month subscription I love you Carlock you're the greatest!

- Reviewed in the United States on March 3, 2025Color: OBDVerified PurchaseI was in the market for getting a GPS Tracker with an alarm. I am old school, I was looking for an alarm that sounds loud and everyone can hear it. This is NEW technology, when you buy the (motion sensors ) extra. They go off as soon as the car detects any movement and the APP on your phone goes OFF LOUD. There is no excuse I did not hear the alarm. At the car there won't be any sounds. This is good because the person messing with your car will not know. Giving you time to act in which ever way you decide is safe for you.
The app gives you GPS TRACKING depending on the subscription you purchase. The subscriptions are the most reasonable on the market at this moment. It also lets you set an alarm at any top speed you want. Anyone driving the car goes over that speed the alarm will go off on the APP on your cell phone. It also rates the way you drove your trip letting you know where you were speeding and where you did hard stops. The app also shows you how many miles you have driven on a monthly basis in case you want to keep track of your milage. Trips you have taken and length in time of each trip. Many more features, I just want to give you an idea on what you will get with this unit.
As far as the Unit I purchased the OBDII extender and placed the unit away from my OBDII. No one knows I have the unit installed except me. Plus it leaves the OBDII open for any time you might need to access it. This unit also activates the alarm on a timer. The app lets you set up the time you want the unit to activate after you have turned off the car.
I purchased the unit I also purchased sensors for each door of my vehicle as well as the tag. The TAG is one of the greatest add on I highly recommend. What the tag does is activates and deactivates the alarm automatically when you come close to your car automatically. This way you won't have to do it with your cell phone before you open your car.
All in all if you want something that will not break the bank and will give you a piece of mind I will highly recommend this unit. The only thing is that in order to make this GPS ALARM work the way it is intended to don't SKIMP out on the add-ons. Buy the add ons you need because you will save on the monthly subscription and have a piece of mind. How much is a piece of mind worth it to you?
Item I would highly recommend and I am not part in any way with this company. All I am is part of the CARLOCK Family.
- Reviewed in the United States on July 9, 2024Color: OBDVerified PurchaseUPDATE:
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.

Thomas H.Reviewed in Germany on June 7, 2024
5.0 out of 5 stars Sehr zuverlässiges System für ein Top Preis-Leistungsverhältnis.
Color: OBDVerified PurchaseWir wollten zum Schutz unseres Wohnmobils ein gutes System mit einem ordentlichen Preis-Leistungsverhältnis. Nach langer Suche haben wir mit CARLOCK dieses System gefunden. Die Installation ist sehr einfach und schnell, man benötigt keine großen technischen Kentnisse oder ähnliches. Auch der Download der App war problemlos. Die App ist sehr übersichtlich und leicht zu verstehen. Direkt nach Anschluss und nach dem Anlassen des Motors hat das System sofort reagiert und entsprechende Warnungen an die App gesendet. Jetzt nach mehreren Fahrten mit dem Wohnmobil wird das System immer genauer und ist sehr hilfreich. Alles in allem eine sehr gute Investition in ein sicheres System. Zu guter letzt muss man die hervorragende Kommunikation mit dem Unternehmen hervorheben. Man wird in E-Mail Form informiert über aktuelle Themen, über angebotene Unterweisungen etc. falls nötig.

5.0 out of 5 stars Hand down the best GPS tracker around!! Love it!!
Color: OBDVerified PurchaseHands down, the best tracker I have ever used!
I have used 4 or 5 different trackers in the past, but this one beats all the rest I have previously used by a country mile! I originally had a spare mobile phone set up with a 4G sim and a GPS app installed, and it worked OK, but the battery life on the phone wasn't great and I could only charge it whilst I had the ignition on, so after a day or so it would drain the battery life.
So I looked at an alternative option. I purchased a GPS tracker (i forget the name of the brand) which i hardwired into the car via the fuse box - again, this worked OK, but it had a very buggy app and rarely showed the correct location.
So I then purchased a 'mini GPS' sim tracker that claimed to work with any sim carrier...but it didn't and I could even get it to work. Lastly, before I got this device, I purchased the Vodafone curve which has a built in v-sim. Out of all the previous ones, the vodafone curve is the best, and works relatively well for a small monthly fee - but - compared to this item, the curve is nothing.
Now...for THIS item...what a nice, easy and simple device that works...and very well!
After unboxing, there's a slip with an activation code to register the device. Then it was just a case of downloading the devices app and plugging into the OBD port of my car.
No wires. No mess. No fuss. Don't even have to worry about fiddling with a sim card as it has one built in. Don't have to worry about battery life either. It pulls through enough power without the ignition on and no reduction in battery voltage and ...it just works very well. It even has useful features in the app to enable smart security to detect vibration and you can even set it up to detect harsh cornering/braking/accellation etc.
You can see exactly when the engine is started and stopped, where the car has been on each trip...and even follow the map LIVE if you wanted.
Literally the only nag I had was that once I plugged the device into my OBD port, the flap door that covers my port wouldn't close as the device was sticking out. But this was a very easy and simple workaround...the guys who manufacturer this device also offer an extension OBD cable, and its relatively cheap, too. I purchased the cable, and once I installed it, I was able to hide the device in the dashboard and close the flap door. This device also detects and notifies you when it is plugged in or unplugged.
I dont have a bad thing to say about it. I gave had it in the car almost a week now...and I love how simple it is to operate.
The monthly subscription is 100% worth it.

5.0 out of 5 stars Fonctionnement simple et intuitif
Color: OBDVerified PurchaseLe CARLOCK traceur GPS voiture et alarme est efficace et abordable qui offre une tranquillité d'esprit. La géolocalisation précise et les alertes en cas de comportement suspect sont des atouts majeurs. Il est branché directement dans la prise OBD de mon Toyota C-HR, cela fonctionne parfaitement.
L'abonnement mensuel est nécessaire pour accéder à certaines fonctionnalités et la couverture réseau peut être limitée dans certaines zones comme elle parking sous terrain.
J'ai acheté ce produit principalement pour détecter des comportements suspects notamment la nuit, le capteur vibration est assez sensible.
Je suis satisfait de mon achat et de la qualité du produit / service fourni.

5.0 out of 5 stars Prodotto molto valido.
Color: OBDVerified PurchaseIl prodotto funziona bene, fa il lavoro che promette, specie se abbinato ai sensori sulle porte assume un’efficacia maggiore, ovviamente a fronte di un abbonamento mensile o annuale (a discrezione dell’utente) . Unica cosa da ricordare è che quando si fa un aggiornamento dello smartphone, dopo occorre disinstallare e reinstallare l’app da capo, altrimenti non arrivano più le notifiche di allarme. I falsi allarmi che di rado possono arrivare dai sensori delle porte sono generalmente dovuti a vibrazioni causate da spostamenti d’aria della vettura, specie se l’auto è parcheggiata su strade dove le auto viaggiano ad una certa velocità. Infine, con un po’ di manualità il prodotto può essere installato in piena autonomia.

1.0 out of 5 stars 全く使えず
Color: OBDVerified Purchase当方は車を4台所有していますがどの車も全く無反応でした。(国産車・輸入車含む)
対応もしてくれないようですので、そういうものだと理解しました。
