Excellent and easy product to use
Decided to give this a try after having a think about it. Reading some reviews I was a bit unsure of how well it would actually perform, and the answer is quite well! So having installed it on my new Focus, just as a bit of an insight and security on where the car is and anything I should maybe be aware of if someone else is driving the car, it comes in quite handy. I connected it through a OBD splitter cable, hid the carlock device itself away, so it can't be seen, but if the car were to go into the garage they can still connect their OBD reader etc. so the carlock never gets removed. First drive, immediately as I hit the open road it was alerting me of harsh acceleration.. But what do I expect from a Focus ST... It was a bit over sensitive for a start but seems to have sorted itself out and is proving well detailed trip information and quickly to the android app. The app is fairly responsive and easy to use and understand, often a bit on the buggy side, not really sure what it would come down to, but who knows improvements are maybe yet to come. Still this doesn't let the product down as a whole. The device itself never seems to have a problem connecting through it's inbuilt sim, even when miles out of town. Which is quite good considering the 3G connectivity isn't always the best up here in the north of Scotland. Great invention and easy to install right on your drive way. Recommend!

Carlock Tracker
Kit installation was straight forward, plug and play. No sooner as I registered and setup it was easy enough to navigate. 1st Test - Movement Outside the car and in a locked phase within the app, I tried opening the car doors as well as giving it a good nudge similar if a car door hit against it or whether someone was feeling strong enough to move it. Within around 15 seconds I received a phone notification stating the car had some form of movement. Not bad timing wise. Enough for you to return to the car and check for any suspicious activity. 2nd Test - Ignition Likewise to the above, after unlocking the car and starting it. Another notification popped up informing me the car had been started. This appeared again around the 15 second mark. Which may seem a lot if you sit there counting it and a quick getaway could happen. But if you have other forms of protection for it then it may be enough to stop anyone trying to steal it. 3rd Test - Tracking Within the app, your car location has an area marked from where the car was stationary prior to moving. If the car was to move outside of this marked area, you then receive a further notification informing you that the car is now being used on the road and can be tracked via gps. Again this is ideal if you want to track down the whereabouts of your car.

Hand down the best GPS tracker around!! Love it!!
Hands 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.

Great idea, but doesn't quite work
Very easy to install and set up. I have been using it for around 2 weeks now. Thoughts so far, when it works it is fantastic but there are too many issues with the device. 1. Trips are not always logged. Have to contact support to resolve. Takes around 48 hrs. UPDATE* Support has fixed this problem and it is working fine. 2. Smart tag on Bluetooth does not always work. On a few occasions that smart tag has not automatically disabled the security. UPDATE* Support has resolved this problem with my iPhone. Had to enable CarLock in Motion & Fitness. 3. Driving score not logged. Have to contact support to resolve. Takes around 48 hrs. UPDATE* Support has fixed this problem and it is working fine. I am still very happy with the device. I like the logging of each trip, no more arguments about how long a journey took to drive. GPS location helps in large carparks. The vibration sensor is very sensitive, which is good in case there is a hit and run on your vehicle. The battery monitor is in real time and is useful to check your battery health. I would definitly get the extension cable, allows you to place the device in a more suitable location. I have hid mine behind a panel and secured it with cable ties. This should in theory make it harder for would be thieves to find the device and throw it away. The smart tag, still not sure about this bluetooth device. I am waiting on the battery life before making a final verdict.

CarLock experience
I had no intention of buying this item but decided it was a good deal as a direct replacement for my now obsolete TomTom Curfer. If you proved you had one then you qualified to get 20% discount off the price of the CarLock. My Tom Tom Curfer was purchased from a carboot sale (mistake now realized), and seemed like a good deal at £3 but only when I tried to use it did I realize that it is not possible to register the Tom Tom anymore. To not feel I had wasted my money in vain I stumbled across the discount being offered on the Carlock. As most cars have an OBD port, post 1996, this was an obvious choice for me as it made for easy fitting. I primarily wanted to keep track of our teenagers now driving in the house and this seemed the obvious choice. The app is very easy to use and configurable to our needs. I didn't want the Carlock to automatically set to on when the engine has stopped and it was easy to disable this feature. I can't really fault it but if there was one niggle it is that after the first month you seem to have to subscribe to a monthly or yearly charge to continue to use the features of the device as it uses the built in SIM to send all its data. It does seem a small cost for the overall sense of control I now have on the vehicle I decide to attach it to. If I had researched into it a bit more before purchasing I probably would have come across this charge but missed it at the time. I particularly like the way it logs all the journeys made and the data can be downloaded in either XLS or CSV format for future access.

