CarLock - Advanced Real Time Car Tracker & Alert System.

CarLock monitors and alerts you on your phone when your vehicle is moved, when the engine starts, if unusual vibration is detected & even if the device is disconnected!

We love our teens but they can be entirely different people behind the wheel. CarLock detects harsh acceleration (drag racing), hard breaking & sharp cornering (stunt driving).

CarLock actively monitors the health of your vehicle and alerts you in advance if your car battery is running dangerously low or is experiencing high battery drain.

Included is also a detailed trip tracking which lets you monitor where your car has been. You'll be notified if your car is stolen or a "trusted" driver is going off course!

CarLock uses cloud computing, internet storage, GPS tracking and a modern day app. You get all this for only $9.60 per month and the first month is FREE! Work's on AT&T's network.

CarLock supports multiple cars on one account. The device is compatible with all cars manufactured after 1996.

Love it

I’m loving the “CarLock” app and device. I brought the “CarLock” plug in OBD device because I’ve recently have brought new wheels for my vehicle and didn’t want to be a victim of theft. I also didn’t want to pay $200 for a car alarm system so I found “CarLock” as an option. There’s no way for anyone to jack up your car and steal your wheels without this device notifying you or unwanted vibration movement of your vehicle. The only thing I wish “CarLock” implemented was a more alarming notification for when there is unwanted vibration of the car. The notification that is given now isn’t loud enough to be heard or waken out of a sleep for. There’s should be some that will cause you to jump out of your sleep to check and see what’s going on.

P.S, it would be wonderful for those that have apple watches to being able to arm/disarm the CarLock device. It’s sometimes a pain pulling out the phone to do so.

New App is Missing Features from Old App

The new app looks nice, but please bring back the timestamps. The old app used to provide a timestamp every time the GPS location data was refreshed. It also provided a more detailed view of battery voltage, and it showed what specific time the battery had a specific voltage. This is useful information which provides peace of mind. I like knowing that everything I'm seeing with my car is up to date. I don't like the feeling of possibly being misled into thinking my car is safe when in reality I'm viewing information that hasn't been updated for many hours.

Very impressed

This has everything you need to protect the second biggest investment of your life, your House is number 1, they say your car is the second biggest investment. It has all the features I want and need! Does everything manufacturer describes? Fees are cheaper than anyone I’ve seen? What more can you ask for! If it’s unplugged your notified, car turns on your notified! This is hands down prob the best way to protect your car even more so than a car alarm? Tracking, detection, vehicle health this literally has it all! Can’t say enough