Not fit for purpose.......Do not buy.
On paper, and according to the CarLock sales spiel, this should be a great addition to vehicle security but from my personal experience the Carlock is as much use as an ornament, or a chocolate fireguard. It has not worked properly since I installed it on my 2019MY Mercedes 450GLE. The engine start, vibration detected, and vehicle battery information alarm notifications are triggered correctly on the App, but there was no vehicle tracking, or vehicle location position recorded following the initial install. It located my home install location correctly but thereafter nothing about the vehicle usage, or its whereabouts was ever recorded. No matter how many miles I drove, or wherever I went, my vehicle was shown as never having moved off my driveway. This was despite the fact that the tracker app showed the device was was being monitored by up to 18 satellites. I reported the problem to their support team straightaway and for a month they were apparently "working" on it. I say apparently as they never bothered to update me. The only time I ever heard anything was when I chased them, which I did every few days. Even then all I ever got were platitudes "we are working on it". The silence has been deafening! I requested a replacement a number of times but this was ignored until over a month later when they agreed that I should return the unit, and they would send a replacement. Which they duly did and re-reimbursed the postage costs I installed the new unit which had exactly the same problem as the one I had returned. This time though on installation it failed to register any tracking satellites. I reported the problem to CarLock (UMTR Group), and was informed, quote "The problem is being solved and you will be advised about it soonest" unquote. A day later I was contacted again and informed, quote " We have been discussing the issue with our "R&D. They have had a deeper insight but the only conclusion is that somehow the device is not connecting and their guesstimation is that the problem is - do not get us wrong, please - in the car that seems like being heavily armored" unquote. (Their words and spelling). I have written back to them informing them that my vehicle is not armoured, or protected in any way. Its a standard Mercedes GLE 450. I had such high hopes for this device as a complement to my existing vehicle security system but I've now given up and returned it to Amazon. It might be something to do with my vehicle but the device clearly does not work. Furthermore the technical support is the worst that I have ever encountered. I would definitely not recommend.

Peace of mind
I purchased the obd port tracker along with the obd slim splitter cable which enabled me to hide my CarLock tracker yet still have my obd port available for use, the tracker is brilliant and is very accurate, combined with the app which shows you your driving statistics, speed, harsh braking,cornering etc, it really is a great product and gives me piece of mind knowing my car is protected 24/7 and also helps me improve my driving. I fitted this over 3 months ago and had no issues whatsoever and I carnt see any in the future it is a solid tracker and customer support is excellent, I’ve recently purchased the CarLock Bluetooth tag which enables and disables the tracker when you approach/leave your car again giving me peice of mind, I hope this helps someone who is considering buying this tracker, I say go for it you won’t regret it

Not Great
First day it showed the correct address I live in, but after that it constantly shows the car at neighbours next door, though it's in my driveway. Also, just after a couple of hours of parking ( overnight ) it says battery low, what will happen if I leave it parked for a week, the tracker will definitely stop working. Not to mention the late notifications that sometimes won't come through at all ...

Peace of Mind for Parents: Why CarLock is a Must-Have for New Drivers
I'm so glad I purchased the CarLock system—it has truly been a game-changer for peace of mind, especially with my son being a new driver. With the rising number of accidents and the limitations of police assistance in our area—particularly when it comes to hit-and-runs or minor collisions where police involvement is only triggered in more serious cases—it can be difficult to resolve situations without proof. CarLock has provided a reliable solution to that problem. Here's why I’m so impressed: 1. Real-time Tracking: I can track my car, while my son is driving in real-time, which allows me to know exactly where it is at all times. This feature has been invaluable, especially when he’s out on the road. 2. Speed Limit Alerts: I can set a speed limit for the car, and if it's exceeded, I receive an immediate notification. This has helped me monitor his driving habits and ensure he’s staying safe. 3. Device Disconnection Alerts: If someone tries to tamper with or disconnect the CarLock device, I’m notified right away. This adds an extra layer of security, especially if the vehicle is left unattended. 4. Customizable Settings: I can disable the CarLock sensors, set lock timers, or even schedule the system to be active only during certain hours. This flexibility is really useful for tailoring the alerts to my needs. 5. Vibration Detection: If there’s any unusual vibration (such as sudden impacts or aggressive driving), I receive an alert, giving me peace of mind that I’ll know if something unusual happens. 6. Harsh Driving Monitoring: I can monitor harsh driving behavior, such as rapid acceleration, hard braking, or sharp turns, helping me identify and address any potentially dangerous driving habits. 7. Journey Tracking: The system tracks the duration of trips, giving me insights into how long it takes to get from one place to another. The detailed map feature even shows street and freeway views, which is incredibly helpful for keeping track of routes. So grateful I bought this! Just today, the CarLock alarm went off, notifying me that my son had exceeded the speed limit I set. I was able to call him when I knew he'd made it to his destination and remind him to slow down—helping him stay safe on the road. CarLock has given me such peace of mind knowing I have real-time visibility and control over my son's driving habits. It’s definitely a must-have for any parent of a new driver!

Je recommande
Super produit. Très facile d'installation et très fiable dans l'utilisation. Je l'utilise pour une flotte de 14 véhicules. Cela me permet d'anticiper le mode de conduite et les frais liés à l'utilisations des véhicules. SAV très réactif et commerçants. Juste l'interface à améliorer pour la gestion de plusieurs véhicules mais cela est du détail.

Great product, just a few issues
I love the ease of use and the performance of this product, it is cheaper subscription than the stock GPS programs that come through the car manufacturer. The good: it's easy plug and play. The app works very well and has no glitches. Notifications are great and come in within seconds of the alarm being triggered. I love the driving score, especially if you have someone else driving your car. The bad: it's too large that I couldn't apply the Ebrake on dodge charger with it on, so I had to get an extension. Which brings me to the next issue, I'd love to see a double bypass type of extension cord (similar to the one that comes with the z automotive tazer) this way criminals won't find it easily and won't be able to disable it. The last issue I had was at the beginning, but I believe it has been fixed, it was that the GPS would show the car at a place that I was at hours prior, and it'd take a day for it to snap out of it. Over all, good product and I'd recommend it.
